Biochemical properties of acid soils under native grassland in a temperate humid zone

Abstract The biochemical properties of 29 soils under native grassland in a temperate humid zone (Galicia, north‐west Spain) and subject to low intensity management (at least during the last 100 years) were determined with the aim of establishing a reference database to allow future comparative studies of the effect of grassland management on soil quality. Several biochemical properties were quantitatively and qualitatively studied. These properties were: labile carbon, microbial biomass carbon, microbial respiration, metabolic quotient, net nitrogen mineralisation and the potential activities of dehydrogenase, catalase, phosphodiesterase, phosphomonoesterase, case in‐protease, BAA‐protease, urease, cellulase, β‐glucosidase, invertase and arylsulphatase. The values of these properties were generally within the ranges of those reported for grassland soils from other parts of the world, but some properties differed both quantitatively and qualitatively from those of forest climax soils in the same area.
