MAINTAINING THE ORGANIC MATTER OF SOILS 163

7. Loss of Manure and its Prevention. A source of great 

 loss occurs in the handling of manure after it is produced. In too 

 many cases it is left in the lot or under the eaves of the barn 

 or shed until the organic matter is decomposed and a large amount 

 of the fertility is carried away. In the process of rotting there is a 

 large amount of organic matter lost. To determine the amount 

 of loss the Ontario Station placed four tons of mixed cow and 

 horse manure in equal amounts in a protected shed and a like 

 amount in an open bin exposed to the weather. The four tons 

 contained 1!)38 pounds of organic matter. The losses are given 

 in the next table.
