Clay loam iv'itli red subsoil. 



This land has been cultivated for 75 or more years. The 

 preceding- crop was cotton. The stand was fairly good. No 

 damage by insects were reported. Cotton seed meal gave the 

 most profitable result. Acid phosphate and kainit did not pay. 

 The average increase for cotton seed meal was 173 pounds of 

 seed cotton per acre, against 2 pounds for acid phosphate, and 

 a loss of 20 pounds where kainit was used. Cotton seed meal 

 gave a profit of $3.66 per acre, or 122 per cent profit on the in- 

 vestment in fertilizers. On the whole, there was little profit 

 from fertilizers in this experiment.
