METHOD OF DETERMINING CATALASE-CATALYZED HYDROGEN PEROXIDE DEGRADATION RATE IN SOILS

摘要

FIELD: soil science.;SUBSTANCE: estimation of biological activity and soil fertility from enzymatic activity of soils comprises measuring oxygen emission rate when soil is brought into interaction with hydrogen peroxide. The latter, prior to be used, is converted into powdered state by thickening with 38-42 wt % of silica powder.;EFFECT: enabled determination directly under real soil conditions.;1 tbl, 3 ex
