Soil Microbial Biomass and Physicochemical Indexes Analysis

Soil is an important part of the environment, and there is a close relationship between vegetation quality, ecosystem sustainability and soil quality. The microbial, physical and chemical properties of the soil are all indicators that indicate the health of the soil. The detection of soil quality is to detect and analyze the microbial biomass, organic matter, minerals, fertility, heavy metal elements, pesticide residues and other indicators in the soil.

Reliable detection of soil quality is of great significance for formulating good measures to improve soil quality. Creative BioMart Microbe provides customers with comprehensive testing items for soil quality, covering microbial biomass analysis, enzyme activity analysis, physical property analysis, and chemical property analysis.
