FIELD EXPERIMENTS WITH FERTILIZERS. 169 
quoted from the Annual Report for 1891: ‘‘The results show 
that phosphoric acid had the most marked effect, nitrogen con- 
siderable, while potash gave but little increase over nothing. 
There is no very great increase from the use of any of the ingre- 
dients, and it seems probable that the soil was supplied with 
accumulated stores of fertility which the two years’ cropping had 
not entirely exhausted.”

The results for the past season show that all of the fertilizing 
ingredients were needed to produce good crops, but that potash 
was most essential, while in 1892, with oats, the nitrogen had the 
most marked influence. This illustrates the importance of mod- 
ifying the fertilizer in accordance with the demand of the crop as 
well as the peculiarities of the soil.
