Cover Crops Benefit Soil Microbiology, including Fungus

Soil is alive…literally…and it hosts hundreds of thousands of different living organisms: insects,worms, microorganisms, bacteria, etc. Tilling in the old fashioned way strips life from the soil. Cover crops restore soil health and these different life forms are part of that important balance. Farmers realize that when the soil is happy, crops grown in the soil tend to thrive. Your soil, kind of like a dependent child, needs constant nurturing and healthy practices to grow strong and productive.

Part of that rich mix of life in the soil include Mycorrhizal Fungus. The fungi send out rootlike extensions (hyphae) which take up water and soil nutrients.  Plants produce sugars (polysaccharides) in their leaves and send them to the roots. Together, this symbiotic relationship produces a protein (glomalin) which captures and groups particles of organic matter, plant cells, bacteria and other fungi together. The soil takes on a crumbly texture, which creates the lightness and porosity that allows better drainage. Glomalin is a key part of important substances in promoting and stabilizing soil aggregates. It also aids in plant uptake of water and nutrients.
