The tonnage sold increased from 79,863 tons in 1926-27 to 187,215 tons in 1928-29, then decreased to 30,843 tons in 1932-33. Sales gradually increased to 84,938 tons in 1936-37, then decreased slightly. Tag sales by months are largest in January, February, and March. Shipments of fertilizer are largest in Feb- ruary, March, and April, with the heaviest movement in March. Fertilizer sales by counties is shown by a table and a map. The largest consumption is in the northeastern part of the State. The tonnage of various grades is given for the past 12 years’, and the tonnage of various goods given for a few selected counties. The selling price of the various grades is given for the past 12 years, and the relation between the selling price and valuations is shown. The approximate cost of nitrogen, phosphoric acid, and potash in cents per pound is given for the past 12 years. The sales of fertilizer in the spring are related to the price of cotton in the preceding fall and winter.

S. Fraps, State Chemist, and T. L. Ogier, Associate State Chemist A Texas fertilizer law was first passed in 1899 and amended in 1911. Since then the law has not been changed. Various statistics concerning fertilizer have been collected during this period of time. Fertilizer sta- tistics from 1905-6 to 1925-6 have been published in Bulletin 350 of this Station. The object of the present Bulletin is to present statistics which have been collected for the most part from 1926 to 1938. Fertilizer Control Bulletins Since 1899, 37 Fertilizer Control bulletins have been published. A list of Fertilizer Control bulletins is given in Table 1. This list does not in- clude research bulletins. These bulletins contain not only information re- garding the operation of the fertilizer law, but also suggestions regarding the use of fertilizer and definition of fertilizer terms. Table 1.

This is larger than the sales actually made, as some of the tags are not used, and the tax tags are not redeemable. The sales increased from 13,500 tons in 1905 to 77,400 tons in 1914, although there was a drop to 46,000 in 1911-12. In 1914-15, the first year of the World War, the sales dropped to 17,500 tons, but they gradually increased until in 1918-19, when there was a decrease, followed by an increase in 1919-20. In 1920-21, the sales reached the lowest point since 6 BULLETIN NO. 572, TEXAS AGRICULTURAL EXPERIMENT STATION 1905-6, 14,850 tons, because of the depression after the World War; but sales then increased rapidly to 126,180 tons in 1923-24. There was a de- crease in sales in 1924-25, followed by a decided increase in 1925-26, then another decrease in 1926-27. Sales then increased rapidly to 187,215 tons in 1928-29, the largest tonnage yet sold. Sales then decreased rapidly to 30,843 tons in 1932-33. Since that date sales increased gradually to 84,938 tons in 1936-37, and then decreased slightly. Table 3 shows fertilizer tonnage based on tag sales for some other states. Arkansas sales are the lowest, with Texas next and Louisiana sales much larger than those of Texas. In spite of the great area of Texas, fertilizer sales are small compared with those of North Carolina, Georgia, and Alabama; but fertilizers have been used in these states much longer than in Texas.

Table 5 contains the same tag sales expressed in percentage of the total sales for the year. The largest tag sales occur in January, February, and March, while the heaviest shipments are made in February, March, and April. About 70 percent of the total is shipped these three months. Table 6 contains shipment in tons, as reported monthly by manu- facturers, expressed in percentage of the total sales. FERTILIZER STATISTICS FOR TEXAS, 1926-1938 7 The tonnage sold by manufacturers shows somewhat different results from that shown by tag sales. Since tag sales are made before actual shipments of fertilizer take place, purchases of tags in the early part of the season are used in shipments made later. The two may be com- pared by means of the last columns in Table 5 and Table 6. Table 4.

Table 7 contains sales by counties from 1926-27 through 1937-38 tabu- lated from sales reports mentioned above. This tabulation gives an idea of the relative use of fertilizers in the various counties of the State, but it is not strictly correct. Fertilizers shipped into one county may be used in an adjoining county. The reports of the manufacturers are sometimes not complete, and shipments are sometimes reported twice. The errors are, of course, not uniformly distributed. Table 8 gives the sales by counties in order of tonnage for 1937-8, be- ginning with the county having the largest sales. The table includes all counties to which over 500 tons were shipped. Table 7.

The cottonseed meal included is that tagged with fertilizer tags. Considerable amounts of cottonseed meal tagged with feed tags are, no doubt, used for fertilizer in Texas, but there is no way of finding out how much. FERTILIZER STATISTICS FOR TEXAS, 1926-1938 13 Some of the grades of fertilizer sold in 1926-27 are still being sold, but a number of grades sold in 1937-38 were not sold at that time. The sale of superphosphate has decreased from 28 percent of total tonnage sold in 1926-27 to about 9 percent of total tonnage sold in 1937-38. Grades have been tried experimentally and then dropped. The sale of 3-10-3 fertilizer decreased from 20 percent in 1928-29 to about 4 percent in 1937-38, while the sale of 4-8-4 fertilizer increased from 12 percent to 23 percent. A number of grades of more concentrated fertilizers are gradually becoming popular, and the sale of such fertilizers may increase from year to year. The tendency is toward higher grades of fertilizer. Thus 12-% and 14% kainit have been replaced by 20% kainit and 30% manure salts. The 16% sulperphosphate has not been sold since 1929; 18 and 20% superphosphate are being sold in place of it. The 2-10-2 was a heavy seller in 1928 and previous years but was discontinued in 1929, being replaced by higher grades. Table 9 reflects some of the experimenting being done with grades, as some appear and disappear. Table 9.

