Director Charles D. Woods, who prepared the above 

 formulas, makes the following statement in connection 

 therewith: "Corn is a crop that uses a large amount of 

 nitrogen. It is usually grown upon sod land or with farm 

 manure, or both. Indeed, it is doubtful if, under ordinary- 

 conditions, it would prove a profitable crop to be grown 

 on somewhat exhausted soil with commercial fertilizers 

 alone. . . . The first formula contains only about one- 

 sixth of the nitrogen needed to grow the crop. With a 

 good sod and especially with a liberal dressing of farm 

 manure, that will be all that is needed. The second and 

 third formulas carry more nitrogen. ..."
