Soil Enzyme Activity
Soil enzymes are a class of biologically active substances with catalytic capacity that are secreted by microorganisms, living plants and animals and released in the soil by the decomposition of plant and animal residues and remains, and can be divided into four major categories according to the principle of action: hydrolytic enzymes, oxidoreductases, transferases and cleavage enzymes. Soil enzymes are one of the constituents of soil and participate in the natural material cycle including biochemical processes in soil. The enzymatic action of soil enzymes occurs on the surface of soil particles, plant roots and microbial cells with unity with the environment, and soil enzymes give the soil the ability to metabolize living tissues similar to that of living organisms.
Our Solution
Soil enzyme activity reflects the intensity and direction of various biochemical processes in the soil, and its activity is one of the important indicators for soil fertility evaluation and also an important indicator for soil self-purification capacity evaluation. Soil enzyme activity has a significant correlation with soil physical and chemical properties, fertility status, and agricultural practices. Therefore, it is important to study the influencing factors of soil enzyme activity and improve soil enzyme activity to improve soil ecological environment and soil fertility.

Applications
The factors influencing soil enzyme activity are very complex. Soil enzyme activity is significantly influenced by microbial species, hydrothermal condition, pH, structural composition, nutrient abundance, pollution level, and fertilization method. Since soil enzyme activity is one of the important indicators for evaluating soil fertility, research on the factors influencing soil biological activity will always be an important part of theoretical and applied research on soil fertilization.
