dehydrogenase's activity was approximately 2-fold greater, acid phosphatase,
urease and protease approximately 1.5-fold greater than in
soil without fertilization, which was related to both the amount of carbon
substrates available for microorganisms, enzymes, and favorable
changes in soil pH. Especially wide range of dehydrogenases’ enzyme
activity indicates the usefulness of this group of enzymes to assess soil
environment changes under the influence of tillage system.
