Increase of seed cotton per acre when acid phosphate 

 was added : 

 To nnfertilized plot 128 lbs. 116 lbs. 



To cotton seed meal plot 90 lbs. —39 lbs. 



To kalnit plot 55 lbs. 112 lbs. 



To cotton seed meal and kainit plot. 49 lbs. 53 lbs. 



Average increase with acid phos- 

 phate 81 lbs. 61 lbs. 



Increase of seed cotton per acre when kainit was 



added : 



To unfertilized plot —13 lbs. lOG lbs. 



To cotton seed meal plot — 1 lb. 3 lbs. 



To acid phosphate plot — 116 lbs. 102 lbs. 



To cotto^ seed meal and acid phos- 



fjhate plot — 12 lbs. 95 lbs. 



Average increase (or decrease[— ]) 



with kainit --5I 77 lbs. 



In both years cotton seed meal was the most import- 

 ant fertilizer for cotton; phosphate afforded a small 

 increase, possibly because of abnormal weather condi- 

 tions ; kainit was useless on upland in 1899 and scarcely 

 profitable in 1900 on second bottom land. 



EXPERIMENT MADE BY .J. W. FRENCH^ 3 MILES NORTH OF 



GORDO^ PICKENS COUNTY. 



This test was conducted in 1899 on gray upland, and 

 In 1900 on dark sandy upland, both having red subsoils, 

 rather retentive of water. The cotton experiment of 

 1899 was preceded by corn, that of 1900 by cotton. In 

 both cases the tests were on old fields, cleared of pines 

 and reclaimed four to seven years before the experi- 

 ments began. 



The former season Avas exceedingly dry; the latter, 

 ^^the most unfavorable ever known, first too wet and 

 then too dry." The stand was reported as excellent-
