EFFECT OF NITROGENOUS FERTILIZERS. 145 
Effect upon the Composition of Oats. — The two special nitro- 
gen experiments with oats comprised 26 plots upon which 
nitrogen was applied in nitrate of soda, sulphate of ammonia, 
and dried blood. As in the experiments with corn, samples of 
both the grain and the straw without the grain were gathered 
when the crop was harvested, and were carefully prepared for 
analysis. With the data from these analyses, given in Tables 15 
and 16, are included also some of the results of analyses of grain 
from the soil test experiment. The figures given in these 
tables are the averages in bold face type in Tables 31 and 32 on 
pages 182 and 185.
