Amount of Mineral Ingredients removed from the Soil by an Acre 
of Graipe Hops. 
In the present instance I believe about 1260 to be the number 
of hills contained in an acre. 
Therefore, by multiplying the numbers in the preceding table 
by 420, 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, 1 give in the following 
table these weights in pounds and ounces avoirdupois : —
