EXPERIMENT MADE BY Mr. Z. T. STROUD, 



Aberfoil, Bullock Coui^ty. 

 Soil, Light Gray; Sub-soil, Clay. 



It is clearly shown by the results of two year's experiments 

 by Mr. Stroud that his soil is different in the three main elements 

 of plant food as plot No. 9 give best results for two years. 



When floats with nitrogen are compared, floats with green 

 cotton seed give best results for the two years.
