Increase in seed cotton per acre when kainit was added: 



To unfertilized plot 114 lbs. 



To cottonseed meal plot 17 " 



To acid phosphate plot —210 " 



To cottonseed meal and acid phos. plot. . . — 75 '" 



Average decrease with kainit 39 *' 



Acid phosphate and cottonseed meal were about equally 

 effective, both giving moderately profitable returns. Kainit 

 was used at a loss. The plot which yielded most profit was 

 the one to which acid phosphate alone was applied. 



Neither in 1896 nor in 1897 was the complete fertilizer the 

 moist profitable fertilizer for land capable of producing 800 

 to 1000 pounds of seed cotton per acre. 



INCONCLUSIVE EXPERIMENTS. 



The experiment near McLendon, Russell county, was 

 made by J. J. Blackstock on the farm of Hirsch Brothers. 



The field was level and the soil loamy. It had been 

 ■cleared about sixty years before. The original growth was 

 gum and short leaf pine. The stand was reported good. 



The variable effect of fertilizer in the several mixtures 

 renders conclusions impossible, but raises the suspicion 

 that the soil, by reason either of a sufficiency of all three of 

 the usual forms of commercial plant food, or because of de- 

 fective physical condition, was unable to profit by any of 

 the ordinary commercial fertilizers. In 1896 also the results 

 were negative or inconclusive. 



An experiment was made by J. B. Craddock on farm of 

 Southeast Alabama Agricultural School, Abbeville, Ala. : 



The land had been in cultivation for about fifty yeans. 

 The original growth was oak and hickory. 



The experiment is incomplete, having no unfertilized plot, 

 but by comparing the yield obtained by use of the mixture 

 containing all three fertilizers with tke yields afforded by
