Emil Racelis, a 6th grader in McAllen, Texas, utilized microBIOMETER® in his science fair project at IMAS (International Museum of Art & Science) and was awarded 3rd Place in the middle school division!
As a control, Emil tested three different store bought bagged soils with microBIOMETER®; top soil, organic potting soil and commercial potting soil. The top soil had a very low levels of microbes while the organic and commercial potting soils had a high level of microbes. Emil then collected soil samples in his community garden from areas with high plant diversity (five or more species in the sample plot) and areas of low plant diversity (areas with two or less species per sample plot).
His hypothesis was that areas with higher plant diversity would have more microbes, but that is not what he found. There were low/medium levels of microbes in all the plots sampled, therefore, no solid conclusion could be made. Emil believes the results stemmed from drought conditions they were currently experiencing in Texas. The garden was watered sometimes, but not that much. Emil would like to do more microBIOMETER® soil testing in the future during a season with more rain.
“I had a lot of fun using the tests and I got some pretty cool results even though they were not what I expected. I found the process really interesting and the test easy to perform. I hope I get to use microBIOMETER® again some day.” -Emil Racelis
“Emil really got into this project, and was fascinated by what he found, which only leads to more questions! Now he really wants to do more experimenting to see what helps the soil microbes. We have a garden, and he is talking about testing the results of compost tea, and other organic additives, as well as looking at the affect of drought vs rainy season. We may have to save up for more tests! You got us hooked! It was so cool to see him using the tests independently. I love how user-friendly your system is.” – Alison, Emil’s mom

Soil testing in Mexico
In the Pacific region of Mexico (state of Sinaloa), many vegetables are grown mainly for export to the United States and Canada. The soils in these crops have been greatly affected by the intensity of their management, which has unfortunately caused a considerable loss in their fertility and microbial biodiversity. In lieu of this, the use of biotechnologies based on microbial complexes is currently being highly promoted in order to inoculate the soils and recover part of the natural fertility. This is being performed alongside the use of other organic tools such as algae extracts, humic/fulvic acids, and liquid composts.
Mydagro LLC is using microBIOMETER® on vegetable plots where their biotechnology E-Microzyme (mix of beneficial bacteria) is inoculated into the soil. Their results have shown an increase in microorganisms and yield compared with the check plots. With the use of the microBIOMETER® soil test to measure the microbial increase quickly, it is now possible to better understand the behavior of microbiology and the positive effects of this type of horticultural crop.
“microBIOMETER® has proven that the use of biological and organic technologies can substantially help with the renewal of worn-out soils and gradually revitalize them to boost the productivity and health of the crops.” Fernando Cantu Galindo- Technical advisor Mydagro LLC Mexico
Drew Hundelt, Horticultural Specialist and Agroecology Practicioner, has partnered with Gibrill Sesay at Central University in Sierra Leone and microBIOMETER® is playing an important role in their work. Central University is a beautifully maintained college campus nestled in the lush tropical surroundings of Tonkolili in the Northern Provence.
Drew first became acquainted with Gibrill through the United States Department of State’s Community Engagement Exchange Program. The two spent some time at The Urban Farm in Denver facilitating agricultural programming for local neighborhoods. Shortly thereafter, their application to the reciprocal grant was approved which allowed Drew to visit Central University as an agricultural specialist in the Spring of 2023.
Utilizing the microBIOMETER®, Drew is currently working with the university on curriculum development around soil health in agriculture. Their most recent trials analyze how the effects of compost extract using soil from termite hills can bring about exponential growth and drought resistance to crops. The students are using the kit to get real time results of how the fungi to bacteria ratio can be a catalyst to real beneficial change.
“I had the opportunity to collaborate on several lectures and practicums for 30 students in the agricultural department. I spoke on the advantages of regenerative agriculture, community-built systems, and biologically driven yields. What struck me the most was the look in their eyes and how their spirit was teaming with curiosity. I knew then, initiated by the financial constraints of affording a commercial soil diagnostic lab, that I needed to get a biological tool into their hands to foster that curiosity. I am extremely hopeful about what the future holds for Central University, small-holder farmers in Sierra Leone, and West Africa at large. ” Drew Hundelt
Founded in 2003 UK based Wildflower Turf Ltd has pioneered and developed a soil-less growing system which has transformed the concept of turf growing.
Working with soils a fair bit, it being the substrate into which their products are grown, they are interested in understanding the relationship between plants and soil. This involves investigating things such as soil structure, nutrient content, and more recently microbial content, at their R&D testing facilities in Hampshire.
They know that microbe-rich soil is beneficial for plant health. However, is there a relationship operating in the other direction? Does having a healthy plant population, or a more diverse plant population like the kinds of habitats they are trying to create with their products, influence the soil community or the type and scale of microbial activity in the soil?
To investigate this, they used a microBIOMETER® kit to conduct a study into the difference in microbial biomass of soils under meadows compared to lawns.
The results suggested that increased species richness above ground supports a larger amount of microbial life in the soil below. The meadow areas they tested, where there was around 14 species per m2 on average, had 42% higher microbial biomass than the lawns, which consisted of only a handful of species, and a 60% increase in the amount of fungi was also seen. Microbial biomass was therefore found to be positively correlated with species richness. So, they can demonstrate that there is some kind of positive interaction between the species richness of the planting scheme and the life in the soil below. And this corroborates evidence from a number of similar studies which have shown positive relationships between plant species richness and various soil factors.
This is very interesting research which leads them to believe that you should be able to improve the health of your soil just by increasing the diversity of your plants. Because they know that the more microbes and fungi there are, the more ecosystem services the soil will be providing. There’s more work to be done here to investigate this relationship, but just from this brief study they have found that the soil-plant interaction is much more complex than they were giving it credit for, and the benefits of biodiverse planting schemes like wildflower spaces are also more myriad than they imagined.
Previously they had focused on the importance of wildflower reintroduction for improving aboveground biodiversity, in the form of habitat for insects and birds for example. But they are just beginning to understand how important this habitat is for its relationship with the soil as well. It is their hope that research like this will continue and eventually feed into recommendations like Biodiversity Net Gain (BNG) in the UK, and the many benefits of improving soil health through soil organisms.

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.”
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.
