DERSBURG. 



W. BoAz. 



Gray loam zcith clay subsoil. 



This land has been cleared for 25 years. The preceding 

 crops were cotton. There was no damage from rust or shed- 

 ding, but about 10 cent damage from the cotton caterpillar. All 

 the fertlizers were profitable except those on plot 12. The com- 

 plete fertilizer on plot 10 afforded the largest profit, $7.48 per 

 acre, or 139 per cent profit on the cost of fertilizers. 



The average estimated increase of seed cotton per acre was 

 110 pounds for cotton seed meal; 186 pounds for acid phos- 

 phate and 40 pounds for kainit. 



Nitrate of soda applied June 20, was less effective than was 

 cotton seed meal. Kainit at the rate of 100 pounds per acre 

 was more effective than where it was applied at double this 

 rate. 



Increase of seed cotton per acre when cotton seed meal was added: 



To unfertilized plot 128 lbs. 



To acid phosphate plot 164 lbs. 



To kainit plot 108 lbs. 



To acid phosphate and kainit plot 38 lbs. 



Average increase with cotton seed meal 110 lbs. 



Increase of seed cotton per acre when acid phosphate was added: 



To unfertilized plot 168 lbs. 



To cotton seed meal plot 204 lbs.

To unfertilized plot 50 lbs. 



To cotton seed meal plot 30 lbs. 



To acid phosphate plot 102 lbs.
