and was all applied before planting, along with the phosphoric acid and 

 potash. 



As an average of the results of the three fields, the best paying results 

 were secured by dividing the nitrogen application. One-half was put 

 in as blood at planting together with all of the phosphoric acid and 

 potash, and reserving the remaining half of the nitrogen to be applied 

 as blood alongside the corn plants about July 1. In Field B, which is 

 probably the most uniform field, there was but little difference between 

 the profit per acre from the following carriers of nitrogen applied in the 

 ways indicated, with the phosphoric acid and potash put in at planting : 

 (1) By dividing the nitrogen application, putting one-half in as blood 

 at planting and the other half as nitrate alongside the rows about July 

 1; (2) by having all the nitrogen derived from nitrate of soda, applying 

 one-half at planting and the other half about July 1; and (3) by hav- 

 ing all the nitrogen supplied by blood, one-half going in at planting and 

 the other half as a side dressing about July 1.