Grades of Fertilizer Used by Counties Table 10 contains, for a few selected counties, in which large quantities of fertilizer are used, the tonnage used of the different grades of fer- tilizer. Cass, Cherokee, and Harrison counties represent the cotton and tomato section in the northeastern part of the State. Jefferson in the southeastern part of the State grows rice as well as other crops. Cameron in South Texas and Webb County in the Southwest use fertilizer chiefly for vegetable and citrus fruits. El Paso County represents the far West. The 4-8-4 grade of fertilizer leads in Cass, Cherokee, and Harrison coun- ties, northeastern part of the State, where most of it is probably used for cotton with some vegetables. The 4-10-0, bone meal, and superphosphate lead in Jefferson County, where fertilizer is used chiefly for rice. In FERTILIZER STATISTICS FOR TEXAS, 1926-1938 15 Cameron County, 32% superphosphate and 16-20-0 lead. Webb County uses 6-12-6 and 6-8-4 most extensively. El Paso County uses 16-20-0 and 11-48-0. The concentrated grades of fertilizer are used in the western counties more than the other grades, chiefly for onions, spinach, and other vegetables. Table 10.

Valuations and Selling Prices Table 11 contains the assumed valuations in cents per pound for nitrogen, phosphoric acid, and potash from 1926-27 through 1937-38. Since 1932-33 the valuation for nitrogen has been 46 percent less than it was from 1926-27 through 1929-30. The lower cost of nitrogen is no doubt due to the development of chemical methods of fixing nitrogen. The valuations for phosphoric acid have not changed appreciably, while potash is a little lower than in 1926-27. 16 BULLETIN NO. 572, TEXAS AGRICULTURAL EXPERIMENT STATION Table 11.

FERTILIZER STATISTICS FOR TEXAS, 1926-1938 21 Table 14 contains the approximate cost of nitrogen, phosphoric acid, and potash in cents per pound from 1926-27 through 1937-38 for some of the largest selling grades. The cost of nitrogen was highest in the 3-10-3 grade and lowest in cyanamid. The cost of phosphoric acid was highest in the 3-10-3 grade and lowest in the 6-12-6 grade. The cost of potash was highest in the 3-10-3 grade and lowest in the 6-12-6 grade. The cost prices are calculated on the assumption that Table 12 contains the correct ratio of prices, and that Table 11 contains correct prices. These cost prices are, of course, only approximate. Relation of Fertilizer Sales to Price of Cotton The sales of fertilizer in Texas have shown a tendency to increase as the State grows older, the land remains longer in cultivation, and the need for fertilizer becomes greater on account of decreased producing power of some of the soils. Familiarity with fertilizers also encourages their use. There are fluctuations in the amounts of fertilizer used from year to year, and there seems to be some relation between the amount of fertilizer used and the price at which cotton is selling previous to the planting season. Table 15 contains the sales of fertilizer in Texas and the New Orleans prices of middling cotton on the first sale day of the month. These prices were kindly furnished by Mr. Henry Plauche, Secretary of New Orleans Cotton Exchange. The prices in each list begin with the year first given and continue into January of the next year, as the fertilizer season begins September 1. It is also desirable to estimate the relation as early as possible. The figures show that there is a relation between the prices of cotton during the fall and winter and the fertilizer sales from September 1 to August 31. This relation is to be expected. It is also to be expected that the relation will not be close, as there are other important factors which Table 15.

The relations for the years 1905-1926 were given in Bulletin 350; the correlation between the selling price of cotton and the sale of fertilizer following from 1905 to 1926 was .50 i .11 for October, .58 i .10 for November, .55 i .10 for December, and .55 i .10 for January. The correlation coefficients for the data in Table 15 for 1926 to 1938 were calculated with the following results: Correlation Coefficients Fertilizer Sales and Cotton Price October cotton + .86 i .05 December cotton + .91 i .08 November cotton + .90 i .04 January cotton + .89 i .04 The relation between the price of cotton and the sale of fertilizer in the above table is expressed by the following equation: Estimated sales in tons equals 8400 times the November price of cotton minus 20,000 tons. The relations of past years are not necessarily followed in future years, since conditions may change; so any attempts to use this equation for the purpose of predicting the sales of fertilizer must be recognized as extremely tentative. SUMMARY AND CONCLUSIONS The Texas fertilizer law was passed in 1899 and amended in 1911. Fertilizer sales increased to 187,215 tons in 1928-29, but declined to 30,843 tons in 1932-33 and increased to 84,938 tons in 1936-37. Tag sales expressed as tons of fertilizer are given by years and months. The percentage of sales is also given. The heaviest sales occur in March. Total sales by counties since 1925-26 are given for each year, with a map for 1937-38. The counties in northeastern part of the State use the most fertilizer. Sales by grades in some counties for 1938 are given. The tonnage of grades sold since 1925-26 is shown. The number of grades has decreased considerably. The sale of superphosphate decreased from 28 percent of the total tonnage in 1926-27 to about 9 percent of the total tonnage in 1937-38. More concentrated fertilizers are being used to a greater extent. A large number of grades are no longer being sold. The average selling prices of the different grades are given for the past 12 years. Tables relating to valuations and prices are given. There is a relation between the price of cotton in the preceding fall and winter and the sale of fertilizer in the following spring.
