between the nitrogen in the crop and that used as fertihzer. On 

 the whole there seems to be no tendency for nitrogenous fer- 

 tihzer to improve the feeding value of the so}^ bean seeds.

SUMMARY AND DEDUCTIONS. 



The purpose of the pot experiments was to study the effects of 

 nitrogenous fertilizers on the percentages of nitrogen and protein 

 in some of our commo7i farm crops. In this respect they are simi- 

 lar to the field experiments with nitrogenous fertilizers which the 

 Station has conducted durijig the past tivelve years; but it ivas 

 thought that with the crops grown in pots the conditions of the 

 experiments would be more fully ii?ider co7itrol and the results 

 would thus have an increased value, and would serve to verify 

 the results obtained in the field experirnejits.
