acid 900 pounds 



Kainit, 12.5 per cent potash 300 pounds 



2,000 pounds 



This mixture is more concentrated than precedini^ ones on account 

 of the use of higher grade materials and will contain: available' phos- 

 phoric acid, 9.1 per cent; potasl^ 1.9 per cent; nitrogen, 3.7 per 

 cent (equal to ammonia, 4.5 per cent).

acid 960 pounds 



Muriate of potash, 50 per cent potash 80 pounds 



2,000 pounds 



This mixture, too, is more concentrated than the preceding ones 

 on account of the use of a high-grade potassic material, muriate of
