Increase in seed cotton per acre when kainit was added: 



, To unfertilized plot 70 lbs. 



To cottonseed meal plot 240 " 



To acid phosphate plot 420 " 



To cottonseed meal and acid phos. plot. . . .210 " 



Average increase with kainit 235 " 



Applied singly, every fertilizer entailed a finaacial lo.ss. 

 In combination, each of the three fertilizing material was 

 efifective, indicating that the soil was deficient in nitrogen, 

 phosphoric acid and potash. Kainit was most effective. 

 The most profitable fertilizer consisted of a mixture of kain- 

 it and acid phosphate. 



GROUP V. PHOSPHORIC ACID AND NITROGEN 

 ABOUT EQUALLY EFFECTIVE, AND POTASH 

 NOT VERY EFFECTIVE. 

 Experiment Made by T, T. Meadows, Cusseta, Chambers
