 FERTILIZER FORMULAS. 



THE object in the preparation of fertilizer formulas is 

 to show the kinds and amounts of materials to use. Any one 

 formula is not the best for all conditions; these vary as widely 

 as the soils and different methods of management.

Ground Bone 250 Ibs. 



Acid Phosphate 500 Ibs. 



Muriate of Potash 250 Ibs. 



Composition. Nitrogen, 1 per cent; Phosphoric Acid 

 (available), 7 per cent; Phosphoric Acid (total), 12 per 

 cent; Potash, 12.5 per cent. 



Application, 200 to 300 pounds per acre on manured 

 soils; 300 to 500 on medium soils without manure. For 

 forage corn or ensilage, the nitrogen should be increased.
