Katharhy G. is an agroecosystem and ethnoscience researcher who traveled to Ecuador to investigate the relationship between microbial biomass and crop health, as well as to study the local indigenous agriculture practices.
He visited 28 different farms growing 15 different crops. 14 of these farms are practicing conventional farming, while the other 14 farms are practicing indigenous regenerative farming. Most sites are not receiving irrigation. He tested the soil with microBIOMETER® and ranked the crop health as poor (1), average (2), good (3), excellent (4).
As the graph shows, microbial biomass correlated with crop health under all these different conditions. Samples with microbial biomass lower than 225 were all poor (1) and samples above 400 were all excellent.
The take home lesson is that to improve your plant health and yield, increase your microbial biomass by feeding your microbes with organic amendments.
