Get soil health results in the palm of your hand with our microBIOMETER. This incredible device uses a smartphone camera and our exclusive app to accurately measure the biomass of microbes up to 100 μm in size to determine the total microbe populations and the bacteria-to-fungi ratio, a leading indicator of the health of the soil food web.

The microBIOMETER can be used with soil, compost and compost teas, and microbial inoculants. Our app is available for both iPhone and Android devices, and soil test data is stored in the cloud, allowing it to be accessed from anywhere.

Our microBIOMETER allows growers to capture and analyze the scientific data they need to monitor and evaluate soil health. By correlating microbial biomass with soil fertility levels, farmers and gardeners can make predictions for production outcomes and revolutionize how they manage soil and grow success.

This kit is the only rapid microbial biomass test available. It offers supplies for ten tests, including extraction vials, disposable pipettes, extraction powder, a test card, a whisker, a soil sifter, a soil sampler, and capped measurer for quick, easy, and affordable soil testing in the palm of your hand.

I have a greenhouse that unfortunately does not get the ideal sunlight due to its location on the north side of my home. I have been using Rocky Mountain BioAg’s Quantum Growth Organic Total for over a year and have seen a dramatic increase in plant growth and vegetable yield compared to past years. Highly recommend the product.
