The Bulletin. 67 



No. 7— 



Acid phosphate, 14 per cent phosphoric acid 9C0 pounds 



Fish scrap, 8.25 per cent nitrogen and 6.0 per cent phos- 

 phoric acid : 900 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 pot- 

 ash, and will contain: available phosphoric acid, 9.6 per cent; potash, 

 2.0 per cent; nitrogen, 4.0 per cent (equal to ammonia, 4.8 per cent). 



No. 8— 



Acid phosphate, 14 per cent phosphoric acid 950 pounds 



Cotton-seed meal, 6.59 per cent nitrogen, 2.5 per cent phos- 

 phoric acid and 1.5 per cent potash 1,015 pounds 



Muriate of potash, 50 per cent potash 35 pounds 



2,000 pounds 



This mixture will contain: available phosphoric acid, 7.9 per cent; 

 potash, 1.6 per cent; nitrogen, 3.3 per cent (equal to ammonia, 4.0 

 per cent). 



No. 9— 



Acid phosphate, 16 per cent phosphoric acid 900 pounds 



Cotton-seed meal, 6.59 per cent nitrogen, 2.5 per cent phos- 

 phoric acid and 1.5 per cent potash , 1,060 pounds 



Muriate of potash, 50 per cent potash 40 pounds 



2,000 pounds 



This mixture will contain : available phosphoric acid, 8.5 per cent ; 

 potash, 1.8 per cent; nitrogen, 3.5 per cent (equal to ammonia, 4.3 

 per cent). 



No. 10—

Dried blood, 13 per cent nitrogen 555 pounds 



Muriate of potash, 50 per cent potash 80 pounds 



2,000 pounds 



This mixture is a concentrated one, on account of high-grade nitro- 

 genous and potassic materials being used, and will contain : available 

 phosphoric acid, 9.6 per cent; potash, 2.0 per cent; nitrogen, 3.6 per 

 cent (equal to ammonia, 4.4 per cent). 



No. 11—

Dried blood, 13 per cent nitrogen 600 pounds 



Muriate of potash, 50 per cent potash 90 pounds 



2,000 pounds 



This mixture is quite concentrated, on account of the high-grade 

 phosphatic and potassic materials used, and will contain : available 

 phosphoric acid, 10.5 per cent; potash, 2.3 per cent; nitrogen, 3.9 per 

 cent (equal to ammonia, 4.7 per cent).
