The silo is primarily a means for conserving food material. With the preservation through fermentation of the mass of corn or other crops in the silo there is generally the loss of a small amount of food material. Certain losses are apparently necessarj'^ in the proper fer- mentation ; others are probabW unnecessary. For several years the Dairy Division has been studying to find out more definitely what losses incident to the ensiling of corn are neces- sary and what is the proper method of handling the crop to prevent such losses. This bulletin deals with the losses of nitrogen and other elements in corn silage made under ordinary farm conditions. PREVIOUS INVESTIGATIONS. The earliest recorded studies of the loss of nitrogen and other elements during the ensiling of corn were made with material very low in dry matter and stored in pit or tub silos.
