Worm Power, a world leader in organic vermicompost products, helps growers improve crop yield and plant performance through increased root development and plant nutrient uptake. Worm Power’s Vermicompost Liquid Extract is shelf-stable soil amendment from liquid worm castings that have hundreds of diverse bacteria species.
The company currently utilizes the microBIOMETER® test to evaluate field trials on how their product is impacting the soil when compared to an untreated control. They like having the ability to show growers that the product is functioning as intended for increasing microbes in the soil.
Many specialty crops sterilize the soil to avoid pathogens. The addition of Worm Power’s products strives to bring soil back to a healthy and functional microbiome. microBIOMETER® provides the grower a visual measurement of the microbial community over time and the improvements gained with each application of their product. Healthy soils promote healthy plants and having a diverse microbe population is critical to this process and the microBIOMETER® provides a great tool to support their efforts.
“microBIOMETER® lets us see immediate results rather than waiting to see the increase in yield at the end of the season.”
Holganix utilizes the microBIOMETER® test as a baseline for their customers to see the fungi and bacteria levels present in their soil. These results act as a starting point. Most of the soil initially tested is bacteria dominant. That is what the company is trying to change. The Holganix product used to amend the soil is fungal and protozoa dominant. By increasing these levels, they are increasing the soil health on their customer’s farms.
microBIOMETER® acts as a dashboard or gauge that shows where growers start, where they are during the course of the season and where they are at the end of the season. Holganix uses this information to build a database that records year over year results; with the goal of increasing the biology in the soil.
These two photos from the microBIOMETER® app show one of their check fields vs. the same field with their product. This is an accurate representation of how they like to package the information for their growers.
“microBIOMETER® is a simple to use test that opens the eyes of our growers all across the Midwest. When they see the real time results, they begin to understand how important living biology is for their soil.”

There are many soil tests on the market so it can be difficult for farmers to ascertain whether or not they’re choosing the right one. The truth is, there are pros and cons to every soil test. Therefore, it boils down to finding which ones align best with your farming goals and which are easily and readily available to you without needing to stretch your resources too much.
Since microBIOMETER® is a relatively new soil test on the market, questions are often raised on how this test compares to other commonly used soil indicators such as the Haney Soil Test and PLFA test.

Since microBIOMETER® is a relatively new soil test on the market, a lot of questions are raised on how this test is different from other commonly used soil indicators such as the Haney Soil Test and PLFA test. While all three are soil biological health tests, their methodologies are very different and the tests measure different parameters.
The microBIOMETER® is an on-site soil test that measures the microbial biomass and fungal to bacterial ratio of living and dormant bacteria and fungi. The test process works by measuring the color intensity of the microbial solution created and comparing the color to the test card comparator. This patented, colorimetric analysis process is generated through our microBIOMETER® Reader App and produces results within 25 minutes of starting the testing process. Test prices range from $13.50/sample to $6.75/sample. The low cost, rapid result detection, and on-site testing of living soil are what makes this test stand out against others. The microBIOMETER® has a slightly limited scope, however, as it’s only able to measure the overall biomass of fungi and bacteria. It does not differentiate between microbial species nor does it measure any other parameters.
The Haney Soil Test is a lab test that focuses on assessing a variety of soil parameters such as pH, microbial biomass, water extractable organic carbon and nitrogen, soil respiration, and inorganic plant available nutrients such as NPK. This test uses multiple methods in order to obtain results, including the Solvita CO2 Burst test to indicate soil microbial respiration and biomass, and the use of unique soil extracts to determine organic and inorganic nutrient availability. While this test offers a large array of soil parameters, there is controversy in the science community about using the Solvita CO2 Burst test methodology as a way of accurately predicting microbial biomass. This is because the soil is dried then rewetted to trigger a release of CO2 to measure microbial activity. Drying soil decreases microbial biomass, and while rewetting it will increase biomass again, it doesn’t necessarily repopulate back to the original microbial composition. The Haney Soil test is offered at several labs throughout the country and recommendations are included with results. Generally, this lab test costs about $50/sample and takes about 3-4 weeks to receive results.
The PLFA Soil Test is a lab-based technique that analyzes phospholipid fatty acids (PLFA), which are found in the cell membranes of living organisms, to determine an estimation of living microbial biomass, fungal to bacterial ratio, and to identify the general presence or absence of microbial functional groups in bacteria, fungi, and protozoa. For this test, labs first dry the soil overnight then use multiple solvents to extract fatty acids from the sample. Then, mass spectrometry is used to identify the sample’s microbial composition based on specific PLFA biomarkers. This testing process takes a few days to complete and generally costs about $60/sample depending on the lab. It is one of the most utilized testing methods since it gained popularity in the late 80’s. Since then, it was discovered that some of the PLFA biomarkers used for identification aren’t limited to one microbial group, therefore making it difficult to determine the accuracy of some results.
The value of each of these tests is to determine a baseline assessment of your soil health. The information obtained from any of these tests will help you gain a better and more rounded understanding of what’s happening in your soil.
David Purdy,, Territory Business Manager at John Deere and Soil Health Specialist, utilized the microBIOMETER® soil test in his study titled Assessment of the mircoBIOMETER Soil Biology Test for Agrovista LTD.
Background:
There is an increased level of interest in soil health and a greater demand for more analytical approaches, in particularly for soil biology, for its assessment from farmers and advisors. This short report reviews the use of a recently developed rapid on-site soil microbial carbon testing tool called microBIOMETER® using a replicated 5 year cover crop experiment.
Founded in 2008, Applied Bio-Minerals, Inc. specializes in managing naturally present microbiomes using mixtures of mined minerals.
The company’s operating mode is based on observations, and a close collaboration with the customer. The holistic approach enables farmers to use microbes already present on their farm to their benefit by lowering their inputs and maximizing their revenues, all naturally. As part of the service provided to customers, the company regularly measures progress to ensure the farmer’s goals are met.
Their approach is to examine the entire living soil profile and record its evolution from a baseline set before the application of products. Among the many variables one is essential, the amount of living micro-organisms, and the ratio between bacteria and fungi, at various soil depths.
That is where microBIOMETER® comes in. They have been utilizing the microBIOMETER® soil test in their business since 2020.
“microBIOMETER® is a very convenient tool to have a quick result (in the field) on microbes and allows decisions and adjustments in conducting the field as the season progresses or from one season to the next. Microbial life might sometimes be surprisingly active in depth (here a vineyard). The importance of checking compost quality also underlines the usefulness of the microBIOMETER®” – Herve Bonin, co-founder and managing partner of Applied Bio-Minerals, Inc.
