a Loss. 



It was found that with every crop for which there were a suffi- 

 cient number of records to make tabulations, increasing amounts of 

 fertilizer resulted in regular and appreciable increases in yields. But 

 with every crop except sweet potatoes the increased yields were 

 obtained at a higher cost per unit of crop, with exceptions to be 

 noted, and at lower profits per acre. Thus the cost of corn varied 

 from 85 cents per bushel, with the least amount of fertilizer, to $1.03, 

 with the largest applications; the corn planted with peanuts cost 

 57 cents per bushel without fertilizer, which cost increased to 94 

 cents when the most fertilizer was applied. The profits per acre 

 decreased in even greater proportion than the cost per bushel 

 increased. 



Cotton to which the value of the fertilizers applied amounted to 

 less than $2 per acre cost 8.7 cents per pound of net lint to produce. 

 But with increasing amounts of fertilizer up to $8 per acre, the cost 

 increased to 10.1 cents per pound. Apparently, increasing the fer- 

 tilizer applications beyond $8 per acre reduced the cost below the 

 high points of the preceding groups. But the small number of 

 records for these highest applications renders the results unreliable 

 for the last two groups.
