FLOREXCE. 



\\'. R. Cox. 



Clay soil with red clay subsoil. 



This land has been cleared for 65 years. The preceding" crop 

 was cotton. 'Jhere was no damage reported from rust. The 

 cotton caterpillar destroyed about 23}/^ per cent of the entire 

 croj). The stand was good, except a few missing plants in Plot 

 1. Cla\- from the ditch was thrown on Plot 12, which seemed 

 to decrease the yicUl on that plot. 



It appears from this experiment that this land docs not need 

 kainit. Cotton seed meal and acid phosphate were profit- 

 able when used alone or in pairs. The highest estimated in- 

 creased yield of seed cotton per acre was 372 pounds on Plot 

 10. A ])rofit 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 pounds for cotton seed meal ; 129 pounds for acid phos- 

 phate ; and an average loss of 18 pounds per acre for kainit. 

 - Cotton seed meal was more effective than nitrate of soda.

To unfertilized plot 136 lbs. 



To acid phospha e plot 148 lbs. 



To kainit plot 140 lbs. 



To acid phosphate and kainit plot 306 lbs. 



Average increase with cotton seed meal 183 lbs». 



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



To unfertilized plot 104 lbs. 



To cotton seed meal plot. 116 lbs. 



To kainit plot 64 lbs. 



To cotton seed meal and kainit plo: 230 lbs. 



Average increase with acid phosphate 129 lbs. 



Increase of seed cotton per acre when kainit was added: 



To unfertilized plot —38 lbs. 



To cotton seed meal plot — 34 lbs. 



To acid phosphate plot — 78 lbs. 



To cotton seed meal and acid phosphate plot 80 lbs.
