This document specifies a method for the measurement of several hydrolase activities (arylamidase,arylsulfatase, β-galactosidase, α-glucosidase, β-glucosidase, N-acetyl-glucosaminidase, acid, alkalineand global phosphatases, urease) simultaneously (or not) in soil samples, using colorimetric substrates.Enzyme activities of soil vary seasonally and depend on soil chemical, physical and biologicalcharacteristics. This method can be applied either to detect harmful effects on soil enzyme activitiesderived from toxic substances or other anthropogenic agents in contaminated soils against a controlsoil, or to test chemicals.
