TEXAS BULLETIN NO. 577 SEPTEMBER, 1939 DIVISION OF CHEMISTRY Commercial Fertilizers in 1933-39 and Their Uses AGRICULTURAL AND MECHANICAL COLLEGE OF TEXAS T. O. WALTON, President [Blank Page in Original Bulletin] This is the annual Fertilizer Control Bulletin. It contains statistics regarding fertilizers sold in Texas, information regarding the fer- tilizer law, and analyses of samples 0f the fertilizer sold by different manufacturers. The extent to which the various manufacturers are coming up to their guarantee is shown; The total sales of fertilizer in Texas for 1938-39 were 93,115 tons. In 1937-38 the sales were 79,640 tons. In 1936-37 they were 84,938 tons. Cottonseed meal sold as a feed but used as a fertilizer was not included in these totals. Sales of fertilizer were a little more than last year. Practically all the sales of mixed fertilizers were confined to about 20 analysesL Tables are given showing the extent to which the various fertilizer manufacturers met or exceeded their guarantees. The cost of fer- tilizer was slightly less in 1938-39 than in 1937-38. Suggestions are given for the use of fertilizers on various crops.

S. Fraps, State Chemist; T. L. Ogier, Associate State Chemist; and S. E. Asbury, Assistant State Chemist Fertilizer laws require fertilizer to be correctly labeled so that the pur- chaser can know what he is getting. The object of the fertilizer law is to protect the farmer or other users of fertilizer against misrepresentation of the composition or fertilizing value of the fertilizer as well as manufac- turers and dealers against unfair competition due to such misrepresenta- tion. The first Texas fertilizer law was passed in 1899. It was revised and amended in 1911. The results of the fertilizer inspection have been publish- ed in bulletins of the Texas Agricultural Experiment Station regularly since 1906. This is the thirty-seventh Fertilizer Control Bulletin. It con- tains statistics, definitions of terms, a report on the analyses made in en- forcing the provisions of the Fertilizer law, and information regarding the use of fertilizers. Explanation of Terms Nitrogen refers to the total nitrogen in the fertilizer. It is necessary in proper amounts for the development of all parts of the plant, but an excess of nitrogen delays maturity and is liable to promote growth of stalk and leaves at the expense of fruit. Nitrogen is needed by many Texas soils, especially the sandy soils in the eastern and northern parts of the State. Since nitrogen is used in comparatively large quantities by plants and is, to some extent, washed from the soil, it is usually the first element to be- come depleted from a fertile soil. Available phosphoric acid is the phosphoric acid (P205) in fertilizers which can be taken up quickly by plants. Phosphoric acid promotes the fruiting of plants, though it is also necessary for the development of all parts of the plant. Total phosphoric acid is the entire quantity of the phosphoric acid (P205) present, whether highly available or not. A guarantee of total phosphoric acid in place of available is made in bone, tankage, rock phosphate, and basic slag. Potash guaranteed in a fertilizer is required by law to be soluble in water. Potash, like nitrogen, is needed by all parts of the plant, but especially by stalk and leaves. An excess of potash delays maturity and is liable to pro- mote growth of the stalk and leaves at the expense of the fruit. When potash is abundantly supplied, plants may take up more than they need. Potash is present in soils more abundantly than phosphoric acid. 6 BULLETIN NO. 577, TEXAS AGRICULTURAL EXPERIMENT STATION Valuation per ton represents the approximate average cost of the plant food in the unmixed fertilizer, at retail. It is usually smaller than the price at which the mixed fertilizer is sold, but since it is an average, it may be greater than the prices of some of the unmixed fertilizer materials. The selling price includes cost of mixing, bags, transportation, the profit of the manufacturer if any and that of the dealer. The valuations are decided on about September 1, and the prices often change before the chief active fertilizer season, which is February to April in Texas. The valuation sums the value of the three plant foods shown in the analysis into a single figure, and is convenient for this purpose. The fertilizer law permits a deficiency of less than ten per cent in one plant food to be compensated by an excess of another, but if the valuation is four per cent less than the guaranteed valuation, a rebate must be paid to the purchaser. The valuation found compared with the valuation guaranteed shows whether or not the fer- tilizer as a whole is better or poorer than the guarantee as a whole. The following valuations were used in 1938-39: Cents per pound Nitrogen . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . _ . . . _ . . . . . . . . . ..12.0 Available phosphoric acid .............................................................................................. __ 6.5 Total phosphoric acid in Thomas phosphate, tankage, and bone meal ...................................................................................... .. 4.0 Total phosphoric acid in rock phosphate .................................................................. .. 1.5 Potash .................................................................................................................................... .. 6.0 Names of fertilizers. Fertilizers are frequently named by numbers, such as a 4-8-4 fertilizer, a 6-12-6 fertilizer and so on. In such names, the first figure stands for the percentage of nitrogen, the second for the percentage of available phosphoric acid, and the third for the percentage of water- soluble potash. This is a short and accurate method of naming fertilizers. Information on the Fertilizer Bag and Tag A fertilizer tax tag is required to be placed on every bag of fertilizer before it is offered for sale or sold. The guaranteed analysis of the fertilizer is required by law to be printed on the bag or on the tag attached to the bag, so that the purchaser can see what he is buying. Total phosphoric acid may be guaranteed for bone or tankage instead of available phosphoric acid. A guarantee of total phosphoric acid is required in Thomas phosphate or rock phosphate. The information required on the package is as follows: Net weight Name of fertilizer in full Name and address of manufacturer Guaranteed analysis: Nitrogen, per cent Available phosphoric acid, per cent Potash, per cent How to Calculate the Valuation The valuation of a fertilizer is calculated by multiplying the composition by the valuation of each unit of plant food and adding the products. A unit is one per cent of a ton, or 20 pounds; so if the valuation of nitrogen is COMMERCIAL FERTILIZERS IN 1938-39 7 12 cents a pound, the valuation of a unit is 12 x 20 z $2.40. The valuation of a unit of available phosphoric acid at 6.5 cents a pound would be 6.5 x 20 —_— $1.30; the valuation for a unit of potash at 6.0 cents per pound would be $1.20. The following is an example o.f a calculation at the prices given above: Valuation of 4-8-4 fertilizer Nitrogen .... .. 