Acid phosphate, 14 per cent, phosphoric acid 1,045 't)^- 



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

 phoric acid and 1.5 potash . . . , 520 lbs. 



Nitrate of Soda, 15 per cent, nitrogen 225 lbs. 



Kainit, 12.5 per cent, potash 210 lbs.

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, 8.0 per 

 cent.; potash, 1.7 per cent.; nitrogen, 3.4 per cent, (equal to 

 ammonia, 4.0 per cent.).

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, 

 7.7 per cent.; potash, 1.7 per cent.; nitrogen, 3.3 per cent, 

 (equal to ammonia, 4.0 per cent.). 



This material is quick-acting because of its 

 Nitrate of Soda, easy solubility in water. For this reason 



when used in a considerable quantity in 

 fertilizers at time of planting on light sandy land, there is 

 danger of its being leached beyond the reach of the roots of 

 the plants before they can use it. On clay lands and loams 

 having good subsoils, to them this danger does not exist, 

 certainly not to the extent that it does on light soils. A small 

 amount of nitrate of soda in the mixture will give the crop 

 a quick start and make its cultivation easier and more 

 economical. On light lands it would likely be better to omit 

 the nitrate from the mixture and apply it as a top dressing 

 between the tenth and last of June on early corn. Nitrate of 

 soda may take the place of a portion of the other nitrogen- 

 furnishing materials in any of the formulas, one pound of 

 nitrate being equal in its content of nitrogen to 2.2 pounds 

 cotton-seed meal, 2 pounds fish scrap, 1.2 pounds dried
