TALLAPOOSA COUNTY, 4 MILES SOUTH OF 



DADEVILLE. 



J. D. Williams. 



Red loam, red clay subsoil. 



This land has been in cultivation for about 20 years. The 

 preceding crop was oats. Considerable damage was done by 

 rust on Plots 9 and 10, and slight damage was done by wilt. 

 There was a nearly perfect stand. 



All of the complete fertilizers were profitable, as were all 

 other plots where cotton seed meal was added. Cotton seed 

 meal, when applied alone, gave a profit of $3.18 or 76 per cent 

 on the investment. The average estimated increase of seed 

 cotton per acre was 280 pounds for cotton seed meal ; 91 pounds 

 for acid phosphate; and 112 pounds for kainit. The plots in 

 this experiment were only yV -acre, instead of % acre as di- 

 rected, making the rate of fertilization heavier; and hence the 

 results cannot be compared with those of other experiments 

 reported. 



Increase of seed co'ton per acre when cotton seed meal was added: 



To unfertilized plot 240 lbs. 



To acid phospha e plot 222 lbs. 



To kainit plot 258 lbs. 



To acid phosphate and kainit plot 399 lbs. 



Average increase with cotton seed meal 280 lbs. 



Increase of seed co ton per acre when acid phosphate was added: 



To unfertilized plot 60 lbs. 



To cotton seed meal plot 42 lbs. 



To kainit plot 60 lbs. 



To cotton seed meal and kainit plot 201 lbs. 



Average increase with acid phosphate 91 lbs. 



Increase of seed cotton per acre when kainit was added: 



To unfertilized plot 63 lbs.. 



To cotton seed meal plot 81 lbs. 



To acid phosphate plot 63 lbs. 



To cotton seed meal and acid phosphate plot 240 lbs-
