microBIOMETER® can tell you if you are increasing the nutrient value and disease resistance of your crop.
A Rodale study showed greatly increased levels of the vitamins and minerals in sustainably farmed soils as opposed to mineral fertilized crops. And at Rodale, the sustainable practice yields are the same as the paired fields farmed with mineral fertilizers – and in bad weather, and disease years significantly better. Rodale is only one of many studies showing the increased nutrient value of organically and sustainably grown food.
Now Dr. Montgomery of the University of Washington’s team in a similar study has shown that if you are increasing your microbial biomass you are increasing the nutrient level of your crop: “soil health is a more pertinent metric for assessing the impact of farming practices on the nutrient composition of crops”.

Different methods measure different fungal and bacterial populations. The chart below, adapted from Wang et al review of 192 different F:B ratios, illustrates how three different methods came up with three different F:B ratios for Forest, Farmland and Grassland. Note that microBIOMETER® correlates well with the gold standard, microscopy. By plate culture, forest F:B is about 1/3 that of farmland, whereas PLFA forest F:B is slightly higher, and microscopy and microBIOMETER® forest F:B are 10 times higher than farmland.
Nature article reports that microbial biomass estimates by microBIOMETER® correlates with soil health and yield stability.
The microBIOMETER® soil test was used to report microbial biomass in a recent Nature publication*. Scientists Dr. Judith Fitzpatrick and Dr. Brady Trexler of microBIOMETER® collaborated with a University of Tennessee team headed by Dr. Amin Nouri. The team evaluated the effects on soil health and yield stability of 39 different methods of raising cotton over 29 years. The conditions tested included till, no-till, various cover crops and different levels of nitrogen fertilization.
The study found that the major impacts on yield were very dry or wet conditions, and low or high temperatures. The deleterious effects of these weather extremes on yield were mitigated by regenerative agricultural practices which resulted in adequate soil, C, N, soil structure and microbial biomass.

Austin testing soil testing at a hemp farm with microBIOMETER®
PLANT Group is a team of designers, engineers, and ecologists. The company is building systems to connect humans and nature. In the process, they are soil testing at a hemp farm in Iowa, Honeysuckle Hops & Hemp.
First, through their partnership with Blue Forest Farms, the team at PLANT Group is using microBIOMETER®. They are utilizing the tool to research soil health and carbon sequestration implications of growing hemp.
Furthermore, Austin has an interest in publishing research on their alternate organic hemp production methods. microBIOMETER® is assisting them in collecting some “pretty cool data on microbial biomass and fungal ratios in the soil in response to these strategies.”
Meanwhile, the company recently launched a new line of hemp food products, Hemp Hearts. They grow each plant regeneratively. This includes a focus on soil carbon, biodiversity, and ecosystem health.
Did you know one hectare of hemp can absorb 15 tons of CO2 per hectare? Hemp’s rapid growth makes it one of the fastest CO2-to-biomass conversion tools available. Therefore, let’s stop cutting down our forests. Plant some hemp instead!
Lastly, please visit the PLANT Group website to meet the rest of the team and learn more about their business. And follow them on Instagram to keep up to date on their progress!

Chiappetta Agricultural Company
We were excited to hear from our long-time customer Marcelo Chiappetta of Chiappetta Agricultural Company on how his microBIOMETER® testing has been progressing. Below is what he shared with us.
“Here in southern Brazil the past 5 years we’ve been working with biological agriculture and changing the way we see and manage our farm; more and more like an agricultural organism. Taking care of microorganisms, plants, animals and humans and focusing on producing high quality grains.
Fungal and bacterial ratio is fundamental to know how our soil is related to what crop we grow. And now, after starting to brew compost tea and using compost extract, microBIOMETER® is helping us measure and understand the right recipe of carbon and nitrogen related to the amount of fungi that we want to build in our composts before adding to the soil. We see that good microbial biomass along with organic matter is excellent for our soils.
In practical terms, we see biological flowering in crop fields and this is the proof that we are doing a great job with nature. Our soil is our bioreactor, and we need to feed it with the right nutrients. The Brazilian biome is rich on biodiversity and as farmers and soil guardians we have a responsibility to bring life back to our farm again in a sustainable way of producing food.”

