EXPERIMENT MADE BY S. A. PRUITT, 

 Chess, Pike County. 

 Soil, Light Sandy; Suh-soil, Bed and Yellow Sandy. 

 The best results in this experiment for the two years are from 

 plot 16 — cotton seed meal with acid phosphate. Plot No. 9, com- 

 plete fertilizer, gave a marked increase over plot No. 6 for each 

 year, and the indications are that the soil is deficient in the three 

 main elements of plant food. Floats with green cotton seed give a 

 decided increase over floats with nitrate of soda for the two years
