Next to lime, acid phosphate was the most important 

 fertilizer for peanuts on this soil in 1913; even when 

 used alone at the rate of 240 pounds per acre it in- 

 creased the yield by 322 pounds of dry peanuts, 

 affording a profit of ^fll.20 per acre. The average in- 

 crease due to 240 pounds acid phosphate per acre was 

 269 pounds of dry nuts per acre. 



Potash was also helpful, but to a less degree. The 

 average increase due to 200 pounds of kainit per acre 

 was 54 pounds of dry nuts per acre. 



1914. 



The largest net profit, •'^19.00 per acre, was again on 

 the ])lot fertilized with slacked lime, acid phosphate 

 and kainit. In this year lime was responsible for an 

 increase of 208 pounds of dry nuts, which at 4 cents 

 per pound, is a profit of $5.32 per acre, for the lime 

 alone, in addition to a profit of $13.68 per acre due to 

 the mixture of acid phosphate and kainit. 



Again acid phosphate was, next to lime, the most
