applied. One thing seems evident, i. e., that, in experimenting with 
this soil, the check plots ought to alternate with the experimental 
plots. While this arrangement of plots would have been a little 
more satisfactory it would not have removed all the difficulties. 
Plots 17 and 31 lie end to end and each received 10 tons of stockyard 
manure in 1909. Plot 17 received in addition to this in 1909, P. 55, 
K. 65, N. too and burnt lime 2 tons, and yielded 21.9 tons of beets; 
in 1910 the same fertilizers were added with the exception of the 
burnt lime and yielded 15.9 tons of beets. Plot 31 received nothing 
in addition to the 10 tons of stockyard manure in 1909, and yielded 
11.3 tons of beets; in 1910, P. 250, K. 200 and N. 100 were applied 
and the yield was 13.2 tons of beets. With such results I do not 
think it possible to distinguish how much is due to differences in the 
soil and how much to other causes. An inspection of all of the 
results will simply justify a general statement that the application 
of fertilizers increased the crops, but that this increase is neither 
great nor regular enough to commend the practice from the stand¬ 
point of profit. 
It may be worth the while to indicate the composition of the 
fertilizers used. The Chile saltpetre, sodic nitrate, 90.62 percent 
nitrate, potassic sulfate 89.87 percent, equivalent to 48.50 percent
