Phosphatases play a key role in the mineralization of organic phosphorus in soils; however, the relative contributions of bacteria and fungi to phosphatase activities remain unclear. Sources of activities of two phosphomonoesterases (acid phosphatase and alkaline phosphatase) and phosphodiesterase in two arable Andisols and two forested Inceptisols were evaluated using selective inhibition with antibiotics. The results showed that all three phosphatases were primarily produced by bacteria in the
