 "Soiling" is the feeding of animals on green herb- 

 age that is cut and carried to them (as distin-

THE MEASURES OF VALUE IN FORAGE CROPS 



The value of any forage crop is determined by 

 a number of conditions, the first, and in the long 

 run probably the most important, being the actual 

 food, or the amount of dry matter, that may be 

 secured from a given area and its usefulness as 

 measured by the kind and proportion of the 

 nutrients contained in it. A second considera- 

 tion is its adaptability and usefulness foi- the 

 various purposes, as, for example, for a soiling
