There are billions of microbes in a handful of soil. 90% of these microbes are neutral; they don’t affect the soil toward disease or health when left on their own. However, according to Dr. Higa, in abused or diseased-chemical based soils, 5 to 10% of the overall colony is pathogenic made up of disease causing organisms. They steer the neutral microbes and create low productivity. Some soils are so bad that less than 1% of the organisms are beneficial.
