BIOTREX in brief
BIOTREX was developed in Japan by Professor Kazunari Yokoyama, formerly of the National Agricultural Research Organisation, and commercialised by DGC Technology in 2010. The method has been utilized in over 20,000 cases and has gained adoption by numerous farmers, Agri input manufacturers, and local authorities.
The technique involves the utilization of a Microplate containing various carbon sources. Soil suspension is applied to the plate, and the rate and speed at which the soil microbial community (including bacteria and fungi) metabolizes the carbon sources are measured. This process is carried out continuously for 48 hours to simulate their workload. The outcome is presented as a single number.
