SOILING INCREASES CAPACITY OF FARM 38 
A farmer having a one-hundred-acre farm 
could provide, under the soiling system, summer 
and winter roughage for fifty to seventy-five head 
of cattle. Under the pasturing system he would 
not have a sufficient area to provide more than 
summer pasture, as each animal would require 
about two acres; thus he would not be able to 
provide any forage for winter use. In other words, 
the soiling system virtually increases the efficiency 
of areas available for dairying from four to six 
times. 
Under good systems of pasturage, it would 
require at least 100 acres to supply the pasture 
necessary for fifty cows, whereas by the soiling 
system 100 acres would be capable of providing 
food for 300 cows for the same period. All of the 
large dairies producing sanitary milk for the best 
city trade, and keeping from 50 to 500 cows, prac- 
tice soiling and find it much more economical than 
pasturing; in fact, it would be practically impos- 
sible, in many instances, to conduct the business 
if pasture were the only source of summer succu- 
lent food. 
EXPERIMENTS TO DETERIMINE THE COST OF NUTRIZNTS 
In experiments at the New Jersey Station on 
the yield and cost of nutrients in soiling systems, 
it was shown that, while both yield and cost varied
