Cottonseed meal was most effective. It was also most 

 profitable, although at best the profit wais slight. There 

 was a large financial loss when a complete fertilizer was 

 used at the rate of 540 and 640 pounds per acre.

This land has been in cultivation, chiefly in cotton, for 

 more than thirty yeans. The original growth is reported as 

 hickory, oak and other hard woods. The number of stalks 

 per eighth acre plot was as fellows: 1274 on plot 1, 1000 

 on plot 2, 1016 on plot 3, 1048 on plot 4, 1049 on plot 5, 1126 

 on plot 6, 1023 on plot 7, 838 on plot 8, 1027 on plot 9, and 

 1086 on plot 10. In the following table no corrections have 

 been made for a defective stand, for, judging by the fact 

 that the unfertilized plot with 838 plants yielded more 

 than the unfertilized plot with 1016 plants, the plots plant- 

 ed thickly had no advantage over other plots. The land 

 was level and apparently very uniform. There was some 

 rust on all plots, against which kainit was apparently in- 

 effectual.
