RELATIONSHIP BETWEEN SOIL ENZYMES AND PHYSICOCHEMICAL PROPERTIES OF PRELUVOSOIL

Soil is a heterogeneous medium of solid, liquid, and gaseous phases varying in its properties both across the landscape and in depth (Lou and Zhou, 2006). Microbiological properties can serve as soil quality indicators because after plants soil microbes are the second most important biological agent of the agricultural ecosystem. Enzyme activity is an important indicator of soil microbiological properties. The role of soil enzymes, in terms of the ecosystem, is increasingly important and is defined by the relationships between soil enzymes and the environmental factors affecting their activities. Perhaps the most valuable single use of soil enzymes is to assess the effects of various inputs on the relative health of the soil. Numerous studies have been conducted to determine changes in a soilenzyme activities caused by pesticides, fertilizers, and other agricultural chemicals.
