c. All fodders, pasture grasses, a,nd hay are rich in j^otash, and our 

 farmers have devoted a large share of their land to the xjroduction of 

 these crops. 



6. The relative deficiency of j'Otash in so many soils, shoion now by 

 the results of the work of two seasons, I believe justifies the folloiving 

 general advice. 



• a. In breaking up sod la,nd for corn particularly that which is in 

 fair condition but which has been under ordinary farm management, 

 if fertilizers only are to be used apply those which are rich in potash. 

 Use materials which loill supply, 80 to 100 pounds of actual potash, 

 from 25 to 30 pounds of phosi)horic acid, and from 15 to 20 pounds 

 of nitrogen jjer acre. 



b. If a special corn fertilizer is to be used, apply only a moderate 

 quantity, say 400 to 500 pounds per acre, and use with it about 125 

 pounds of muriate of potash. It is believed this combination will pro- 

 duce as good a crop as 800 to 1000 pouyids of '•'■ corn fertilizer ; " and 

 it will cost considerably less. 



c. With ordinary barn-yard or stable manure for corn, use potash. 

 I would recommend using about four cords manure and one hundred 

 pounds of muriate of potash per acre. 



d. For fodder or ensilage corn, use either in fertilizers or with ma- 

 nures about one-fourth more potash than above recommended. 



e. In our experiments^ cdl fertilizers and manures have been apiplied 

 broad-cast and harrowed in, and I believe this is the best method. 



f Although I recognize the danger of giving empirical directions of 

 a genercd nature, the restdts of our work lead me to recommend with 

 considerable confidence any one of the following mixtures per acre for 

 corn. 



I. 

 Muriate of Potash, 175 lbs. 



Dissolved Bone Black, 175 '•'■ 



Nitrate of Soda, 100 '' 



II.