4 x $2.40 I $ 9.60 Available phosphoric acid .......................................................... ..8 x $1.30 I $10.40 Potash _ . . . . . . . . . . _ . . _ . . . . . . . . . . . . . . . . _ . . . . . . . . . .. ...4 x $1.20 I $ 4.80 Total valuation per ton ...................................................... “$24.80 Fertilizer Analyses to be sold in 1939-40 The grades of fertilizer sold in Texas are limited in number. This standardization aids the farmers to become familiar with the different kinds of fertilizer, enables him to decide more readily on the proper kind to be used, enables the agricultural worker to make definite recommenda- tions, and reduces the cost of manufacture and handling, thereby also re- ducing the cost to the consumer. At a conference with fertilizer manufac- turers doing business in Texas, Louisiana, Oklahoma, and Arkansas in July, 1939, grades of mixed fertilizer were adopted for these states. This was the fifteenth such conference for Texas manufacturers, and the-seventh joint conference. Changes are made at practically every meetinguGrades which have little sales may be dropped, and new or experimental grades may be added. The grades adopted for Texas are as follows: GRADES 0-12-4 4-12-4 6-12-6 3-10-0 5-15-0 10-0-10 3-10-3 5-15-5 10-10-0 4-8-4 6-8-4 10-20-0 4-8-6 6-8-8 10-20-10 4-8-10 6-9-3 11-48-0 4-10-0 6-1 -7 15-30-15 16-20-0 MATERIALS Activated sludge Manure salts, 30% Bat guano Muriate of potash, 50% Basic slag Nitrate of soda, 16% Bone meal Nitrate of soda and potash 15-0-14 Calcium nitrate Sheep manure Cal-Nitro, 16% Sulphate of ammonia, 20% Cal-Nitro, 20% Sulphate of potash, 48% Cottonseed meal Superphosphate, 18% Cyanamid, 21% Superphosphate, 20% Cyanamid, 22% Superphosphate, 32% Ground phosphate rock Superphosphate, 45% Kainit, 20% Soft phosphate with colloidal clay Lawn and Garden Tankage 8 BULLETIN NO. 577, TEXAS AGRICULTURAL EXPERIMENT STATION Quantity Sold The quantities of commercial fertilizer sold in Texas for several seasons, from September 1 to August 31, are given in Table 1. These are the actual sales as reported by the manufacturers, and not the tag sales. The tag sales are always a little larger than the actual sales. The sales in 1938-39 were a little higher than last season. The largest sales so far made in Texas were 187,215 tons during the season 1928-29. Fertilizer statistics for a num- ber of years to August 31, 1926, have been published in Bulletin 350, and from 1926 to 1938 in Bulletin 572. Table 1.

The average retail selling price is the average of the cash retail prices furnished to the fertilizer inspector by the dealers. The prices of the same fertilizer may be different in different towns on account of differences in cost of transportation or for other causes. The retail price includes handling costs, carrying charges, and the dealer’s profits, as well as the cost of the plant food used in the materials from which the fertilizer is made. The average valuations found (Table 3) exceeds the guaranteed valua- tions in almost every case. The exceptions are 5-15-0, 5-15-5, 6-8-8, 10-20-0, 10-20-10, and 16-20-0. In all of these, however, the valuations found are only slightly below the valuations guaranteed. Table 3.

COMMERCIAL FERTILIZERS IN 1938-39 11 Cost of Plant Food Table 4 contains the calculated retail cost of a pound of nitrogen, of available phosphoric acid, and of potash, in cents per pound, as calculated from the cash selling prices per ton given in Table 3 and the guaranteed composition. For the purpose of these calculations it was assumed that the prices were in the same ratio as the valuations. As the prices of the same fertilizer in different places vary, these figures are not correct for any particular locality, but represent averages only, and are for purposes of comparison. The prices were collected by the inspectors from retail merchants handling fertilizer. Grades used extensively near the factories would average a lower price than those used at a distance on account of lower transportation costs. The fertilizers with the lowest prices of plant food are given first in the table. Fertilizers for lawns, gardens and flowers can be secured at a reasonable price but a few of the fertilizers in small packages are sold at a price of hundreds or even thousands of dollars per ton. The cost can be easily esti- mated from the price and the weight of fertilizer in the package. Table 4.

Sheep Manure 77.65 42.06 38.83 ‘Total Phosphoric Acid. 12 BULLETIN NO. 577, TEXAS AGRICULTURAL EXPERIMENT STATION Cost of nitrogen. The 11-48-0 was the cheapest source of nitrogen, cyana- mid was next, 16-20-0 third, sulphate of ammonia came fourth and 10-20-10 fifth. Pulverized sheep manure was the most expensive source of nitrogen, 3-10-0 next, followed by 4-10-0 and calcium nitrate fertilizer. Nitrogen cost more in most of the mixed fertilizers than in sulphate of ammonia or cyanamid because it costs to mix the fertilizers. The lowest-priced nitrogen i in the mixed fertilizer was in the 11-48-0, followed in order by the 16-20-0, 10-20-10, 6-12-6, and 5-15-5. The 4-8-4, the most popular fertilizer, was also high in price. Nitrogen was lower in price than last season in some fertilizers and higher in others. The difference averaged .20 cents a pound less for nitrogen in sulphate of ammonia, 1.23 cents less for that in 3-10-3, 1.40 cents less for that in 4-12-4, and 1.02 cents per pound less this year in 4-8-4. Cost of phosphoric acid. The cheapest source of phosphoric acid was 11-48-0, then 16-20-0, followed by 10-20-10 and then 20% superphosphate. The cost of available phosphoric acid was about 0.29 cents less per pound in 20 per cent superphosphate than in 18 per cent. Omitting the household fertilizers, phosphoric acid was most expensive in pulverized sheep manure, then in 3-10-0, and then 4-10-0, and 0-12-4. Available phosphoric acid was 0.08 cents a pound higher in 4-8-4 than it was last season, and 0.17 cents a pound lower in 4-12-4 than last year. Cost of potash. Muriate of potash was the cheapest form of potash, fol- lowered by 10-20-10 and then 6-12-6. Pulverized sheep manure the most ex- pensive in mixed fertilizers, followed by 0-12-4 and then 3-10-3. Potash cost 1.30 cents a pound less in muriatc of potash, than it did last season, but 0.12 cents a pound more in 4-8-4, and .11 cents a pound less in 4-12-4. Relation of Cost to Concentration of Fertilizers Certain fertilizers are sold which contain the plant food in the same ratio so that, so far as nitrogen, phosphoric acid and potash are concerned, they are the same fertilizer except in concentration, or strength. The ratio of plant food in the 4-12-4 and 5-15-5 fertilizers is exactly the same, as the proportions are three parts phosphoric acid to one of nitrogen and one of potash. The 3-10-3 fertilizer has practically the ratio 1-3-1. Table 5 shows the approximate cost of nearly equal quantities of plant food in these fertilizers at the average prices given in Table 3. One ton of 6-12-6 costs $6.61 less than an equal quantity of plant food in 1% tons of 4-8-4. The plant food in 1.25 tons of 4-12-4 costs $1.79 more than an equal quan- tity in 5-15-5. The 1.67 tons of 3-10-3 cost $3.30 more than the 1.0 tons of 5-15-5, but when an allowance of $2.27 is made of the 33 pounds more phosphoric acid it contains, the plant food in 3-10-3 costs $1.03 more. Similar differences are to be seen with the other grades. The most concen- trated mixed fertilizer was the cheapest per pound of plant food, or to put it another way, the highest-priced fertilizer per ton may be the lowest COMMERCIAL FERTILIZERS IN 1938-39 13 Table 5.

