The chief object of these local fertilizer experiments or soil tests has been to ascertain the best fertilizer or combination of fertilizers for cotton, growing on each of the principal soils of the northern half of Alabama. The results recorded in this bulletin were obtained in fertilizer experiments conducted with the funds provided by the Legislature of Alabama in February, 1911. This bulletin deals only with fertilizer experiments carried to a conclusion in 1911 in the northern half of the State. For convenience the counties grouped together in this bulletin are those lying wholly north of the Central Prairie or Lime Region Central Alabama. The results of fertilizer experiments made in the counties lying wholly or partly south of the Central Prairie Region appeared in Bulletin No. 160, issued by this Station in December, 1911. Local fertilizer tests constitute only one of many lines of experiments instituted in 1911 by the Alabama Experiment Station with the support of state funds, none of which were available for experimental work prior to the present year. Local fertilizer experiments as now conducted are made on the farms of farmers especially recommended as being men likely to take the necessary pains to secure accurate results. These experiments, located all. over the State, are visited and by representatives of the Experiment Station, who are expected to select and measure the land, make periodic visits, and take notes on the progress and results of the experiment, and, so far as practicable, assist" in harvesting the crop: However, the late date at which this work was begun in 1911, the fact that many farmers had already fertilized their most suitable land before being invited to make these experiments, and the necessary delay in securing the services of the men ,of -supervised rere to supervise these experiments, resulted in many cases in the selection of land and of locations which later proved not entirely satisfactory. It is expected that in future the percentage of conclusive and satisfactory experiments will be larger. However, no increase can be made in the total number of fertilizer experiments. Small lots of carefully weighed and mixed fertilizers were supplied to each experimenter. Detailed instructions as to how to conduct the experiment and blank forms for reportlug- results wrere also furnished. Representatives of the inspected from one to three times all of the experiments here published except one. The following list gives the name and address of each experimenter who has reported the results of fertilizer experiments made in 1911 in the part of the State indicated, togetber w\ithhe page of this bulletin where the results may be found. o tion Sta- COUNTY Bibb--- BibbBlount-Calhoun ---- POST OFFICE -- -Randolph - Centerville -Oneonto--- NAME M.

The directions sent to each experimenter stated that the land employed for this test should be level and uniform, not manured in recent years, not in cowpeas the preceding year, and that it should be representative of large soil areas in its vicinity. The need of perfect uniformity and standard treatment for all plots (except as to kind of fertilizer used) was emphasized. Fertilizers were applied in the usual manner-that is, drilled before planting) except nitrate of soda which wAas directed to be applied when the plants were 6 to 10 inches high. THE FERTILIZERS USED. The following prices are used, as representing approximately the average cash price in local markets during thelast few years: Per Ton. Acid phosphate (14 per cent. available)......$14.00 Cotton seed meal ......................... Kainit. .............................. Prices naturally vary in different localties. $30.00 $14.00 Any one can substitute the cost of fertilizers in his locality for the prices given above. In each experiment three plots were left unfertilized, these being plots 3, 7, and 11. When these yields differed widely the experiment was classed as inconclusive The increase on plots 4 to 6 is calculated on the assumption that the gradation in fertility is uniform from plots 3 to 7; likewise the increase is calculated for Plots 8 to 10 inclusive.* The following table shows what kind and amounts of fertilizers were used on certain plots; the number of pounds of nitrogen, phosphoric acid, and potash supplied per acre by each fertilizer mixture; and the percentage composition and cost per ton of each mixture, the latter being given in order that these mixtures may be readily compared with various brands of prepared guanos. *In other words instead of calculating the increase merely by subtracting the yields of any plot from the average yield of the three unfertilized plots (which would be incorrect and misleading unless all three unfertilized plots afforded practically the same yield), the following method is used as a means of making allowance for variations in the natural fertility of the different plots:(1). The difference between the yields of unfertilizedi plots 3 and 7, or between unfertilized plots 7 and 11 is divided by 4, because this difference must be distributed over the four intervening plots. (2). This quotient is then added to the yield of the poorest of this unfertilized pair, thus giving the corrected or calculated yield (if unfertilized), for the fertilized plot adjacent to the poorest unfertilized one. Similarly the yield of the poorest unfertilized plot is increased by twice and three times the above quotient as a means of calculating the corrected unfertilized yield on the plots occupying respectively second and third positions from the poorest unfertilized plot of the pair. (3) Now these calculated yields (if the plots were unfertilized) are subtracted in regular order from the corresponding actual yield, thus giving the most accurate measure known for the increase due to the fertilizer. .Pounds per acre of fertilizers, nitrogen, phosphoric acid, anc potash used and composition of each mixture.

