Bucknell University is a private liberal arts college in Lewisburg, Pennsylvania with excellent research facilities and innovative teaching. Students get the opportunity to work closely with professors in their chosen field.
Students in the Biology 203, Integrative Concepts in Biology, laboratory have a unit all about soil. The students visit the Bucknell Farm to learn about the properties of healthy soil. They then pick a location on campus to study. Students study the health of the soil in different conditions, such as soil with native flowers growing compared to soil under a tree. They measure microbial biomass, soil respiration rate, and various other soil properties to determine the overall health of the soil.
“The microBIOMETER® test allows students to quickly and easily measure microbial biomass and the relative amounts of bacteria and fungi in the soil. It is easy to use for non-experts with very quick results! We have measured huge differences in the microbial biomass at locations across Bucknell’s campus and have been surprised to have very high levels of biomass in the grassy areas, too!” – Rebekah Stevenson, Director of Core Course Laboratories – Biology Department
Overton Environmental Enterprises, Inc. is a Canadian company that develops innovative biotechnology solutions that reduce reliance on chemical fertilizers and pesticides.
Their EcoTea™ products and research are focused on helping farmers work with soil ecosystems instead of against them. In their years of research they have proven direct results from using broad spectrum biology but the impacts in the soil and changes in soil quality have been harder to showcase.
Three seasons ago they discovered the microBIOMETER® testing system. These tests have given them a way to benchmark pre application conditions, the post application changes and most importantly the improvements over time. This real-time way for farmers to see the unseeable has given them confidence in the value of biology for their soils and programs. They use microBIOMETER® to augment field data (i.e. help correlate scores with plant health data and yield). microBIOMETER® has allowed them to show how EcoTea™ can influence root bacterial to fungal ratios and determine (at least in part) the amount of resources the plant is allocating to the rhizosphere.
The microBIOMETER® has given us another way to showcase how re-introducing biology can help our soils and the hard-working communities that rely on them.”

Amanda Foxon-Hill, a chemist by trade, is working with Mid Lachlan Landcare in the region of NSW, Australia. Mid Lachlan Landcare is a community organization committed to the regeneration of land. Their work includes Regenerative Agriculture, Box Gum Woodland Conservation, Superb Parrot Habitat, Community Gardens, Education & more. Cowra is the main town in their Landcare region which consists of various soil profiles. It is rich in farming land with cropping and grazing.
Amanda designed and performed a soil research project funded by the BCT (Biodiversity Conservation Trust). She took soil samples from farms, conservations and public land across the region to map their soil microbiome. Her goal was to see if she could establish a ’normal’ or ’typical’ range of microbes for each type of landscape and soil.
Amanda looked at grazed vs ungrazed land, mono-cropping vs mixed pasture etc. but that was really secondary to the soil geology and microbe link as there was a short window to complete this round of tests and farm management decisions such as what crop to grow, for instance, requires testing over multiple time points.
As part of the project, Amanda trialed microBIOMETER®. Microbes are essential for soil fertility and almost all plants work cooperatively with microbes to access the nutrients they need to thrive. The relationship between plants and microbes is dynamic; changing with the season, how the land is managed, plant species and life-stage, climate and the soil structure and composition.
“Overall, we feel this project has successfully delivered insights into how the Mid Lachlan region’s soils microbiome functions with respect to landscape features and management decisions although it’s clear there’s still a lot more work to do. Also, after putting the microBIOMETER® through its paces we believe it’s a useful tool for those looking to gain a deeper understanding of their soil. Our advice would be to use the microBIOMETER® or similar microbiology assessment tool/ protocol alongside your existing soil testing tools, at regular intervals to monitor the effect management decisions have on the soil microbiota over time.”

Ithaca Central High School science teacher Robert Tuori is conducting a study to examine short term changes in soil health at Nook And Cranny Farm, a diverse vegetable farm, as an independent research project for the USDA Climate Change Adaptation and Mitigation Fellows.
Utilizing both the microBIOMETER® and Cornell Soil Health Assessment, Robert and students will compare tilled vs non-tilled soil in 4 crop beds, each containing either brassica or cucurbit, and flipping crops midseason. The beds were covered in October of last year with a cocktail of winter rye, vetch, and triticale. These cover crops were grown until early May, then covered with a black silage tarp for one month. The brassicas were planted into hay mulch while the cucurbits were planted into biodegradable plastic mulch.
Robert is particularly interested in looking at easy, on-farm testing, as well as lab analysis. They will conduct microBIOMETER® testing on each bed three times throughout the season: before planting, midseason before second planting, and at the end of the season. For the lab based analysis, they will measure nutrient levels in each bed at the beginning and at the end of the study, as well as perform the Cornell Soil Health Assessment on all four beds at the end of the study.
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.
