moniated fertilizer," and tliree remaining unmanured. Acid phosphate 

 was used at the rate of 300 to 400 pounds per acre alone, 200 to 300 

 pounds with one other material, and 100 to 300 pounds in the complete 

 fertilizer; cotton-seed meal, 400 to 500 pounds alone, 100 to 250 pounds 

 with one other material, and 100 to 200 pounds in the complete fertili- 

 zer; and kainit at the rate of 300 to 400 pounds alone, 150 to 250 with 

 one other material, and 50 to 200 pounds in the comj^lete fertilizer. The 

 directions sent out by the station were in general not closely followed. 

 The number and width of rows, the spaces between the plats, and the 

 area for which the results were calculated, varied widely. The ex- 

 perimental fields selected seemed on the whole to be tolerably even 

 in fertility. The season was very unfavorable for all crops, a frost in 

 October reducing the cotton crop by one third or one half and in some 

 cases as much as two thirds ; while corn, except on the lowlands, was 

 badly damaged. The fertilizers applied, yields, and increased yield over 

 unfertilized plats are tabulated for each experiment. 



Results of experiments icitli corn. — " The result is more favorable than 

 for 1888. Then the applications, with but few exceptions, proved unre- 

 muuerative. For this season a much larger number yielded good re- 

 turns. * * * Without exception, cotton seed meal, in both large 

 and small applications, increased the yield materially and proved remun- 

 erative. This effect extended to the combination of meal with other 

 ingredients. Acid phosphate alone, in all cases except one, only slightly 

 increased the yield, and proved unremuuerative. In combination with 

 meal the result was better, but with kainit the yield was not sufficient 

 to be remunerative. Kainit alone was generally quite unsatisfactory 

 in both large and small applications. The complete fertilizers, repre- 

 sented by Nos. 3 and 13 [200 or 300 pounds acid phosphate, 100 or 150 

 pounds cotton seed meal, and 50 or 70 pounds of kainit], in the main 

 proved satisfactory." 



Results of experiments loitli cotton. — The author believes that the fol- 

 lowing deductions from this year's results may be safely made : 



Applications of fertilizing material, notwithstanding the wet season and other difiS- 

 culties, were profitable, with but few exceptions. Acid phosphate used alone has 

 I)roved profitable in a majority of cases, which agrees with the result of last year. 

 Cotton-seed meal used alone has proved remunerative in both large and small applica- 

 tions, verifying the favorable impression made last year. The experience with kainit 

 this year has been th^same as last, and verifies the estimate placed upon it at that 

 time. It has proved unprofitable. Stable manure has proved beneficial. Twenty 

 two-horse loads per acre have increased the yield materially; but, considering the 

 cost, the smaller application of 10 two-horse loads per acre is more remunerative. 



* * * [As iu 18S8] next to stable manure the best a2)plication for this season 

 for the average soil appears to be a combination of the three ingredients — available 

 phosphoric acid, nitrogen (or ammonia), and potash. The best proportion of these 

 ingredients was 200 pounds acid phosphate, 100 pounds cotton-seed meal, and 50 

 pounds kainit to the acre of average soil. Where the land is poor this application 

 per acre might well be increased in the same proportion.
