EXPERIMENT MADE BY[Me. DAN GILLIS, 



In Charge of Southeast Alabama Experiment tation, Abbe 



viLLE, Henry County. 



Soil, Sandy ; Sub-soil, Sand and Clay Mixed. 



It is clearly shown by the results of this experiment that the soil 

 on the Southeast Alabama Experiment Station is deficient in the three 

 main elements of plant food. In 1891 plot No. 9 gives largest 

 yield of any except Plot No. 15 — stable manure — and gives an in- 

 creased yield over average of no manure, of 735 pounds per acre. 

 While in 1892 the increase is not so large (414 pounds), yet the facts 

 indicate best results from the use of complete fertilizer. Floats 

 with green cotton seed give better results for the two years than 

 floats with nitrate of soda.
