Soil Biological Testing
Soil CO2 Biological Test is a relatively new test that has been made readily available for use in cropping analysis.
The biological test is conducted on a sample of soil in a controlled environment where the Carbon Dioxide (CO2)produced by the micro-organisms in the soil is measured over a given time period.
From the amount of CO2 generated over the time period gives an indication of the level of microbial activity present in the soil, the greater CO2 levels the greater microbial activity on your soil.