Soil testing
Modern agriculture practices have led to the systematic degradation of the world’s soil and release of carbon into the environment. The effects are increased need for expensive and environmentally dangerous inputs (fertilizers, pesticides, and herbicides), the loss of fertile top soil, decrease in water holding capacity of soil and dangerously high levels of atmospheric carbon.
Farmers, industry, and environmentalists are looking for cost-effective and reliable ways to measure soil health, to assess impacts of progressive changes on soil and harvest management, and to measure carbon in soil. Before microBIOMETER®, growers have traditionally relied on expensive lab testing of soil. Many current methods are technique and individual lab dependent. Therefore, run-to-run and lab-to-lab variation can greatly affect consistency leading to increased variability. Current methods are performed in labs and the soil is aged and changed from the time of collection. Furthermore, lab tests are difficult to use in developing countries as they can cost upwards of $500 per sample. This makes the test prohibitive to some markets and limits the number of times a grower can test their soil.
Our mission at Prolific Earth Sciences is to enable soil stewards all over the world to use mobile technology and our low-cost soil test to assess regenerative soil practices, to improve soil health, and work towards increased soil carbon sequestration. microBIOMETER® equips growers with the data necessary to make decisions on which practices are the most cost-effective. Inputs such as fertilizers are expensive and changes to practice are risky. Monitoring soil microbial biomass inexpensively, in real time, can help a soil steward quickly assess if an input and practice is improving soil health and worth the investment. In other words, assess before you invest! We also envision microBIOMETER® one day being a powerful tool in the measurement and audit of carbon sequestration programs.
microBIOMETER® has been on the market for over 3 years with direct and distributor sales and currently has customers in over 20 countries.
Graham Mackie, Golf Course Manager at Edzell Golf Course in the U.K., has been using microBIOMETER® to monitor the health of the soil on the greens. Here is what he had to say about our soil test.
“I really like microBIOMETER®. It is simple to use and for the first time I can get baseline readings to see what is effective and what is not in influencing soil biology. As a golf course manager I believe that swinging the F: B ratio in favor of the fungi will allow the dominant grasses to be the desirable perennials.
I took microBIOMETER® readings of the main 18- hole course as well as the small 9-hole course and the readings correlated with what I expected. The 9-hole greens have more poa annua, therefore, were more bacterial dominant. I also took a reading of an area of untouched fescue rough which was very fungal dominant, as expected. It was great to have this theory confirmed. I am now looking forward to see if and how I can swing the balance to more fungal dominance on the greens.”
A BIG thank you to Graham for sharing his testing experience with us!
Sustainable Organic Q8 was launched in mid-2018, educating people on recycling their organic waste, being environmentally aware and teaching people how to grow whatever and wherever they can. As far as gardening/farming styles, Sustainable Organic focuses on the value of the living soil and the soil food web and teaching home gardeners and farmers to slowly shift the general culture from MONOCULTURE, “Babysitting plants” and providing all their needs from nutrients to medicine to DIVERSITY, Building and regenerating an ecosystem that will take care of itself or at least be a bit less exhaustive and much more sustainable.
Sustainable Organic has helped bring diversity above grounds back to the region in the past couple years. However, many people are still very new to the life underground and living soil. Their gardening/farming practices rely heavily on providing nutrients and immunity/medicine to plants. To them it is cheap, it works, and they’re so set in their ways that the idea of change is becomes a source of anxiety.
Although more and more gardeners are praising the life in the soil, they also practice routine solarization and refuse to refrain from it, reflecting their hazy understanding of soil biology and the soil food web and what it really takes to construct. Testing the soil to most growers means checking nutrient availability, water content and pH.
For the sake of adding some objectivity to soil biomass and increasing the value of soil biomass testing, Sustainable Organic sent microBIOMETER® test kits to popular gardeners in Kuwait, Saudi and Dubai to experiment with by testing their soils and compost. These gardeners have a large number of followers and they educate via social media, gardening courses, and workshops. By starting to broadcast microBIOMETER® as a means of testing the biomass in the soil and amending it based on the readings received, Sustainable Organic intends to create a trend in the region shifting the focus more on the life in the soil than the mineral content.
“microBIOMETER® is an innovation that has made it possible to quantify the life in the soil. This economic tool, I believe, not only helps us improve our soil at the gardening/farming level, but it can also help us deepen our understanding and comprehension of the soil food web and the LIFE underground. This will ultimately lead to a tremendous positive change at the psychological and behavioral level. It’s common to see people in our region praising the life in the soil (finally), but then professing solarization at the end of or the beginning of a grow season. This is an obvious clash in concepts that we hope are not deeply understood. We believe with popularizing the use of the microBIOMETER®, we can help clear the fog!
It’s beautiful to see people go out in the middle of the desert and start digging holes to “build” soil, plant trees and mulch around them; then announce seeing mushrooms and biologic diversity; start talking about soil biology, arbuscular fungi and carbon sequestration and tell farmers near them to try out the living soil method learned from Sustainable Organic. They say think globally and act locally. We intend to revive the desert in the Arabian Peninsula with Mother Earth and her fever at heart!”
About Dr. Jassem Bastaki. Originally from Kuwait, Jassem acquired his education in Head and Neck Endocrine Pathology in Pittsburgh, PA. In 2012, he left Pittsburgh to practice diagnostics and oncology in Kuwait and in doing so transitioned from fertile land to urban settings in some of the harshest climates in the world. The stress from his line of work led him back to gardening; indoors and hydroponic initially until he learned how to garden outdoors no matter the climate or conditions. Every second he spent with his plants taught him more and more about life and the reality we are unaware of. “We are guests on this earth with everything else that lives on it and in it.” The more he realized what was missing and where to find it, he wanted to help everyone find their way back to earth.
Jassem is a microBIOMETER® distributor in the Gulf Region as well as Iraq, Jordan and Egypt.

Ben Taylor-Davies, also known as Regen Ben, is a farmer and bioagri-ecologist working from Herefordshire in the UK. His farm is based in Ross-on-Wye and has been focused on environmental improvements for the past 22 years. His work includes creating 12km of new hedges with 6m of pollen and nectar or ground bird nesting margins around every field as well as working on river meadow restoration.
Following a Nuffield scholarship in 2016 and the opportunity to travel the world (USA, Canada, Brazil, Argentina, Uruguay, Paraguay, Chile, Peru, South Africa, France, Belgium, Germany, Poland, Ukraine, Belarus, Russia, Mongolia, China, Singapore and Australia), Ben was intrigued by the regenerative agriculture movement which very much complimented the environmental work he was doing back on his own farm. When discussing these soil health focused farming methods with clients as an agronomist, it struck a chord with many of them too; the future of agriculture and real farm sustainability.
Ben came across microBIOMETER® in 2019 and found it an incredibly useful tool in benchmarking clients farms in order to start monitoring change in what they were doing. The real time results offered by microBIOMETER® provides Ben with full control over how, where and when he takes readings. Ben uses his microBIOMETER® readings in conjunction with the What3words app which allows him to accurately repeat measurements in subsequent years in order to build a picture of successes and failures.
