THE USE OF STABLE MANURE

 is one reason for farming. 



Manure on Potatoes. There are excellent 

 cash crops that may get more than their fair share 

 of the farm supply of fertility, and against the 

 interest of fields in the farm not adapted to cash 

 crops. The justification is found in the farm 

 ledger. In some regions potatoes are the best 

 crop in point of net income per acre, where the 

 acreage is kept restricted so that there may be 

 plenty of organic matter to help in conserving 

 moisture. It is not good practice to use fresh 

 manure, and especially that from horse-stables, 

 for potatoes. A heavy application makes an 

 excessive growth of vine, and the yield of tubers 

 suffers. A stronger deterrent is the effect that 

 fresh manure has on the development of the spores 

 that produce the disease known as potato-scab. 

 Rotted manure is less dangerous, and few crops 

 repay its use in higher degree than the potato. 

 Some growers prefer to make heavy application 

 of fresh manure to grass for corn, and follow with 

 potatoes so that they can profit by the rotted 

 organic matter that remains. In this way the 

 physical condition is made excellent, moisture is 

 well held in a dry season, and commercial fertilizers
