176 PROFITABLE DAIRYING 



is easily possible, and there are those who look 

 forward to the time when there will be a cow to 

 the acre on the best dairy farms. Should each 

 cow produce 5,000 pounds of milk annually, we 

 would have 50,000 pounds of milk. This amount 

 will make on the average 5,000 pounds of cheese, 

 or 2,000 pounds of butter. It has already been 

 shown that this amount of milk, if sold from 

 the farm to city consumers, removes about $45 

 worth of fertility, while the 5,000 pounds of 

 cheese contains about $25 "worth, and the ton 

 of butter less than 50 cents' worth. If clover 

 or any of the other legumes has been raised for 

 feed it has probably turned this value in air 

 nitrogen back into the soil, so that very little if 

 any of the fertility has been lost. 



The demands of other types of farming on the 

 soil. Now, what would be the result of raising 

 grain, tobacco, potatoes or beets for the market 

 on the same plat of ground? Let us see. The 

 average production of oats, corn, wheat, rye, 

 barley, and potatoes for the United States,, 

 according to the year book of the Department of 

 Agriculture, is as follows: 



Oats 30 bu. per acre 



Wheat 14 bu. per acre 



Rye 15 bu. per acre 



Corn 25 bu. per acre 



Barley 25 bu. per acre 



Potatoes ' 90 bu. per acre
