or, as suggested by the Georgia Experiment Station, 

 perhaps a fertilizer containing 



Nitrogen 3% 



Phosphoric acid (soluble) 9% 



Potash 3% 



applied at the rate of 700 pounds to the acre, would be 

 approximately the best amounts to use under ordinary 

 circumstances. 



Method of application. 



The fertilizer should be applied in the drill at the 

 time of planting, and at the depth of not more than 

 three inches, and well mixed with the soil. In most cases 

 it is best to apply all of the fertilizer in one application 

 rather than in fractional applications, though with lands 

 in superior condition profitable applications may be made 

 again at the second plowing. Owing to the nearness of 

 the cotton belt to the supplies of superphosphate, and to 

 the cheap supplies of cotton-seed meal, the only fertilizer 

 necessary to import is potash. Hence it has become a 

 practice in most sections for the planter to make his own 

 formulas, using his own supplies of phosphoric acid and 

 nitrogen ; and home mixtures, made up of acid phosphate, 

 cotton-seed meal and muriate of potash, or kainit, are 

 largely used to supply the demands. The following for- 

 mula is an example of a good mixture : 



Acid phosphate 1200 Ib. 



Cotton-seed meal 600 Ib. 



Kainit .... 200 Ib.
