Nitrogen fertilizer study at Ursinus College

University study demonstrates legumes are more efficient at improving soil MBC than grasses Under the direction of Assistant Professor Denise Finney, Kylie Cherneskie, biology student at Ursinus College, conducted an experiment on the impacts of nitrogen fertilizer addition on soil microbial communities. Kylie measured microbial responses using microBIOMETER®. Click here

Things you need to know about the Fungal to Bacterial Ratio (F:B)

microBIOMETER® is the only non-laboratory test for F:B. The methods of measuring F:B ratio give very different values 1-11. The Gold Standard for estimating fungal biomass is microscopy, which calculates fungal biovolume.  Note that microBIOMETER® detects the same range as microscopy- not surprising as it was validated by correlation with

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
