Why Soil Microbial Biomass Matters

Improving the health of your soil is essential to increasing your output, but how can you tell if you are making progress? Research shows that microbial biomass — fungi and bacteria — is the leading indicator of soil health. Living soil fixes nutrients, improves plant immunity, stores water more efficiently, and builds soil structure. A healthy level of microbes increases productivity while reducing inputs.

microBIOMETER® is a low-cost, 20-minute on-site soil test for microbial biomass and fungal-to-bacterial ratio that allows you to quickly determine the health of your soil using smartphone technology. Frequent retesting provides you with the data necessary to identify whether your soil management practices are working.

Whether you're a farmer, gardener, educator, or soil scientist, microBIOMETER® puts reliable soil biology data right in your hands — no lab wait times, no expensive equipment.

Why microBIOMETER®

  • Real-Time Soil Testing: Testing on field-moist soil provides data in real time, allowing for the most accurate results.
  • Track Management Effectiveness: Quickly assess how amendments impact soil microbial biomass, ensuring your management practices are effective.
  • Boost Regenerative Agriculture: Monitor changes in soil biology, increase carbon storage, and support sustainable farming practices.
  • Data Sharing: microBIOMETER® stores test data and locations in a cloud portal. View, edit, and export to Excel for analysis or sharing.
  • Team Projects: Create custom projects, invite team members, and share soil test results with custom fields, dates, and locations.

What People Are Saying

microBIOMETER® is a very efficient and time saving tool. It can be used by scientists, farmers, or a gardener in learning the microbial health of their soil. This testing process is also very non-invasive, and thus having a lesser negative environmental impact compared to traditional testing.

Dr. Anna Paltseva, University of Louisiana at Lafayette

I really love how clean, how clear the microBIOMETER® test is. What this test brings to the table simplifies the work for microscopists. We need tests that are reliable, that can synergize with other tests and give us the ability to look around a corner we couldn't look around before.

Matt Powers, Author, Educator, Citizen Scientist

microBIOMETER® provided an 'in field' test that when conducted well seems to suggest it is a reliable, consistent, replicable, and relatively simple test to evaluate soil biological activity.

David Purdy, Territory Business Manager at John Deere

We are so grateful for our partnership with microBIOMETER®! They offer a reliable soil testing product which we utilize in our Field Lab Kits. We greatly appreciate that we have a shared goal of making soil testing more accessible all over the world.
