 Sandy loam ivith ycllozv clay subsoil. 



This land has been in cultivation for a considerable length of 

 time. There was no damage reported from rust or insect at- 

 tacks. The stand was poor, but each plot had an average num- 

 ber of plants. The most profitable complete fertilizer was that 

 applied to Plot 9, affording a profit of $4.16 per acre or 68 

 per cent on the investment in fertilizers. The most profitable 

 single fertilizer was acid phosphate, which gave a profit of 

 $2.72, or 172 per cent on the investment in fertilizer. The aver- 

 age estimated increase of seed cotton attributable to cotton seed 

 meal was 34 pounds; to acid phosphate 142 pounds, and to 

 kainit 46 pounds.
