SOILS AND FERTILIZERS 477 



Muriate or sulphate of potash 100 pounds. 



Filler 150 pounds. 



Total 2000 pounds. 



This fertilizer has the same composition as No. Ill, but contains 

 about one-fourth of its nitrogen in the immediately available form 

 of nitrate of soda. This would be ready to give the plant a rapid start. 



Formula V. 8-3.64 Fertilizer. 



Acid phosphate, 14 per cent 1100 pounds. 



Cottonseed meal 430 pounds. 



Nitrate of soda 200 pounds. 



Muriate or sulphate of potash 160 pounds. 



Total 2000 pounds. 



This fertilizer is used for truck crops, potatoes and other crops 

 requiring more nitrogen than corn or cotton requires. One-half of 

 the nitrogen is in the active form of nitrate of soda. If desired, the 

 200 pounds of nitrate of soda could be replaced by 430 pounds of cot- 

 tonseed meal; this alters the composition of the fertilizer and the 

 nitrogen is not so immediately available, but it is less likely to be 

 washed out. 



Formula VI. 8-4 Fertilizer. 



Acid phosphate, 14 per cent 1100 pounds. 



Cottonseed meal 900 pounds. 



Total 2000 pounds. 



This fertilizer does not contain any potash except a small quan- 

 tity in the cottonseed meal. It is used for potatoes in some parts 

 of the State. 



Formula VII. 10-2 Fertilizer. 



Acid phosphate, 14 per cent 1500 pounds. 



Kainit 350 pounds. 



Filler 150 pounds. 



Total 2000 pounds. 



This fertilizer contains 10 per cent phosphoric acid and 2 per 

 cent potash, and it is used when no nitrogen is desired. 

 Formula VIII. 104 Fertilizer. 



Acid phosphate, 14 per cent 1500 pounds. 



Muriate or sulphate of potash 170 pounds. 



Filler 330 pounds. 



Total 2000 pounds. 



This fertilizer contains 10 per cent of phosphoric acid and 4 

 per cent of potash. 



In the above formulas acid phosphate containing 14 per cent 

 available phosphoric acid is used. If acid phosphate containing 12 

 per cent phosphoric acid is used, the percentage of phosphoric acid 

 will be correspondingly reduced. If 16 per cent acid phosphate is 

 used, the percentage of phosphoric acid will be increased.
