The number of experiments in each category in the table 
represents the number of separate field experiments in which 
samples were taken for analysis. Each field experiment in- 
cluded several plot experiments. The same experiments were 
repeated, in several instances, through quite a number of years. 
It will be noticed that the number of plot tests and the number 
of analyses do not agree in all cases. This is due to the fact 
that in some of the experiments duplicate samples were taken 
and were analyzed separately ; while in a few other experiments 
samples from plots having nitrogen in the same quantities, but 
in different materials, were combined and analyzed as one 
sample. In most of the experiments with cereals the seeds 
and the straw or stover were analyzed separately. In a few of 
them, however, only the seeds were analyzed. In the experi- 
ments with one of the leguminous crops (the soy beans) it was 
found impracticable to get the samples of the leaves and the
