Barbour County, 3 Miles North op Louisville. 

 By J. D. Veal, 1905. 



Gray, sandy soil, with stiffer gray suhsoil. 



This field had been long in cultivation. 



The season was wet; rust was severe and all yields were 

 small. Nitrogen afforded a larger increase than did phos- 

 phate or potash. The most profitable mixtures contained 

 cotton seed meal, mixed either with acid phosphate or with 

 kainit. 



The Year before, on the same or similar land, a complete 

 fertilizer was the most profitable. Both years cotton seed 

 meal and acid phosphate were needed. 



Tn 1904 kainit was profitably used, giving an average in- 

 crease of 100 pounds per acre, as compared with an average 

 increase of only 38 pounds in 1905.