This is old land, and has been long in cultivation. There was no material damage from rust or insect injuries. The most profitable fertilizer was cotton seed meal applied alone, which afforded a profit of $10.57, or 302 per cent profit on the investment in fertilizers. 217 pounds The average estimated increase of seed cottton per acre was for cotton seed meal. On the average there was a loss of 38 pounds for acid phosphate, and a gain of 92 pounds for kainit. Nitrate of soda applied June 20, was more effective than was cotton seed meal.

Plots 1, 3, 7, and .11 had poor stands. 10 There was no damage done by the cotton caterpillars. The complete fertilizers were all highly profitable, as was also a mixture of acid phosphate and kainit. The complete fertilizers with cotton seed meal gave larger profits than did the one with nitrate of soda. The average estimated increase of seed cotton per acre was 197 pounds for cotton seed meal; 378 pounds for acid phosphate; and 290 pounds for kainit.

Corn was the preceding crop. The land was turned with a one-horse plow and then subsoiled with a scooter. The stand was uniform. Cotton rust occurred on all plots and was estimated as reducing the yield one-third. There was nonontahle insect injury. Acid phosphate was the fertilizer chiefly needed, affording an average increase in seed cotton of 224 pounds per acre, as comspared with an increase of 88 pounds for cotton seed meal, and 46 a loss of 76 pounds from the use of kainit. Acid phosphate used alone gave a net profit of $9.44 per acre, or 562 per cent on the investment in fertilizers.

The cotton caterpillar destroyed about 3313 per cent of the entire crop. The stand was goodi, except a few missing plants in Plot 1. Clay from the ditch was thrown on Plot 12, vhich seemed to decrease the yield on that plot. It appears from this experiment that this land does not need kainit. Cotton seed meal and acid.phosphate were profitable when used alone or in pairs. The highest estimated increased yield of seed cotton per acre was 372 pounds on Plot 10. A profit of $6.59 per acre, or 122 per cent, was obtained on this plot. The average estimated increase of seed cotton per acre was 183 ponnds for'cotton seed meal; 129 ponnds for acid phosphate; and an average loss of 18 pounds per acre for kainit.

COLBERT COUNTY, 2 MILES EAST OF TUSCUMBIA. G. H. HARRIS. Dark clay loam, valley soil; red clay subsoil. This land has been in cultivation for a long time. The preceding crop was oats. There was no shedding or rust, but the cotton caterpillar damaged the crop about 60 per cent, rendering the results inconclusive. (See page 50.) The most profitable application was on Plot 12, affording a profit of $4.34, or 89 per cent on the cost of fertilizers. The average estimated increase of seed cotton per acre due 108 pounds for to the use of cotton seed meal was 69 acid phosphate; and a loss of 6 pounds for kainit.

T. Butler conducted an experiment on light red clay loam, with red clay subsoil. The results were inconclusive, partly because of injuries by the cotton caterpillar. See page 55. In MADISON COUNTY, 3 miles northwest of Huntsville, W. W. Fox conducted a fertilizer experiment on gray land with red clay subsoil. This proved inconclusive because of want of uniformity in the fertility of the land. Apparently MARION COUNTY, 6 MILES NORTHEAST OF GLEN the most profitable fertilizer was cotton seed meal. See page 55 ALLEN. W. P. LETSON. Dark sandy loam, red clay subsoil. This land has been cleared for 30 years. The preceding crop was cotton. There was no damage from rust or insect attacks. There was a perfect stand. The plots in this experiment were 1-acre each, instead of 8, as were the regular plots, but received the full amount of fertilizer. The yields were so irregular that no definite conclusion can be drawn, except that cotton seed meal and nitrate of soda were profitable.

J. D. WILLIAMS. Red loams, red clay subsoil. This land has been in cultivation for about 20 years. The preceding crop was oats. Considerable damage was done by rust on Plots 9 and 10, and slight damage was done by wilt. There was a nearly perfect stand. All of the complete fertilizers were profitable, as were all other plots where cotton seed meal was added. Cotton seed meal, when applied alone, gave a profit of $3.18 or 76 per cent on the investment. The average estimated increase of seed cotton per acre was 280 pounds for cotton seed meal; 91 pounds for acid phosphate; and 112 pounds for kainit. The plots in this experiment were only 12 -acre, instead of 1 acre as directed, making the rate of fertilization and hence the results cannot be compared with those of other experiments reported.
