Interpretive Summary: Phosphorus (P) exists in animal manure in various forms. In this study, we investigated the distribution of P forms in 13 dairy manures obtained from different sources and their relationships with total manure P. Although the amounts of various P forms were different in these manures, relationships of some P forms with total manure P were observed. For instance, water-extractable inorganic P, the major inorganic P component, and phytate-like P, the major enzymatic hydrolysable organic P, were both positively correlated to total manure P. Findings in this study could enhance our understanding of manure P chemistry, providing insight into improving management of manure P.
