microBIOMETER® testing soil and compost in the Netherlands

With a small R & D grant awarded from the Dutch government, Jo Ploumen of the Netherlands is using microBIOMETER® to determine fungal to bacterial ratios in vermicompost filled in a Johnson-Su Bioreactor versus residence time. Jo also uses microBIOMETER® to measure microbes and F:B ratio in select soil samples

Soil Health Improvement Tracking

Microbial biomass (MB) is the best single indicator of soil health (Doran, 2000). Microbes feed and protect plants, build soil structure which prevents erosion, increase water holding capacity, and build soil organic matter (SOM). MB is low in any situation that is harmful to plant growth (and vice versa) and

Why is microBIOMETER® the best test for soil health?

Until now tests for microbial biomass were expensive and time consuming. microBIOMETER® costs $13.50 or less and takes 20 minutes with results read by your cell phone. * Only microBIOMETER® identified soil health in a U. of Tennessee study of soil health test methods including Cornell, USDA, Alabama and other

“Farming is more fun with microBIOMETER®.”

microBIOMETER® helping increase soil health in Brazil. Marcelo Chiappetta of Chiappetta Agricultural Company in Brazil shared with us how microBIOMETER® is assisting them with their soil management efforts. Their main agricultural crops are soybeans and corn. Between those crops, as they have a temperate climate during the winter months in

Does microBIOMETER® measure dead microbes?

We receive this question often and the answer is no. How do we know this? microBIOMETER® shows that soil removed from the earth and plants lose microbial biomass every day which we have confirmed with microscopic studies. The literature also confirms this. Why is there confusion? Most of the microbes

How does microBIOMETER® measure microbes?

Soil microbes are tightly bound to and often covered in soil making them very hard to evaluate by microscopy. The special magic of microBIOMETER® is the extraction powder and whisking process that separates most of the microbes from the soil. And during the 20 minute settling time allows the soil

How Do Arbuscular Mycorrhizal Fungi Promote Plant Growth?

Arbuscular mycorrhizal fungi (AMF) penetrate the root and establish little areas in plant root cells where they can exchange nutrients with the plant. AMF improves the nutrients available to the plant by collecting soil minerals such as phosphorous, nitrogen, magnesium and manganese through an extensive network of fine fibers (hyphae)

What is a good level of soil microbial biomass?

Understanding Soil Organic Matter and its impact on soil health and microbial biomass. We are often asked what is a good level of microbial biomass (MB). There is no one answer. The level of MB you can reach is dependent on soil organic matter (SOM.) Soil organic carbon (SOC) is

Choosing an Arbuscular Mycorrhizal Fungi for your Plant

Arbuscular Mycorrhizal Fungi (AMF) colonize 80% of crops. Their effect on plant growth can be positive, neutral or negative. It depends on many factors including the crop species and genotype, the species of AMF, and the characteristics of the soil. A low pH favors colonization of the plant by AMF
