VA mycorrhizae
Vesicular Arbuscular Mycorrhizal Fungi: Glomus intraradices, Glomus etunicatum, Glomus deserticola, and Glomus clarum. Guaranteed a minimum of 3.52 propagules per g. Mycorrhizal presence equates to “Healthy Soils”. It affects available soil nutrition, the physical structure of the soil, and the number of and types of other organisms present in the soil. “Mycorrhizae” refers to the species of fungi that form beneficial associations with plants. It is a “Facilitator” that brings nutrients to plant roots, exudes “Glomalin” to improve soil structure, and actually fill up available entry sites along roots to inhibit pathogens from attacking. Mycorrhizal fungi are a critical component of healthy soils.
