This document discusses farm yard manure (FYM), including its definition, chemical composition, and methods of collection and storage. It provides the average percentages of nitrogen (N), phosphorus (P), and potassium (K) in the fresh excreta of common farm animals. It also lists factors that influence the composition of FYM and potential losses during handling and storage of FYM, such as loss of liquid/urine, loss of solids/dung, leaching, and volatilization.
