The Role Microbes Play in Increasing Soil Fertility

The microbial population or microbial biomass (MB) reflects soil fertility. For over 2 million years, plants and soil microbes have worked together to create what we call fertile “soil”. How do they work together? The plant supplies the microbes with carbon rich food. The microbes then mine the soil for

Soil Testing at the University of Louisiana at Lafayette

Last semester Soil Science and Environmental Pedology students under a supervision of Dr. Anna Paltseva [annapaltseva.com] conducted a soil microbial experiment on campus of University of Louisiana at Lafayette. First, each of the group of students collected different samples. Samples were collected from lawn, vegetable containers, around tree pits, and

Microbial Biomass vs. Microbial Respiration

What is the difference between microbial biomass (MB) and microbial respiration rate (RR) ? Both parameters are used to assess soil microbial health. The respiration assay measures the amount of carbon dioxide produced by the microbes in a given weight of soil. The soil is dried and then rewetted and

microBIOMETER® at Penn State University.

We began offering microBIOMETER® Academia Classroom Kits  last year and are excited with the interest we have received so far from universities, high schools and other academic institutions in the U.S. and abroad. Professors are utilizing our soil test to introduce their students to the world of microbes and soil

Carbon Sequestration

Increasing your soil microbes increases carbon sequestration. Carbon is stored in the soil as “humic materials” i.e. C,N,P,K etc.; rich organic matter which is the soil organic carbon or sequestered carbon in the soil. ­­­­­ The formation of humus, the final stable carbon, is a stepwise process. All organic carbon

Soil research using microBIOMETER®

Ben Lehman, research assistant in the Nutrient Management Spear Program at Cornell University, completed a study on the Within- Field Variability of Soil Characteristics and Corn Yield Stability on a New York Dairy Farm. Ben utilized microBIOMETER® in his research to determine the microbial biomass of the soil samples. This study was presented

Variance in soil samples explained

Often, we are asked about variance – different results when you test the same sample. Our answer is that nature produces most of this variance. To explain, when you measure out 0.5 cc of soil, you have on average about 0.6 grams of soil. If your microBIOMETER® results read 300ugMBC/gram

microBIOMETER® Soil Testing in New Zealand garden community

In learning how to develop healthy soil for healthy plants and people, Frans Plugge of New Zealand discovered the importance of increasing the fungi population in his garden and this led him to microBIOMETER®. “The microBIOMETER® soil test makes measuring the fungi to bacteria ratio so easy,” Frans said.  To

How do plants farm soil microbes?

UPDATE: Dr. White sat down with Dr. Fitzpatrick and Jeff Lowenfels to discuss rhizophagy. Click here to view the webinar. (Jan. 15, 2021) A summary of James F. White’s presentation at BioFarm, 2020 (Nov. 12, 2020).  The rhizophagy cycle is an amazing process recently discovered by James White’s laboratory at
