farm where no leguminous crop had grown for a number 

 of years. The absence of any considerable rain between 

 April and August ruined the yield. 



The stand was uniform on all plots. The chief need of 

 this sand bank this excessively dry year was for kainit, but 

 the largest yield was from complete fertilizer. 



Experiment Conducted by W. T. Chism^ in 1901, 1902 and 

 1903, AT ViCK^ Bibb County. 



Grayish, mndy, second bottom with yellow suhsoil. 



This land has been long in cultivation. On adjacent, 

 similar land the forest growth consists of shortleaf pine, 

 white and red oaks, gum, cucumber tree, dogwood, hickory 

 and beech. For yields and increase see table on page 49. 



In 1901. All plots were reduced to the same number of 

 plants, 6,400 per acre. The two preceding crops had been 

 cotton. The largest increase, 388 pounds of seed cotton 

 per acre, or a net profit of |5.31 per acre, was obtained 

 where a complete fertilizer was used. This year nitrogen 

 was apparently the plant food chiefly needed, but both phos- 

 phoric acid and potash Avere advantageous. There was 

 practically no rust on an}' plot. 



In 1902. Dry weather, almost continuous from April till 

 August, made the yields on all plots low and all fertilizers 

 practicallj' useless. 



In 190S. The two preceding crops had been cotton. The 

 spring was late and cold. No rust occurred. As in 1901 

 cotton seed meal greatly increased the yield while phosphate 

 and kainit were less important, but advantageous. Plot 10 

 afforded the largest increase, 446 pounds, or a net profit of 

 $6.19 per acre. 



The results suggest that the phosphate in the complete 

 fertilizer might have been much reduced without injury to 

 the crop.
