191. Value of Protected Manure. Manure that 

 is produced under cover has greater crop-producing 

 power than when cared for in any other way. Ex- 

 periments by Kinnard show that such manure pro- 

 duced 4 tons more potatoes per acre than pile manure, 

 while 1 1 bushels more wheat per acre were obtained 

 from land which had the previous year received the 

 covered manure than from land which received the 

 uncovered manure. 62 



THE USE OF MANURE 



192. Direct Hauling to Fields. It is always desir- 

 able, whenever conditions allow, to draw the manure 

 directly to the field and spread it, rather than to allow 

 it to accumulate about barns or in the barnyard. 

 When taken directly to the field from the stable no 

 losses by leaching occur, and the slight loss from fer- 

 mentation and volatilization of the ammonia are more 

 than offset by the benefits derived from the action of 

 the fresh manure upon the soil. When manure un- 

 dergoes fermentation in the soil, as previously stated, 

 it combines with the mineral matter of the soil and 

 produces humates. The practice of hauling the ma- 

 nure directly to the field and spreading it with a ma- 

 nure spreader is the most economical way of caring 

 for it.
