drought, which reduced the yield to about half a crop, 

 and which probably makes the experiment nearly value- 

 less as an indication of the needs of the cotton plant on 

 this soil in normal seasons. 



Under the conditions of this test no fertilizer was very 

 effective, though the increase with cotton seed meal was 

 sufficient to pay a small profit. 



Mr. Bevill conducted an experiment in 1898 on w^hat 

 appeared to be similar soil. In that year cotton seed 

 meal gave a large increase in yield, phosphate a smaller 

 though profitable increment, and kainit an increase 

 barely sufficient to afford a small profit. In 1898 as wel 1 

 as in 1899 unfavorable weather vitiated the experiment, 

 and it is doubtful whether the results for either vear 

 show the full effect that any of the three fertilizers 

 would exert in normal seasons. 



Increase of seed cotton per acre when cotton seed meal 

 was added : 



To unfertilized plot 56 lbs. 



To acid phosphate plot 178 lbs. 



To kainit plot 114 lbs. 



To acid phosphate and kainit plot 172 lbs. 



Average increase with cotton seed meal 130 lbs. 



Increase of seed cotton per acre when acid phosphate 

 was added : 



To unfertilized plot 32 lbs. 



To cotton seed meal plot 154 lbs. 



T o kainit plot — 25 lbs. 



To cotton seed meal and kainit plot 33 lbs. 



Average increase with acid phosphate ,49 lbs.
