sod for Acid phosphate, 14 per cent, phosphoric acid 965 Ibs. 



Plants Cotton-seed meal, 6.59 per cent, nitrogen, 2-5 phosphoric 



acid and 1.5 potash 750 Ibs. 



Nitrate of Soda, 15 per cent, nitrogen no Ibs.

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.). 



p,. - This material is quick-acting because of its 



<> . 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 

 blood. Nitrate of Soda is frequently used as a top dressing 

 for corn and is a valuable material for use in this way. A 

 good application is 50 to 75 pounds per acre, distributed 

 along the side of the row or dropped beside the plants and 

 three or four inches from them, or else where there is a ridge 

 in the center it may be distributed on this and when it is 

 thrown out the Nitrate will be thrown to the two sides of 

 the row.
