 tion r^nni. 



Lest any should misapprehend the lessons of this ex- 

 periment it is necessary to state that at no time in the 

 three-year period was any nitrogenous fertilizer applied 

 to any ciop on any of these plots, but that each crop was 

 supplicM^l with i)h()sphate and potash. 



The yearly application of cotton seed meal would have 

 lessened the differences between the plots, as it has done 

 in onr nnx)nblished rotation experiments, and would 

 have made the advantage in favor of legumes less 

 striking than in the exhibit above. 



Immediate Fertilizing Effects on Cotton of Velvet 



Bean Vines. 



On poor soil at Auburn an effort was made in 1898 

 and 1899 to ascertain the manurial value of the vines 

 and stubble of velvet beans. 



In 1898 cotton was grown on certain plots and velvet 

 beans on others. The fertilization of all plots in 1898 

 was not identical, but for a given fertilizer applied to 

 cotton there was a plot of velvet beans receiving the 

 same fertilizer. The velvet beans grew in drills 3^ feet 

 apart; the vines formed a dense mat of vegetation, but 

 did not mature seed. In March, 1899, velvet beans and 

 cotton stalks Avere plowed in and soon afterwards all 

 plots were fertilized alike with a mixture of 210 pounds 

 of acid phosphate and 10 pounds of muriate of potash 

 per acre. 



Russell cotton was planted in 3i feet drills on all 

 plots on April 21. From midsummer forward there was 

 a remarkable difference in the appearance of the two
