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.”
About Holganix: As the only true plant probiotics, Holganix Bio 800+ products contain an entire microbiome or community of organisms that is both abundant and diverse. In a single tote of Holganix Bio 800+ there are more than 800 species of active microbes, microbe food, and nutrient enhancers. Working together, the microbes in Holganix Bio 800+ unlock nutrients already present in the soil and optimize the uptake of nutrients you apply, maximizing nutrient efficiency and minimizing loss. Microbe food helps obtain the rapid establishment of beneficial microbes, while nutrient enhancers work with the microbes to promote strong root growth and healthier plants.

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.
Bright Endeavors Now (BEN) located in Tanzania, East Africa was started by Biology professor Dr. Regina Herbert, PhD and her husband, an Electrical Engineer, Ricardo R. Herbert, MUP, MBA.
The BEN program provides an environment where budding engineers, designers, scientists and doctors are introduced to concepts in the sciences, technology, engineering, art and math (STEAM), through engaging, developmentally-appropriate activities.

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.

Recently, microBIOMETER® was utilized as part of the “Soil and Microorganisms” series in their multi-age science class with students aged 3 to 15. Earlier in the school year, the students established Winogradsky Columns to observe microbial communities. The students then tested the soil with microBIOMETER® to see how specific ratios of fungi and bacteria can have an impact on soil health. In addition, it helped lead to a discussion on how different types of soil can have different ratios which can have an impact on how they grow plants and crops.
We love the microBIOMETER® soil test kit and will continue to test different samples with students as we travel to the US.” – Regina Herbert

The experiment was carried out at the location of the Agrovista LTD. trials site is near Lamport in Northamptonshire about 8 miles north of Northampton in the UK. It has a longitude of 52.372234, and latitude of -0.874273. The field site history is of arable farming rotations on a slightly southerly sloping topography.
“The tests, although time consuming, 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