This difference is caused partly by freight charges, partly by the cost of bagging, etc. The higher cost of manufac- ture of the more concentrated fertilizers is frequently more than offset by the cost of freight, bags, etc. As shown in Table 4, the cost of phosphoric acid averaged slightly less in 2'0 per cent superphosphate than in 18 per cent. Comparing Cost of Fertilizer The relative money value of two or more kinds of fertilizer may be roughly compared by dividing the price at which the fertilizer is sold per ton by the valuation per ton of the fertilizer. Guaranteed valuations for imany grades for the season of 1938-39 may be somewhat different, these calculations may be used for comparative purposes. For example, if a 4-8-4 fertilizer sells for $29.00 a ton and a 6-12-6 fertilizer for $37.20, which is cheaper? Using the valuations from Table 3, for 4-8-4, the selling price $29.00 divided by the valuation $24.80 gives $1.17; for 6-12-6, the selling price $37.00 divided by the valuation $37.20 gives $1.00. Thus one dollar of valuation costs $1.17 in 4-8-4, and $1.00 in 6-12-6. Therefore, the 6-12-6 is cheaper. Similar calculations may be made for other grades and for other prices. Of course the suitability of the fertilizer to the soil and crop must be considered in addition to the relative cost of the plant food. Free Analyses Purchasers of commercial fertilizers for their own use (but not for sale), can secure a free analysis of a sample provided they take a legal sample. Those who desire the free analysis of a sample of commercial fertilizer should write for a blank, “Application for Free Fertilizer Analysis,” to the State Chemist, College Station, Texas, before taking a sample. The proper sampling of a fertilizer requires care and the law requires it to be taken in a certain way so that a fair sample is taken. If the sample is not properly taken, it does not represent the fertilizer sampled, and the analysis may be 14 BULLETIN NO. 577. TEXAS AGRICULTURAL EXPERIMENT STATION better or poorer than the goods actually are. This privilege of a free analysis applies only to fertilizers tagged, and sold under the fertilizer law and to samples properly taken so that they represent the goods sampled. Analysis of fertilizers, 1938-39 Samples of fertilizers were collected from the grades being sold in many towns and cities. The chief places of sales were visited several times. The number of samples registered for analysis was 1,208. Table 8, near the end of this Bulletin, contains a list of the samples of fertilizer subjected to analysis in the season ending September 1, 1939. Analyses below guarantee are brought out in heavy type. Practically all samples of fertilizer were collected by our inspectors. Analyses and inspec- tion were made by S. E. Asbury, T. L. Ogier, Waldo Walker, J. L. Kelch, Geo. Smith, Sam Greenberg, and Leon Miller. Relation of Valuation Guaranteed to Valuation Delivered Table 6 contains the average guaranteed valuation, and the average valua- tion found by our analyses, for all manufacturers doing business in Texas. In the preparation of this table, all analyses made were averaged, even though several were made of each brand and fertilizer materials are in- eluded as well as mixed fertilizers. Averages Below Guarantee Whenever any lot of fertilizer is 4 per cent or more below guarantee, the law requires all persons who have sold this lot of fertilizer to make good the deficiency to all purchasers. This rebate is paid by the manufactur- er to the dealer and by the dealer to the customer. The number of lots on which rebates were paid by each manufacturer is shown in Table 6. Non-Acid Forming Fertilizers Ordinary fertilizers are acid forming, and when used for a number of years on soils with a low buffer capacity may make a soil acid, or more acid, if it was already acid to start with. Non-acid forming fertilizers are made by the use of proper amounts of ground dolomite, which is calcium and magnesium carbonate, or by the selection of suitable fertilizing in- gredients. Limestone is not suitable because it reverts the available phos- phoric acid and causes it to become insoluble. In the eastern part of the United States, where fertilizers have been used for a long time and where the soils are already acid, ordinary fertilizers may not give as good results in crop yields as non-acid forming fertilizers. Non-acid forming fertilizers are recommended for use on acid soils which are likely to become still more acid with ordinary fertilizers.

Where the soils are neutral or slightly alkaline, as is the case in large areas of limestone soils, ordinary fertilizers are preferable to non-acid forming fertilizers. Some plants require slightly acid soils for best results. An acid-forming fer- tilizer may be better on an alkaline soil than a non-acid forming fertilizer. For further information see Progress Report No. 594. Only two brands of fertilizer sold in Texas this season were claimed to be non-acid forming.

