WebSoil acid phosphatase activities were closely linked to forest successional stages, with enhanced values in the later stages of forest succession. In the dry season, soil acid phosphatase activities in the three forests showed a rising trend with increasing precipitation treatments. WebJul 6, 2024 · Soil enzymes are mainly oxidoreductases (e.g. dehydrogenase) and hydrolases (e.g. β-glucosidase, urease, phosphatase, and sulphatase). Dehydrogenase is usually used as a indicator of soil microbial activity (Tan et al., 2014; Trasar-Cepeda et al., 1999) and short-term alterations in soil (Nannipieri et al., 2002, 2024 ).
