EFFECT OF NITROGENOUS FERTILIZERS. I4I 
protein in the corn, corresponding to the increase in the 
amount of nitrogen in the fertilizer. Thus in the experiments 
with nitrate of soda as the source of nitrogen the proportions 
of protein were as follows: in the corn from the mineral plots, 
10.13 per cent.; from the plots with 25 pounds of nitrogen, 
10.80 per cent.; from the plots with 50 pounds of nitrogen, 
11.50 per cent.; from the plots with 75 pounds of nitrogen, 
12.07 per cent. In the experiments in which sulphate of 
ammonia was the source of nitrogen there was likewise an in- 
crease in the protein with the increase in the nitrogen supplied, 
but the proportion of protein was not quite so large as in the 
mate ingredtents of corn (grain) and stover, with a comparison of the 
having nitrogen with the yield from the mineral plot.