Relation to Experiment Station Work The work of the State Chemist is closely related to the chemical work of the Experiment Station. In his capacity as Chief of the Division of Chemistry of the Experiment Station, the State Chemist is carrying out extensive investigations into the fundamental properties of soils, especially with respect to their content of plant food. This work is related closely to the use of fertilizers and is connected with investigations as to the agricul- tural values of fertilizers required by the Fertilizer Control, for fertilizers vary in effect upon the different soils. Soft Phosphate With Colloidal Clay Soft phosphate with colloidal clay is a natural phosphate of lime contain- ing 20 per cent of total phosphoric acid or more. The phosphate of lime is so finely divided that some of it is termed colloidal. The availability to plants of the phosphoric acid of soft phosphate with colloidal clay is on an average about 40 per cent of that of the available phosphoric acid in 20 per cent superphosphate. Additional information is given in Bulletin 509. COMMERCIAL FERTILIZERS IN 1938-39 17 Sulphur, Gypsum, Manganese, and Other Secondary Fertilizing Elements Our present evidence indicates that manganese, magnesia, sulphur, calcium, boron, iodine, zinc or other secondary fertilizing elements do not need special attention as additions to Texas soils. Sulphur, and calcium are present in large quantities in practically all mixed fertilizers, and small quantities of the other elements are also present. We are unable to recommend the use of sulphur or gypsum alone as a ' fertilizer in Texas because Texas soils need nitrogen, phosphoric acid or potash much more than they need sulphur, and the sulphur or gypsum does not supply any of these plant foods. The experiments which have been carried out do not give results which justify the use of such materials as fertilizers alone (see Bulletins 408 and 414). This also applies to the natural mixture of sulphur, gypsum, sulphuric acid and other substances, which various parties and concerns have attempted to sell or exploit as a fertilizer or soil amendment. It is not recommended for use as a fertilizer and does not give results on soils which need fertilizer, as shown in Bulletins 408 and 414. For plants which do best on an acid soil sulphur is sometimes used to acidify soils that are alkaline or neutral. The organisms in the soil oxidize the sulphur to sulphuric acid and thus in turn acidifies the soil. The oxi- dation requires two or three months. The quantity to be used depends upon the buffer capacity of the soil for acid, and may range from-a few hundred pounds to several thousand pounds per acre. In the latter case, acidification of spots is best. The value of a sulphur for acidifying the soil depends on the quantity of sulphur present: a material containing 85 per cent of sulphur is 41A times as strong as one containing only 20 per cent of sulphur. Plants suffer from a yellowing of the leaves, known as chlorosis, usually due to deficiency of iron on some limestone soils in Texas. The presence of car- bonate of lime prevents the plant from taking up (or utilizing) sufficient iron. Most of these soils contain such large quantities of carbonate of lime that broadcast applications of sulphur are soon neutralized. A sufficient number of acidified spots may prevent the chlorosis. The acidified spots may be made by digging post holes to depths of 2 to 3 feet, mixing the dirt with sulphur and returning the mixture to the holes. Holes may also be made with a pointed iron rod and filled with the sulphur. Investigations on the use of manganese sulphate for Texas soils are given in Bulletin 432. The results of the experimental work do not justify recom- mendation of the use of manganese sulphate on Texas soils. Greensand A report of investigations regarding the value of greensand as a fer- tilizer was published in Bulletin 428. The availability of the potash and phos- phoric acid in greensand was found to be low. Greensand has little fer- 18 BULLETIN NO. 577, TEXAS AGRICULTURAL EXPERIMENT STATION tilizing value but can be used in quantities of 5 to 40 tons to an acre on- land near to the deposits where it can be mined and applied at a cost closely related to its value. It does not contain sufficient fertilizer value to justify attempting to market it. Polyhalite and Sewage Sludge Polyhalite, a mineral found in deep deposits in western Texas and in New Mexico, contains about 12 per cent potash, which is only partly soluble in water, but which is readily available to plants. Additional information is given in Bulletin 449. Digested sewage sludge is low in plant food, and the nitrogen has a low availability. Dried activated sludge contains about 5 per cent nitrogen and 2 per cent available phosphoric acid and the nitrogen has a good availability to plants. Additional information is given in Bulletin 445. GENERAL CONSIDERATIONS ON THE USE OF FERTILIZERS Fertilizers supply the three forms of plant food most necessary for grow- ing crops, namely, nitrogen, phosphoric acid, and potash. For best results with fertilizers, other conditions should be favorable, such as a well-drained soil in good physical condition, a well prepared seed bed, good seed, good cultivation, sufficient rainfall or irrigation, and suitable rotation. Nitrogen is the most expensive plant food, and for this reason the amount of fer- tilizer used generally does not supply all the nitrogen required by the crop. A cropping system which includes the regular growing of suitable legumes‘, such as clover, cowpeas, soy beans, velvet beans, peanuts, or alfalfa, should be followed for the purpose of securing nitrogen from the air, provided the legume crops can be grown to advantage. A suitable rotation also adds organic matter to the soil, utilizes time and labor to better advantages, aids in controlling insect pests and plant diseases, and has other favorable ef- fects. The proper fertilizers to use depends upon the kind of soil, the climate, the crop, how long the soil has been in cultivation, whether or not legumes have been turned under or grazed off, what the soil will produce without fertilizer, what the rainfall, temperature and other conditions permit it to produce with fertilizer, and other conditions. Soils which have been in cultivation a long time, or very sandy soils are usually more deficient in nitrogen than new soils or clay soils. Soils having a rotation which includes legumes need less nitrogen than those cropped constantly to non-legumes. Clay soils and soils with clay or. loam subsoils in cultivation less than 15 years need little potash in Texas for ordinary farm crops, but light sandy soils with sandy subsoils may need potash. Larger amounts of fertilizer COMMERCIAL FERTILIZERS IN 1938-39 19 may be profitably used on crops with a high acre value, such as fruit or truck crops, than on ordinary farm crops, such as corn or cotton. The fer- tilizer on cotton may profitably be twice as much as that used on corn. Best results are secured by a well-balanced supply of plant food in the soil. An excess of nitrogen or an excess of potash is shown by the produc- tion of a heavy stalk or vine, with a deficiency of fruit or delayed maturity. If such land has not been fertilized, probably the best fertilizer to use is 200 to 300 pounds of superphosphate to the acre. This will frequently (but not always) promote fruiting. If a fertilizer has been used, the remedy is to decrease the percentage of nitrogen and to increase the percentage of phosphoric acid in subsequent applications. The percentage of potash may also be decreased. Excess nitrogen in soil when truck crops are grown may produce rapid growth with