were located near Dothan, Henry county; Union Springs, 

 Bullock county; Coatopa, Sumter county; and Naftel, Mont- 

 gomery county. 



The experiments in which nitrogen was most efife^^tive 

 were located near Jackson, Clarke county; Perote, Bullock 

 county; Greensboro, Hale county; and LeGrand, Montgom- 

 ery county. 



The experiments in which phosphoric acid, potash and 

 nitrogen w^ere all greatly advantageous were situated near 

 Benneyis, Talladega county; Thomaston, Marengo county; 

 Rutledge, Crenshaw county; and Daphne, Baldwin county. 



The experiments in which nitrogen and phosphoric acid 

 were about equally beneficial, and potash of slight or no ef- 

 fect, were located near Cusseta, Chambers count^', and 

 » Kaylor, Randolph county. 



Fertilizer experiments with cotton were made in eight 

 other localities, in which the results were not entirely cou- 

 clasive. 



The fertilizer that afforded the maximum net profit in 

 the greatest number of localities was a complete fertilizer 

 made up as follows: 



200 pounds per acre cotton seed meal, 



240 pounds per acre high grade acid phosphate, and 



100 pounds per acre kainit. 



This fertilizer mixture contained 2.59 per cent, of nitro- 

 gen, 7.7.5 per cent, of available phosphoric acid, and 2.93 

 per cent, of potash. 



The season was generally dry, and rust or other leaf dis- 

 ease was widelj^ prevalent and very destructive. Under 

 these conditions, kainit greatly reduced the injury from 

 leaf diseases in Gl per cent, of the experiments, or eight 

 out of thirteen experiments of which complete reports were 

 made. This does not imply iso favorable an effect of kainit 

 in seasons when weather conditions are normal, and when 

 rust or blight is less widely prevalent.
