taining lo per cent, ammonia ; lOO pounds muriate 

 of potash, containing 50 per cent, actual potash. 

 This will contain about 9 per cent, nitrogen, 6.4 

 per cent, available phosphoric acid, and 5 per cent, 

 potash. 



Or this formula may be used : 100 pounds 

 nitrate of soda, containing 17 per cent, ammonia, 

 or 14 per cent, nitrogen ; 500 pounds sulphate of 

 ammonia, containing 25 per cent, ammonia ; 400 

 pounds high-grade blood and bone, containing to 

 to II per cent, ammonia; 800 pounds high-grade 

 acid phosphate, containing 16 per cent, phosphoric 

 acid ; 200 pounds sulphate of potash, containing 50 

 per cent, potash. This will contain about 9 per 

 cent, nitrogen, 6.4 per cent, phosphoric acid, and 5 

 per cent, potash. 



For soils that are badly leached the potash con- 

 tent should be higher, and the following are sug- 

 gested : 600 pounds sulphate of ammonia, contain- 

 ing 25 per cent, ammonia ; 200 pounds high-grade 

 blood and bone, containing 10 or 11 per cent, am- 

 monia; 800 pounds dissolved bone, containing 2 to 

 3 per cent, ammonia, and 16 per cent, available 

 phosphoric acid ; 400 pounds muriate of potash, 

 containing 50 per cent, potash. This contains about 

 9.5 per cent, nitrogen, 6 per cent, available phos- 

 phoric acid, and 10 per cent, potash. 



Or this formula may be used : 500 pounds sul- 

 phate of ammonia, containing 25 per cent, ammonia ; 

 400 pounds high-grade blood and bone, containing 

 10 per cent, ammonia ; 700 pounds high-grade acid 

 phosphate, containing 16 per cent, phosphoric acid ;