soft tissues, which do not stand up well under shipment. Straw- berries, for example, produce large fruits which are not firm enough to ship well. Lettuce, cabbage, and similar crops may not be firm enough to stand shipment. Increased quantities of potash will not prevent softness caused by excess of nitrogen. Excess of nitrogen renders some plants more liable to attack by some diseases. Excess of nitrogen also delays maturity. Excess of potash, like excess of nitrogen, delays maturity of the crop. A well-balanced fertilizer should be selected, due consideration being given to the soil, the crop, the character of growth, and other conditions. A well-balanced fertilizer will produce a crop that is firm and ships well. How and ‘When to Apply Fertilizer Fertilizer is generally applied under the seed at the time of planting or previous to planting. It should not touch the seed, but is placed in a narrow band one to three inches below the seed or preferably at the side 2 to 3 inches from the seed or plants and at the same level. A combined planter and fer- tilizer distributor may be used, but care should be taken to select a machine which applies the fertilizers properly, as some machines are not satisfactory. Fertilizer may be placed in the ground at the time of planting or not more than three weeks before planting. If applied too early, there is danger of loss of plant food by fixation and leaching. If more than 800 pounds of fertilizer to the acre are to be used, applica- tions are best made partly in the furrows and partly broadcast. However, with some vegetables it is best to apply all the fertilizer in the furrows. If desired, high analysis fertilizer may be mixed with fine dry sand before it is applied in order to secure a more uniform distribution. 20 BULLETIN NO. 577, TEXAS AGRICULTURAL EXPERIMENT STATION In dry sections, where the soil above the seed is liable to dry out, the fertilizer may be applied on the firm soil at the same depth as the seed but by side of the seed. Sometimes it may be advisable to put it in when the land is bedded, especially on heavy soils where there is little danger of loss by leaching. When fertilizers of high analysis are used, especial care should be taken to mix them with the soil, and not to apply them close to the seed or to the roots of growing plants. These fertilizers are quite strong, and burning or other injury may result if they are placed closely to roots of plants. Fertilizers in solution are sometimes applied when plants are set out, to plotted plants or in home gardens. A pint of such a solution applied to tomatoes when transplanted has been found to give a considerable increase in yield and to help the plant root. About one ounce of 6-8-4 or 6-12-6 to a gallon of water is used for such solutions, but many fertilizers are not sufficiently soluble in water to be used for such purposes. How Much to Apply It is best for farmers not experienced in the use of fertilizer to begin with moderate amounts, such as 200 to 400 pounds to the acre for cotton or corn and 400 to 800 pounds for truck crops. Larger amounts may then be tried on a small scale and then these larger amounts used if these trials appear to justify it .The approximate amounts to use are indicated below. A farmer should be guided by his own experience in the selection and use of fertilizers. Side Dressings More than one application of fertilizer is not usually recommended for cotton or corn. Under exceptional conditions, however, more than one ap- plication may be made for cotton or corn. These conditions would include: (1) when more than 500 pounds of fertilizer to the acre is to be used; (2) when the plants appear to be suffering from a deficiency of available plant food, particularly nitrogen; (3) if the weather in the spring has been exces- sively wet, so as to cause considerable leaching; (4) if the soil is a deep sandy soil, where the plant food is likely to leach out. Bulletin No. 490 con- tains additional information. Side dressings of cotton with nitrate of soda, sulphate of ammonia, or other sources of nitrogen are not generally to be recommended, but may be used when the fertilizer applied at planting does not contain enough nitrogen, or on deep sandy soil, where there may be considerable loss from leaching. Under such conditions, 100 pounds per acre of nitrate of soda or sulphate of ammonia may be applied to cotton just after chopping‘. Corn which was not fertilized before planting may frequently use to advantage a side dressing of nitrate of soda or sulphate of ammonia, ap- plied when the corn is knee-high. COMMERCIAL FERTILIZERS IN 1938-39 21 Side dressings are frequently applied to truck crops. In such case a com- plete fertilizer is applied before or at the time of planting, and one or more side dressings of sulphate of ammonia or nitrate of soda afterwards. There is little danger of loss of phosphoric acid or potash by leaching, while soluble nitrogen may be lost by leaching. Fertilizers for East Texas The soils of East Texas as a general rule respond well to fertilizers, and the recommendations made here apply chiefly to this section of the State. Many of the soils of East Texas are sandy and low in phosphoric acid and nitrogen; they are usually better supplied with potash but sometimes they are low in potash. The heavier soils and the bottom lands are much better supplied with plant food than the upland soils. Fertilizers for Black Lands The heavy black limestone soils of Central Texas, especially the Houston clay and the Houston black clay, do not give as much response to fertilizers as the sandy soils of eastern Texas. Sometimes they respond to applications of nitrogen and phosphoric acid, although in general the use of fertilizers on these soils has not been profitable. In some cases they give satisfactory results one year and unsatisfactory the next. These soils appear to need vegetable matter first, such as is supplied by well rotted manure, by legume crops turned under or grazed off, or by winter crops. A rotation is also of advantage (see Bulletin 365). Sandy lands in this section will probably respond to fertilizer, though little has been used on them. Fertilizers for West Texas Some of the lighter soils of West Texas are low in phosphoric acid and potash, and fertilizers will probably be needed in this section of the State as time goes on, especially on irrigated soils. In fact, fertilizers have already been used with good results in some sections. Some of the soils of West Texas contain no more plant food than those of East Texas, but the roots of the plants penetrate deeper in dry sections and have more soil to feed upon than in humid sections so that the plant is able to secure more plant food than from the corresponding soil in the Eastern part of the State. When fertilizers are used in Texas west of the Blackland section, it is suggested that somewhat smaller amounts be tried than is recommended for East Texas, unless the land is irrigated. Also, unless the land is irrigated, care should be taken that the fertilizer is in the firm soil in which the plants grow, not in the loose earth, which is likely to dry out. 22 BULLETIN NO. 577, TEXAS AGRICULTURAL EXPERIMENT STATION Fertilizers for the Rio Grande Valley The soils of the lower Rio Grande Valley are generally well supplied with plant food, especially with potash. When the soils are new, they may contain an excess of nitrogen, and tend to produce a heavy growth of stalk and leaves, with deficiency of fruit. Superphosphate is perhaps the best fertilizer to use in such soils, where there is reason to believe an abundance of nitrogen is present. After having been under cultivation several years, these soils are likely to need