No. 2— 



Acid phosphate, 14 per cent phosphoric acid 1,015 pounds 



Cotton-seed meal, 0.59 per cent nitrogen, 2.5 per cent phos- 

 phoric acid and 1.5 per cent potash 415 pounds 



Nitrate of soda, 15 per cent nitrogen 180 pounds 



Kainit, 12.5 per cent potash 390 pounds 



2,000 pounds 



In this formula one-half of the nitrogen is supplied by nitrate of 

 soda, and the other one-half by cotton-seed meal. This mixture will 

 contain: available phosphoric acid, 7.6 per cent; potash, 2.7 per cent; 

 nitrogen, 2.7 per cent (equal to ammonia, 3.3 per cent). 



No. 3— 



Acid phosphate, 14 per cent phosphoric acid 955 pounds 



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

 phoric acid and 1.5 per cent potash 605 pounds 



Nitrate of soda. 15 per cent nitrogen 90 pounds 



Kainit, 12.5 per cent potash 350 pounds 



2,000 pounds 



In this formula one-fourth of the nitrogen is supplied by nitrate of 

 soda and the other three-fourths by cotton-seed meal. This mixture 

 will contain : available phosphoric acid, 7.4 per cent ; potash, 2.6 per 

 cent; nitrogen, 2.6 per cent (equal to ammonia, 3.1 per cent). 



No. 4— 



Acid phosphate, 16 per cent phosphoric acid 830 pounds 



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

 phoric acid and 1.5 per cent potash 830 pounds 



Kainit, 12.5 per cent potash 340 pounds 



2,000 pounds 



This mixture will contain: available phosphoric acid, 7.7 per cent; 

 potash, 2.7 per cent; nitrogen, 2.7 per cent (equal to ammonia, 3.3 

 per cent). 



No. 5— 



Acid phosphate, 14 per cent phosphoric acid 850 pounds 



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



* phoric acid 690 pounds 



Kainit, 12.5 per cent potash 460 pounds 



2,000 pounds 



This mixture will contain : available phosphoric acid, 8.0 per cent ; 

 potash, 2.9 per cent; nitrogen, 2.9 per cent (equal to ammonia, 3.5 

 per cent). 



No. 6— 



Acid phosphate, 16 per cent phosphoric acid 790 pounds 



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

 phoric acid 730 pounds 



Kainit, 12.5 per cent potash 480 pounds 



2,000 pounds 



This mixture is more concentrated than the foregoing ones, on account 

 of the higher-grade materials used, and will contain : available phos- 

 phoric acid, 8.5 per cent; potash, 3.0 per cent; nitrogen, 3.0 per cent 

 (equal to ammonia, 3.6 per cent).
