6. — Amount of Mineral Ingredients removed from the Soil by an 
Acre of Hops. 
The number of hills of hops to an acre varies in different loca- 
lities. In some places 1000, in others 1260, in others 1440 hills 
go to the acre. 
In the present instance I believe about 1000 to be the number 
of hills contained in an acre. 
Therefore, by multiplying the numbers in the preceding table 
by 250, we shall have the actual weights of the various inorganic 
ingredients of the soil removed from an acre of land by the hop. 
For the convenience of agriculturists, I give in the following 
table these weights in pounds and ounces avoirdupois.
