Humates are also a direct stimulant of the beneficial fungi called Mycorrhiza, which colonise the roots of host plants. Mycorrhizal fungi are organisms that live inside and outside root cells and help them reach for nutrients by extending long threads called “hyphae” into the soil.
The hyphae act as extensions of the root system sourcing nutrients for plants. Plants, in exchange, supply the fungi glucose and possibly other organic materials so the fungi can grow and in turn feed the plant. Predatory fungi control pathogenic nematodes by the production of mycelia, which invade their tissue and are then digested.
There is a tremendous value in the productivity and protection of Mycorrhiza microorganisms. Increases in growth production have been documented at 1600% for citrus, 4900% for grapes and 122% for soybeans.
By the release of more or less carbon compounds into the cortical root cells, the host plant can regulate the abundance of Mycorrhizal colonization from the plant root to the soil, thus increasing the growth and intensifying plant development along with crop yields.
