Introduction
We developed MicroBIOMETER which estimates soil microbial biomass carbon and fungal to bacterial biomass in 10 minutes for $10. We correlate with chloroform fumigation extraction MBC, Pearson coefficent > 0.94. Go to microbiometer.com to find out more.

This updated version of how microBIOMETER estimates Fungal:Bacterial ratio and how the ratio was validated.
Climate extremes pose a global threat to crop security. Conservation agriculture is expected to offer substantial climate adaptation benefits. However, synergistic effects of conservation practices on yield during normal versus extreme climates and underlying regulatory mechanisms remain elusive. Here, we analyze 29-years of climate data, cotton (G...
White paper describing correlation of microBIOMETER estimation of microbial biomass with carbon fumigation extraction.
Understanding the plant's reliance of microbes for protection is key to appreciating that a healthy microbial population is key to cutting back on pesticides.
There a flaws and advantages to all the methods of calculating microbial biomass and its relationship to soil health. In this review I analyze the various methods for their usefulness.
Different concentrations of compost tea were used to assess the effect of concentration on sod health, via root mass, microbial biomass and nutrient levels at the end of the season. Microbial biomass was measured by microBiometer®. Concentration of compost tea correlated with root mass R2 = 0.98. Root mass correlated inversely with microbial biomas...
Methods and compositions for the preparation of soil samples and the determination of the number of microbes within a soil sample are disclosed. The methods include measuring, solubilizing, bleaching and filtering soil samples and measuring the turbidity of the filtered solution. The turbidity of the sample can be determined by visual inspection of...
A method of improving specific immune response to small immunogens, haptens, has been developed by changing the linkage between the hapten and carrier being used for immunization. High affinity antibodies to cotinine have been produced using this method. Antibodies to a glycated protein have also been developed, utilizing an immunogen which is comp...
A method of improving specific immune responses to small immunogens, haptens, has been developed by changing the linkage between the hapten and carrier being used for immunization. Antibodies to a glycated protein have been developed, utilizing an immunogen which is composed of a glycated peptide mimic of the glycated peptide sequence which is the...
Neural thread protein family is ubiquitous and shedding of brain ntp is correlated with Alzheimer and other neural activity conditions.
The invention is directed to preferred repeat sequences of Neural Thread Protein (NTP), peptides, mimetics, antibodies, and nucleic acids of the preferred sequences, and diagnostic and therapeutic methods of using such preferred NTP sequences.

A monoclonal antibody, Serex A93, recognizes peptide linked pyridinoline in Type I bone collagen fragments and can be used to quantitate bone resorption. The hybridoma producing this antibody has been deposited with the American Type Culture Collection, Rockville, Md., under accession number HB-12254. The epitope reactive with the antibody is stabl...
Abstract
A method and device are provided for the semi-quantitative and quantitative determination of an analyte in a sample. A non-competitive trap which can bind unreacted labelled receptor to analyte but has virtually no binding capabilities to receptor in the presence of analyte is used. Labelled receptor:analyte complex is trapped in a second...
Assays using receptor:reland complexes capable of releasing the reland in the presence of an analyte are described, wherein the reland does not detectably compete with analyte for binding to the receptor. The dissociation constant of the reland and the receptor is such that no appreciable release of reland occurs in the absence of analyte for the r...
A method of assaying for an analyte in a sample based on differential binding affinity involves detecting dissociation of a complex of receptor and ligand in the presence of analyyte. The receptor binds the analyte with high affinity and with the ligand with low affinity. The receptor-ligand complex may be formed in situ or may be preformed. In the...
The present invention relates to an integrated package-holder assay devices for detecting the presence of analyte in a sample. The device serves the dual roles of supporting and protecting an immunochromatographic assay. The device is compatible with any immunochromatographic assay format. The assay can be performed in a single apparatus for use in...
Abstract
An assay provides for detecting the presence of an analyte in a sample. Sample is applied to move through three zones. A mobilizeable receptor capable of binding to the analyte is present in the first zone. A trap for unbound receptor, consisting of immobilized ligand, is present in the second zone. Receptor bound to analyte will not bind...

Prolific Earth Sciences developed and markets microBIOMETER a rapid test for microbial biomass (MB) and fungal to bacterial ratio which we have shown correlated r = 0.94 with CFE. We want to fund an independent University study. That can be published. The study must include at least 50 agricultural soil samples that range from high MB to low MB and cover a wide variety of soil types. judy@microbiometer.com
Soil microbial biomass (MB) as estimated by microBIOMETER® has shown that it can measure soil health better than 6 of the popular soil health panels, or the PLFA and Haney respiration test (microBIOMETER® correlates r=0.96 with digitized microscopy estimation of MB). This indicates that MB provides information about soil health, not provided in these health panels. Since MB is low when physical characteristics of soil are poor, pH is low, and toxins are present, it would appear that the discrepancies between MB and soil health panels could be in the chemical analysis component of the panels. A possible explanation is that MB is an indicator of the bioavailability of soil nutrients and that this is not reflected by chemical analysis. We are looking to collaborate with researchers who could help us understand this phenomenon.
I want to have a booth at a prestigious soil health conference in Europe. Our product, microBIOMETER, is useful tool for monitoring regenerative and organic practices. We are looking for events that attract "influencers" and researchers.
I am studying the history of the soil respiration assay.
I am seeing a substance that looks like glomalin in my preps. I want to check if it is glomalin. Any ideas?
Soil samples that are high in fungal spores read high in a test we have for total microbial biomass but do not correlate with PLFA results.
I am dying fungi with dilution of sheaffer ink as described in the literature. Does anyone know the name of the dye used in this ink
If so, have you considered using MicroBiometerTM. See this 10 minute $10 test that correlates with PLFA at microbiometer.com
There are articles showing that microbial biomass is very high in vermicasts. I would be very interested in knowing if our test, MicroBiometerTM, microbiometer.com would be of use in your research and how it might help you.
When I read articles that claim to measure soil quality outcome, they cite as outcome increases in soil quality parameters. The real issue for farmers is whether and increase in these predicts crop yield. I have found very few articles that link these.
The carbon burst test is run in sealed jars on dried soil for up to 24 days. Doesn't this mean that the activity seen is by anaerobes?
