FIELD EXPERIMENTS WITH FERTILIZERS. I99 
In addition to the plots in the regular soil test, which include 
the plots from 0 to 000 inclusive in the above diagram, and are 
treated with the commercial fertilizers as explained, two other 
plots, X and Y, of the same size are included in the series, the 
former being treated with stable manure and phosphoric acid, 
and the latter with a larger quantity of stable manure, but 
without the addition of the mineral fertilizer. 
Experiment of 1897.—From the rotation of crops given above 
it will be seen that soy beans were planted in 1897 following 
oats in 1896, instead of cow peas which had previously suc- 
ceeded oats in the order of rotation. The results of the ex- 
periments with this crop are given in Table 47 below. ‘The 
season was so wet, as before explained, that the field experi- 
ments were spoiled. ‘The experiments for 1897, therefore, are 
not discussed. .

Lixperiments of r898.—'The soil test of 1898 was made with 
corn and seemed to be normal throughout, although the grow- 
ing season of this year, while not so wet as that of 1897, was 
somewhat wetter than the average, owing to heavy rains in 
July and August. Quite a marked difference in the growth on
