How alive is your soil?
Replaces costly lab tests with real time testing on living soil
Monitors the effectiveness of your soil amendments
Fights climate change through knowledge and awareness
microBIOMETER@ is a 20-minute on-site soil test to determine microbial biomass and fungal to bacterial ratio. This lab grade soil test is simple to perform with rapid results. It’s faster, less expensive and more accurate than sending your soil to labs because microbes start dying once they are removed from the earth.
How does it work?
Soil microbes secrete a substance that binds non-living soil particles to each other and to themselves. Our patented method extracts the microbes from the bound soil particles which then settle to the bottom. The soil-colored microbes remain suspended in the fluid and are sampled. The sample is placed on a testcard which is scanned using a smartphone. Our smartphone application measures the color intensity of the microbes as compared to a color comparator surround on the testcard.
How did you validate the accuracy of the microBIOMETER@ results?
The results were validated using a computerized analysis of numerous microscopic images of microBIOMETER® extracts from many different soils. We found a 95% correlation with the area of the microbes in these images and the results reported for microbial biomass and fungal to bacterial ratios using microBIOMETER®.
What does microBIOMETER® tell us?
- The higher the microbial biomass, the more nutrients available to your plant naturally, decreasing or eliminating the need for chemical fertilizers.
- Microbes, especially fungi, are building soil structure which prevents erosion.
- If microbial biomass decreases after applying chemical fertilizer, you have used too much.
- F:B ratio of rhizosome soil will tell you if arbuscular mycorrhizal fungi (AMF) have colonized your plant making it more resistant to drought and pests.
- An increase in the F:B ratio indicates the green manure you used is optimal.
- Soil organic carbon is mainly the bodies of dead microbes, so if you are not increasing your microbes you are not building soil health or sequestering carbon.
- A rapid increase in MB indicates the effectiveness of cover crops and amendments.
