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, ^.^ per cent.). 



Acid phosphate, 14 per cent, phosphoric acid 955 lbs. 



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

 phoric acid and 1.5 potash 605 lbs. 



Nitrate of soda, 15 per cent, nitrogen 90 lbs. 



Kainit, 12.5 per cent, potash 350 lbs. 



2,000 lbs. 



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.). 



The remarks under corn regarding ^^^^^^ g^^^ ^^^ 

 these two materials apply also to cotton, as j^ji-j-^tg of Soda 

 do the suggestions concerning the change 

 in the quantity of nitrogen-supplying materials in the for- 

 mulas, should cotton follow peas or any other leguminous 

 crop. In Formula No. 3 one-fourth of the Nitrogen is sup- 

 plied by Nitrate of Soda, with the view of giving the crop 

 a quick start, and in No. 2 one-half of the Nitrogen comes 

 from this source. On light lands it will be good practice to 

 omit this Nitrate from the mixture and apply it as a side- 

 dressing about the middle of June. Good results come from 

 the use of it in this way on heavy types of land. Where land 

 does not produce a good stalk of cotton, and fertilizers are 

 used which contain only a moderate amount ot nitrogen, or 

 ammonia, good results are obtained from a side-dressing of 

 50 to 100 pounds of nitrate of soda per acre. The nitrate 

 should be distributed along one side of the row, or where 

 there is a ridge in the middle it may be put on this and when 



the ridee is thrown out the nitrate will be . i:^^+:^„ „*
