Experiment Made by J. W. Wyatt^ Five Miles East of 



MONTEVALLO, ShELBY CoUNTY. 



Dark, reddish, sandy upland with red clay siibsoil. 



This field had been cleared of its second growth of timber 

 for about fifteen vears, and for about ten years in succes- 

 sion had been planted in cotton. 



The original growth is reported to have been oak, hickory^ 

 chestnut and dogwood, and the second growth springing- 

 up when the land was thrown out of cultivation after the- 

 civil war was short leaf pine and sumac. No mention is, 

 made of rust. 



The complete fertilizer raised the 3ield to more than a 

 bale per acre, an increase of 464 pounds. The complete fer- 

 tilizer with 100 pounds of kainit was more profitable than= 

 the one with a larger amount of kainit, the former afford- 

 ing a profit of |7.23 per acre after paying for fertilizer anr^ 

 picking and ginning of the increase^
