Increase of seed cotton per acre when kainit was added: 



To unfertilized plot 118 lbs. 



To cottonseed meal plot — 53 " 



To acid phosphate plot — 159 " 



To cottonseed meal and acid phoe, plot — 141 " 



Average decrease wich kainit 59 " 



The chief need of this recently cleared land was for acid 

 phosphate. As usual, on fresh land cottonseed meal wa.s 

 not very effective. Kainit was not needed. The most profita- 

 ble fertilizer was the mixture of acid phosphate and cotton- 

 seed meal, which was only a few cents ahead of acid phos- 

 phate used alone. 



These results accord with those obtained in. a two years' 

 test conducted by Mr. J. W. Pitts, Creswell Station, Shelby 

 county, in showing a special need for phosphoric acid and 

 no increase from potash. 



Experiment Made by J. A. Logan, Clanton, Chilton County. 



Gray sandy soil ; pale red subsoil. 



The field used was cleared of the original growth of pine 

 and oak ten or fifteen years ago. Corn was the crop in 1895 

 and 1896. 



The report does not indicate whether the yields were se- 

 riously affected by rust, although this was present on some 

 plotis.
