microBIOMETER is an on-site soil testing tool developed by Prolific Earth Sciences to measure microbial biomass and fungal to bacterial ratio in soil samples. The test, which takes approximately 20 minutes to complete, uses a patented method to extract microbes from soil particles. Users mix soil with a proprietary reagent solution, place drops of the mixture on a test card, and scan the card using a smartphone app. The app analyzes the color intensity of the microbes compared to a color comparator on the test card, providing results in micrograms of microbial carbon per gram of soil and fungal to bacterial ratios.
The company claims that microBIOMETER is faster, less expensive, and more accurate than traditional laboratory tests, as it allows for immediate testing of soil samples without the risk of microbial die-off during transport. The test has been validated through computerized analysis of microscopic images, showing a 95% correlation with the area of microbes in these images. microBIOMETER is designed to help users assess soil health, monitor the effectiveness of soil management practices, and make informed decisions about fertilizer use and soil amendments.