nitrogen first, as the nitrogen is most readily exhausted. As it is desirable to avoid an excess of nitrogen, moderate quantities of nitrogen should be used at first. These soils are high in potash, and are less likely to need potash than the East Texas soils, which are lower in potash. How- ever, some potash may be used, especially as the cropping is heavy, but there is no need at present for the percentage of potash to exceed the percentage of nitrogen. Crop rotation with plants immune to nemitodes and resistant to root rot is highly important in vegetative production in the Rio Grande valley. Our suggestion at present for these virgin soils would be then to begin with superphosphate, if the vegetative growth is very heavy. In succeeding years 10-10-0, 16-20-0, 11-48-0 or combinations of these may be used or one of these may be used to begin with if vegetative growth is not excessive. In the course of time, when potash has been depleted by cropping, one would use such fertilizers as 6-12-6, 10-20-10, or 6-10-7. Fertilizers for the Gulf Coastal Plains There is considerable variation in the soils of the Gulf Coastal Plains. Some of the soils in the southern section are very sandy, and somewhat low in plant food. These should receive about the same fertilizer as the sandy lands of East Texas. Most of the soils are heavier and better sup- plied with plant food than the very sandy soils. The fertilizers suggested are the same for the corresponding soils of the Rio Grande Valley. The heavy black soils (The Lake Charles soils) at the Experiment Station at Angleton respond well to superphosphate and to applications of nitrogen and phosphoric acid on cotton and corn. Some of the soils of the Gulf Coastal Plains are poorly drained. They should be well drained and placed in good condition before any fertilizer is used, since applications of fertilizer will not remedy poor drainage. FERTILIZERS SUGGESTED FOR THE VARIOUS CROPS The suggestions given below represent the best present information for the use of fertilizers in Texas, and will be modified from time to time, as more experimental data are accumulated and further practical experience COMMERCIAL FERTILIZERS IN 1938-39 23 is secured. Home mixtures can of course be used in place of the factory mixed fertilizers here mentioned. Grades With the Same Ratios Where a fertilizer of a given ratio is suggested, a different grade with. the same ratio may be used, in such a quantity as to supply an equivalent amount of plant food. Where 4-12-4 is suggested, equivalent amounts of 3-10-3, or 5-15-5, may be used, as these all have the same ratio of plant food, 1-3-1. Where 4-8-4 is suggested, equivalent amounts of 6-12-6, or 10-20-10, may be used, as they have the same ratio of plant food, 1-2-1. Alfalfa For soil recently put in alfalfa, use 200 to 400 pounds per acre of super- phosphate. For soil in cultivation six years or longer (best to rotate), use 200 to 400 pounds of superphosphate, or 200 to 600 pounds of 0-12-4. Soils poor in lime should receive lime. (Bulletin 242.) Asparagus Apply 10 to 20 tons per acre of well-rotted manure and 500 to 800 pounds per acre of a 4-12-4 or 6-12-6 fertilizer when setting out the plants. Manure alone has given good results at both Balmorhea and Iowa Park. If the manure is not available, 600 to 900 pounds per acre of the fertilizer could be used. Every spring apply 400 to 600 pounds of 6-12-6 or 4-8-4. Just before the cutting season is over, or soon after, apply 200 to 400 pounds of 42-8-4 or 6-12-6. Two top dressings of nitrate of soda, 100 pounds per acre each, applied in the spring, would also be advisable in many cases. Beans (garden) and Peas (garden or English) An application of 300 to 500 pounds per acre of a 6-10-7 or 6-12-6- fer- tilizer is suggested, except in the lower Rio Grande Valley, where the use of 150 to 300 pounds per acre of 11-48-0 is suggested. Beets, Carrots, Turnips, and Radishes From 300 to 700 pounds per acre of 6-12-6 or 5-15-5 are suggested for East Texas and 16-20-0, 11-48-0, or 5-15-0 for the clay loam soils of the Rio Grande Valley and Gulf Coast. Broccoli, Cabbage, Cauliflower, Mustard, and Spinach From 300 to 700 pounds per acre of 6-12-6 or 5-15-5 may be used, supple- mented by three top dressings of 50 to 100 pounds of nitrate of soda or sul- phate of ammonia or other fertilizer containing only nitrogen, ten days 24 BULLETIN NO. 577, TEXAS AGRICULTURAL EYPEfiIMENT STATION or two weeks apart, beginning when the plants have begun to make a good growth. Excessive application of nitrogen and too rapid growth will impair the shipping quality. The nitrate of soda or sulphate of ammonia should be‘ sprinkled along the row, three or four inches from the plants, or applied broadcast after the dew has dried off or applied just before cultivation. In the Rio Grande Valley, 200 to 400 pounds per acre of l6~20-0 or 10-20-0 may be used. Com For loam or clay soils with clay or sandy clay subsoils, such- as Susque- hanna, Kirvin, Orangeburg, or similar soils, with legume rotations, use 200 to 300 pounds per acre of 4-8-4, 6-8-4, m‘ 4-10-0. For loam or clay soils with clay or sanxllyr clay subsoils, without legume rotation, in cultivation eleven years or nmore, use 200 to 300 pounds per acre of 4-8-4, 6-8-4, or 4-10-0. For deep sandy soil, use 200 to 30191 emails of 4-12-4. This is not a, gond ‘ corn soil. For land which produces a heavy stazlllk, but does not fruit well‘, use 213D jpounds of 20 per cent" superphosphate. For black waxy land (Houston black ch37); or hwvy limestone land ‘of Central Texas, a systematic rotation: it: needed first. Fertilizers ame- lmcertain, A trial may be made of 200i to» 41001 pounds per acre of 44040» or 100 pounds of 16-20-0. Side dressing: Corn may frequentiy use» to» advantage a side dressing of 100 pounds or more of nitrate of soda, sulpham of ammonia, or othem-soluhlie nitrate, applied at the side of the rows when the com is knee high, especial- ly when unfertilized corn follows crops tlint were previously well fertilized, or when a fertilizer low in nitrogen is used. Land fertilized the previous season: corn follows cotton that has been well fertilized the previous season, for example with a 4-8i-4, or 4-12-4 fertilizer at the rate of 300 to 400 pounds or more per acre, apply 100 pounds of nitrate of soda, sulphate of ammonia, or a synthetic nitrogen product before planting‘ or as a side dressing when the corn is 12 to 24 inches high. Corn Although corn responds to applications of fertilizers on most of the soils in the eastern part of the state, according to the Division of Agronomy of this Experiment Station, usually the use of fertilizers on corn has not been profitable perhaps because corn has a low value per acre. Where, however, COMMERCIAL'FERTILIZERS IN 1938-39 25 corn follows a well-fertilized crop, as cotton, tomatoes, or potatoes, the use of 100 pounds per acre of nitrate of soda or sulphate of ammonia has given good results. Cotton The sandy soils in the eastern and northeastern parts of the state general- ly need a complete fertilizer for cotton, according to the results of field ex- periments conducted by the Division of Agronomy. On the sandy loam soils with clay or sandy clay subsoils, such as the Kirvin, Bowie, Nacogdoches and similar soils, the use of 300 to 400 pounds per acre of a 4-8-4, 6-8-4, or 6-10-7 fertilizer or a fertilizer such as 6-12-6 with similar ratios and amounts of plant food is recommended. (See Bulletin 469.) The Lufkin soils, which have heavy, plastic clay subsoils, need a fer- tilizer with a high proportion of phosphate. According to the results obtain- ed in the Division of Agronomy on the Lufkin fine sandy loam at College Station, the application of 300 