Continued. 



IN 1906 AND 1908. 



IN "Old Field" and in Fields A and B. 



The average results for three years for Eield A show that the largest 

 profits came from the application containing three times the normal 

 quantity of nitrogen per acre, or 27 pounds, the average yield being 

 41,4 bushels of corn per acre and the profit $4.50 over the cost of ferti- 

 lizer, on the basis of corn alone, or $7.29 on the basis of corn and stover. 

 For two years on "Old" Field the largest profit was also from the ap- 

 plication containing three times the normal quantity of nitrogen, the 

 average yield of corn being 39.5 bushels per acre, which represents an 

 increase of 10.3 bushels. This increase, however, was not enough to 

 pay for the fertilizer. The applications on the basis of corn alone 

 show a loss of 34 cents, or 65 cents loss on the basis of corn and stover.
