EXPERIMENT MADE BY J. A. LOGAX, 



Clanton, Chilton County. 

 Soil, Mulatto ani Sandy; Sub soil, Red Clay. 



It is clearly shown by the results of two years' experiments made 

 by Mr. Logan that his soil does not need potash. In 1891 plot 6 

 gave an increase over plot 9 of 112 pounds, and over plot No. 16 of 

 4:8 pounds; while in 1892 plot No. 6 gave 16 pounds more than plot 

 No. 9, and 8 pounds more than plot No. 16. 



These amounts are small but they are valuable facts, and show 

 that it is a waste of money to use potash on such soils, as the yield 

 of cotton is decreased. It should be stated here that cotton seed 

 meal contains some potash, is why the comparison is made between 

 plot No. 6 and plot No. 16. Floats with green cotton seed gave 

 better results for the two years than floats with nitrate of soda.
