In such a mixture, 1.5 per cent is derived from nitrate of 

 soda, 1.5 per cent from sulfate of ammonia, 1 per cent from 

 cottonseed meal or fish, and 1 per cent from tankage. Blood 

 (16% NH3) could be substituted for tankage, in which case 

 125 pounds should be used in the mixture, with 125 pounds 

 of some inert material. 



If it is desired to use bonemeal as a source of phosphorus, 

 a 9-5-3 goods can be prepared as follows : 



Bonemeal (22% PA) ^7o NH3 840 Lbs.

Such a mixture would have its ammonia derived, 1 

 per cent from nitrate of soda, 1.5 per cent from sulfate 

 of ammonia, 1.5 per cent from bonemeal and 1 per cent 

 from cotton-seed meal or fish. All of the phosphoric acid 

 and half the ammonia in this mixture is only slowly avail- 

 able. 



If the phosphoric acid in such a mixture were derived 

 partly from acid phosphate and partly from bonemeal, it 

 would probably be a better fertilizer for pecans. Such a 

 mixture can be prepared as follows :
