The analysis of the oats from the several plats differently 
fertilized shows that there was little influence of the fertilizer 
upon the composition of the ash, for when calculated in the dry 
substance the differences in composition are very small. 
The amount of chemical work on hand at the time prevented our 
making analyses of the straw, ‘but if we assume that the compo- 
sition of the straw was the same as that for other samples analyzed 
from the same field in previous years, then we can calculate 
the amounts of the several fertilizing ingredients removed per 
acre by such a crop of oats. As the variation from former 
analyses for straw can not be great, we use these figures for 
estimating the average amount removed. 
The following table gives the yield calculated per acre :