to 400 pounds of a 4-12-4 fertilizer or a fertilizer supplying equivalent amounts and ratios of plant food is recom- mended. The dark colored prairie soils in the humid part of the Gulf Coast Prairie, consisting largely of the Lake Charles soils, are first in need of phosphate and then in nitrogen. Field experiments on the Lake Charles clay loam at Angleton have shown that use of 300 to 600 pounds per acre of a 4-8-4 or 6-10-7 fertilizer is good fertilizer practice for cotton on this soil. Fer- tilizers with similar ratios such as 6-12-6 may be used. Moderate amounts of fertilizer without potash as 4-10-0 and. 16-20-0 also should give good results. Although experiments with fertilizers on cotton throughout the Blackland Prairie have shown some response to applications of nitrogen and phos- phate, fertilizers in general have not been profitable on these soils. Those who wish to try fertilizers could use 200 to 300 pounds per acre of 4-10-0 or 6-8-4 or 100 to 200 pounds of 16-20-0’. (Recommendations by Dr. Rey- nolds.) On land which produces an excessive stalk, and does not fruit well, which is chiefly bottom land, from 200 to 400 pounds of 18 per cent or 20 per cent superphosphate may be used. Nitrate of soda, sulphate of ammonia, or other nitrogenous fertilizer applied early at the rate of 100 to 200 pounds per acre sometimes give good results on bottom lands which pro- duce a moderately sized stalk. In the Rio Grande Valley, 200 to 300 pounds of 16-20-0 or 10-20-0 may be tried. In regions where the rainfall is sufficient, cotton may use to ad- vantage a top dressing of 100 pounds of nitrate of soda, sulphate of am- monia, applied along the rows at the time of chopping provided that the soil is well supplied with phosphoric acid and potash, either naturally or by use of a fertilizer low in nitrogen but containing phosphate and potash. 26 BULLETIN NO. 5T7, TEXAS AGRICULTURAL EXPERIMENT STATION Cantaloupes, Cucumbers, Squash, or Watermelons On sandy loam soils, 200 to 500 pounds per acre of 4-12-4 or 6-12-6 or 4-8-6 may be used. In southwest Texas, 300 to 400 pounds of 10-20-10 is suggested. An excess of nitrogen will produce a heavy growth of vine, but a deficiency of fruit. The remedy is to use more phosphoric acid or less nitrogen. Well-rotted manure should always be used with melons, if possible. Eggplant, Okra, and Peppers An application of 300 to 700 pounds per acre of 6-12-6 or 4-8-6 is sug- gested for trial. In the Rio Grande Valley, 200 to 300 pounds of 16-20-0 or 10-20-0 or 10-20-10 may be tried. Figs Recommendations for fertilizers for figs depend upon the nature of the soil and the size of the trees. On the heavy black prairie soils at Angleton, phosphoric acid gave a slight increase in yield, while nitrogen and potash gave no appreciable increase in yield of figs. An application of 200 pounds per acre of superphosphate is suggested for such soils. Figs seem to do best on a soil containing lime. For small trees on heavy black soil, 200 to 300 pounds to the acre of 4-10-0 is suggested. As the trees grow larger, the quantity of fertilizer may be increased to 600 to 1,000 pounds to the acre, or a 16-20-0 fertilizer may be used in smaller amounts. The fertilizer should be applied in the spring after danger of frost is past, and harrowed in. Weeds should be kept down, especially around young trees; otherwise, the fertilizer may help weeds to grow and thereby hold back the trees. Where a heavy crop. o.f winter clover is turned under, the amount of nitrogen needed in commercial fertilizers is low. Grapefruit or Orange Trees According to Bulletin 145 of the California Agricultural Experiment Sta- tion, nitrogen is the chief plant food needed in California, and is best supplied in well-rotted manure. A 16-20-0, 10-10-0, or 11-48-0 fertilizer may be used on Lower Valley soils, which are high in potash, sulphate of ammonia, nitrate of soda, or other nitrogenous fertilizer alone may be used. On soils low in potash, a 10-20-10 may be desirable. Bearing trees ten years old may each receive 10 to 20 pounds of fertilizer per tree each year. The soils on which citrus fruit are grown in Texas are generally higher in potash than in either phosphoric acid or nitrogen, and there appears no good reason at present to recommend fertilizers high in potash for most of these soils. COMMERCIAL FERTILIZERS IN 1938-39 N.‘ —) Onions The use of 600 to 1,200 pounds per acre of 6-12-6, 6-8-4, 5-15-5, or 6-10-7 is suggested. Under irrigation, the 6-12-6 fertilizer may be used at rates varying from 600 to 900 pounds per acre except on new land, when 1,200 pounds per acre may be used. On some soils, especially in the heavier soil in the Winter Garden District, potash is not needed and 300 to 700 pounds per acre of 5-15-0 or 16-20-0 fertilizer may be used. (See Bulletin 524 and 561.) Superphosphate alone at the rate of 300 to 400 pounds per acre is used on good land. Peach or Plum Trees For loam soils with clay or sandy clay subsoils, such as Orangeburg, Susquehanna, or similar types, use 200 to 600 pounds per acre of 4-10-0 or 4-12-4. The fertilizer may also be applied to individual trees at the rate of 1 pound per inch of diameter of the tree at the beginning of the grow- ing season. When the trees are bearing, use, in addition, 200 pounds or more of 10-10-0, increasing the quantity as the trees grow older. Accord- ing to experiments made. in other states and observations on commercial orchards in Texas, nitrogen is the only element needed for complete crops of peaches. Nitrogen can be supplied by cyanamid or other nitrogenous fertilizers. For deep sandy soil, such as Norfolk sand, use 200 to 600 pounds of 4-12-4 or 4-8-4. Clay soils and bottom lands: Use 200 to 600 pounds of 4-10-0. Potatoes, Sweet Loam or sandy loam soils with clay or sandy loam subsoils: 300 to 600 pounds per acre of 4-12-4 or 6-12-6 may be used. Deep sandy soil: Use 200 to 500 pounds of 6-12-6 or 6-10-7. Excess of nitrogen will produce excessive growth of vine and deficiency of tubers. The use of manure is desirable in growing sweet potatoes, but heavy applications of barnyard manure produce conditions favorable for disease. Potatoes, Irish On loam or sandy soils, 300 to 700 pounds per acre of 6-12-6 or 4-12-4 or 4-8-6 is suggested. In East Texas 500 to 800 pounds of 4-8-4 or 6-8-4 may be used. In the Rio Grande Valley, 16-20-0 or 11-48-0 may give good results when used at the rate of 200 to 300 pounds per acre. On some soils, a 10-20-10 is needed. 28 BULLETIN NO. 577, TEXAS AGRICULTURAL EXPERIMENT STATION Rice Experiments conducted in the Beaumont Substation from 1915 to 1928 show that 100 pounds to the acre of sulphate of ammonia made the largest increase in yield and has been the most profitable treatment used (see Bulletin 398, Fertilizers for Rice in Texas). Since 1935 experiments show that 100 pounds of sulphate of ammonia plus 100 pounds of 20% superphosphate drilled in with seed gave decided increases in yield. An application of 100 pounds to the acre on new land and up to 200 pounds on old land is recommended. On some rice soils, 200 pounds per acre of 6-12-6 may be tried. Sorghum An application of 200 to 300 pounds per acre of 4-8-4, 6-8-4, or 4-10-0 is‘ suggested. In the Rio Grande Valley, sometimes an application of 200 or more pounds per acre of cyanamid is applied when sorghum residues are turned under in the fall, to hasten decomposition of the residue and to fer- tilize the succeeding crop. Strawberries An application of 400 to 600 pounds per acre of 4-8-4, 4-12-4, or 6-12-6 may be made at the same time of setting out the plants. In the spring, just before blossoming, an early application of the same fertilizer should be used in about the same quantity, put