Soil microbial diversity and activity value (BIOTREX) is a value that measures both microbial diversity and activity.
This value is proprietary and has no other units.It is not intended to detect or count specific microorganisms.
Objectively evaluate how the microorganisms in the soil decompose organic matter as a whole under a constant environment.
Soil Microbial Diversity/Activity Value (BIOTREX) is a quantification of the diversity and level of organic matter decomposition activity of a microbial community.
It evaluates the ability of all microorganisms inhabiting the soil, making it possible to objectively evaluate the biological properties of the soil.
It is the only evaluation method in the world that was developed based on the results of about 20 years of research conducted by national and prefectural research institutes.
Diluted sample soil was placed in a test plate containing 95 different types of organic matter (food for microorganisms), and a dedicated robot was used to continuously measure the soil at a constant temperature at 15-minute intervals for 48 hours. Examine the rate at which each organic material is degraded by the microorganisms that live in the sample.
Since the types of organic matter that can be decomposed by microorganisms differ, the ability to decompose many kinds of organic matter means that there are many kinds of microorganisms.In addition, the fact that the decomposition rate of organic matter is fast means that microorganisms are working actively.
In this way, the value obtained by combining both microbial diversity and activity is the soil microbial diversity and activity value (BIOTREX).This value is our own, so there are no other units.It is not intended to detect or count specific bacteria.It objectively evaluates how the microorganisms in the soil decompose organic matter as a whole under a certain environment.The same method can be used to evaluate not only soil but also soil improvement materials and compost.
