Soil enzyme is a sensitive indicator of soil fertility condition.The dynamic and thermodynamic characteristics of soil enzymes can illustrate the enzyme catalyzed soil biochemical processes and explain the changing mechanisms of soil fertility.In this paper,the dynamic and thermodynamic parameters of soil reactions catalyzed by soil enzymes were analyzed for the soils under 25 years continuous fertilization.The objective of this research was to reveal the effects of long-term fertilization on soil fertilit...