as near the row as convenient, and worked into the soil lightly. Another application in the fall is also desirable, to stimulate the growth of the plants in the cold season. Side dressings have not been found effective in the Winter Garden District of Southwestern Texas. One-half ounce of superphosphate applied on the roots at planting time has been found to be beneficial in the Rio Grande Valley and green or animal manures seem to be needed by strawberries. Tomatoes Loam soils with clay or sandy clay subsoils of East Texas, such as the Ruston, Kirvin, or Nacogdoches: If 400 to 600 pounds per acre is used, use 4-8-6 or 6-12-6; if 500 to 1,000 pounds, use 4-8-6, 4-8-4, 4-12-4 or 6-8-4. Less than 500 pounds of fertilizer may be supplemented by 100 to 200 pounds of nitrate of soda or sulphate of ammonia if there is no tendency to excessive growth of vine. Deep sandy soil, such as Norfolk sand: If 200 to 500 pounds per acre is used, use 4-8-6, or 4-8-4; if 500 to 1,000 pounds is used, use 6-8-4. Less than 500 pounds of fertilizer may be supplemented by 100 to 200 pounds of nitrate of soda or sulphate of ammonia if there is no tendency to excessive growth of vine. ........._...._.¢____V_... ............ . .... . COMMERCIAL FERTILIZERS IN 1938-39 29 Winter Garden and Rio Grande Valley: Superphosphate alone at the rate of 300 to 500 pounds per acre has been found to give good results. The 16-20-0, 5-15-0, or 11-48-O fertilizer at the rate of 200 to 400 pounds per acre or 11-48-0 at the rate of 150 to 250 pounds per acre is used by many valley growers. Land which produces an excessive vine: Use 200 to 400 pounds of super- phosphate, 18 per cent or 20 per cent. Vines which grow large and do not fruit may sometimes be caused to fruit well without fertilizer if the vines are properly pruned. According to New Hampshire Bulletin 28, excess of potash delays maturity of tomatoes, and phosphoric acid hastens maturity. Home Gardens and Flowers Home gardens frequently receive large quantities of manure, with little or no applications of phosphoric acid or potash. This results in unbalanced condition of the plant food in the soil, resulting in excessive growth of leaves and stems and insufficient fruit or flowers. The best fertilizer to apply when heavy applications of manure have been made would be 200 to 400 pounds per acre of superphosphate, or 0-12-4 fertilizer. If the rows are 2 feet apart, one pound to 50 feet of row is equal to about 400 pounds fer- tilizer per acre. Where applications of manure have been made only in moderate amounts, 4-12-4 or 6-12-6 would probably be satisfactory at the rate of about 2 pounds to 50 feet of row. If light applications of manure are made, or none at all, 4-8-4, 6-12-6, or 4-8-6 at the rate of 1% to 3 pounds to 50 feet of row would be suggested, and top dressings with nitrate of soda or sulphate of ammonia at the rate of lé pound to 50 feet of row might also be tried. The fertilizer is best placed in furrow in a narrow band about two inches from the seed or plants and on the same level or a little below. If placed in direct contact with either seed or plants or too near to them, it may cause injury. One pound of the fertilizer may be broadcast on an area of 25 square feet, that is, 5 feet long and 5 feet wide, and worked into the soil, for flowers, or vegetable gardens. Two teaspoonfuls to the quart of soil may be used for potting soil. For potted plants, one teaspoonful for each quart of soil may be put around just inside the rim of the pot, and thoroughly watered, every month. Too much fertilizer will injure the plants. Plants may be watered with a solution of 1 teaspoonful (heaping) of fertilizer to a quart of water. Shade Trees and Ornamental Shrubs Shade trees and ornamental shrubs are probably benefited by fertilizer, but few fertilizer experiments have been made on such plants. The fer- tilizer should be added in such a way as to aid in developing the deep roots. Plants with surface roots extensively developed are likely to suffer from insufficient water in dry weather, or even to die. Where serious drouths 30 BULLETIN NO. 577, TEXAS AGRICULTURAL EXPERIMENT STATION occur, the development of deep-feeding roots by trees and shrubs is ex- ceedingly important. If a complete fertilizer is used, it is well to put it down in holes 15 to 20 inches deep or deeper. The holes may be punched with a pointed iron bar 1/2 to 3%; inches in diameter and 24 inches long, with a bar about 12 inches long welded across the top to serve as a handle. Four holes, about one foot from the plant are sufficient for rose bushes or similar plants. The fertilizer for trees should be distributed in 15 to 24 holes around in a circle a little larger than the spread of the branches. The holes should be completely filled with the fertilizer. For large trees, more holes should be punched and filled with the fertilizer. Manure may be put down in the same way, but the holes must be larger. Sulphate of ammonia, nitrate of soda, or some other nitrogenous fertilizer, or a complete mixed fertilizer such as a 4-12-4, 6-12-6, or 4-8-4, may be used at the rate of about one-half pound for each inch in diameter of the tree or shrub. Sulphate of ammonia would probably be best on limestone soils or basic soils, such as those of the blackland prairie region, and west or south of it. East of the blacklands, especially on the sandy soils, a complete mixed fertilizer would probably be best, though a nitrogenous fertilizer might be sufficient. Some varieties of roses and some broad leaved evergreens such as Camellias and Azaleas do best in an acid soil, and do poorly in alkaline soils. Such soils need acidification by applications of sulphur. Lawns An application of either sulphate of ammonia, cottonseed meal, 4-12-4 or 4-8-4 fertilizer at the rate of one to 2 pounds per hundred square feet is suggested. The fertilizer should be applied in the spring evenly, when the grass is dry, and then wet down thoroughly with the hose. If the grass is wet when the fertilizer is applied, the fertilizer will stick to it and probably burn it. The fertilizer can be applied broadcast by hand but it is more readily applied by a special distributor, which runs as easily as a lawnmower. If the soil is sandy or deficient in humus, an application of dried sheep or goat manure or well-rotted barnyard manure is suggested at the rate of 100 pounds to 100 square feet. This manure should be applied in the late fall or early spring. SUMMARY This Bulletin contains a report of the Texas Fertilizer Control for 1938-39 and definitions of fertilizer terms as adopted by Association of Official Agricultural Chemists. An explanation of terms is given. Sales of fertilizer in Texas were 93,115 tons in 1938-39. They were 79,640 tons in 1937-38. The tonnage for other years is given. The tons reported do not include cottonseed meal sold as a feed but used as a fertilizer. COMMERCIAL FERTILIZERS IN 1938-39 31 The average selling prices and composition of the different kinds of fertilizer are given. Available phosphoric acid costs slightly less in 20 per cent super- phosphate than in 18 per cent. Kainit is an expensive source of potash, muriate of potash being much cheaper. Plant food costs less per pound in the more concentrated fertilizers than in less concentrated fertilizer, though the former costs more per ton. The grades of fertilizer to be sold next season are given. A table is given showing the relation of the guaranteed valuation to the valuation delivered by the various manufacturers. Analysis of 1,208 samples collected by the inspector are given. Suggestions are made for the use of commercial fertilizer. 32 BULLETIN NO. 577, TEXAS AGRICULTURAL EXPERIMENT STATION Table 8.
