COST OF FARMING OPERATIONS 



wheat and oats, and $2.30 for hay, or an 

 average of about $4.90 per acre for the four 

 crops. The interest on the capital invested 

 in operating this farm, exclusive of the land, 

 was estimated at $1.45 per acre. 



INFLUENCE OF YIELD UPON THE COST OF 



PRODUCTION 



The Illinois station has prepared a set of 

 estimates upon the cost of producing an 

 acre of maize, showing variations in cost 

 due to differences in yield. In these esti- 

 mates, instead of making a charge for the 

 actual cost of manure or fertilizer applied, 

 an estimate is made of the value of the plant 

 food removed.
