viii, 459 p. : ill. ; 26 cm. Environmental Chemistry of Animal Manure edited by Zhongqi He examines the chemical composition, transformations, and environmental impacts of animal manure in agricultural systems. Animal manure—composed mainly of feces, urine, bedding materials, and feed residues—is a significant source of organic matter and essential plant nutrients such as nitrogen and phosphorus. However, with the intensification of livestock production, large quantities of manure have raised environmental concerns. The book synthesizes fundamental and advanced research on manure chemistry, focusing on organic matter characterization, nutrient dynamics (especially nitrogen and phosphorus), and the behavior of trace elements and heavy metals. It highlights how chemical processes in manure influence nutrient availability, mobility, and loss pathways, including volatilization, leaching, and runoff.
