 Biomass Soil Testing

The health of your soil determines the productivity of your garden or farm. Compost Queens offers microBIOMETER® soil testing to measure the microbial biomass (fungi and bacteria) in your soil.

Soil testing has traditionally measured the soil's  mineral and nutrient content. Compost Queens measures how biologically alive your soil is using microBIOMETER®.  Knowing the biological activity over time gives you a better understanding of how well those minerals and nutrients can actually be absorbed by your plants.

Research shows that biomass is the leading indicator of soil health as the soil microbes are what make minerals and other nutrients accessible to plants.


They also improve plant immunity and soil structure and increase the ability of the soil to hold water.  


Knowing how alive your soil is allows you to build and maintain a more regenerative ecosystem in your garden, farm, and community.
