STABLE MANURE

 an investment of $ 30 in the total liquid and solid

 values usually given are relative and suggestive. 

 They are aids in forming judgment. Actual

The Content of Manure. When the crops of 

 a farm are fed, the manure contains nearly all the 

 plant-food that went originally into the crops. In 

 the case of idle work-horses on a maintenance 

 ration, the manure contains practically all the 

 plant-food. Cows giving milk remove some fer- 

 tility, and a growing calf or colt may take out 

 30 per cent. There is some waste beyond control, 

 but when manure is made on tight floors with good 

 bedding, and is drawn to the field fast as made, 

 on the average it carries back to the soil fully 

 four fifths of the plant-food that existed in the 

 feed. Disregarding all cash valuations for the 

 moment, here is an index of value that should be 

 sufficient in itself to encourage the feeding of crops 

 on the farm and the careful saving of the manure.
