Mycorrhiza and Organic Fertilizers

Mycorrhiza: The Beneficial Fungus
 
Growing plants organically means feeding the soil rather than the plant. If you think about it makes since; when you feed and nourish the soil, the plant has available to it the entire spectrum of minerals and nutrients that it requires to thrive. In recent years mycorrhiza fungus has become more and more popular with gardeners. At our farm we use mycorrhiza fungus in everthing that we grow!

Mycorrhizal fungi are soil-dwelling, root-inhabiting, symbiotic fungi that colonize the fine absorbing roots of more than 95% of the land plants in the world. Various species of these fungi colonize tree and other plant roots to feed on the photosynthate (sugars) of the plants. In return for sugars, the fungi extend ‘feeding tubes’ called mycelia far into the soil. The plant gains the use of the mycelium’s tremendous surface area to absorb mineral nutrients from the soil. Some forms of mycorrhizae can increase the absorptive surface area of root systems by more than 700% compared to non-mycorrhizal roots. In addition, the mycorrhizal association allows the plant to access all of the 15 major and minor mineral elements, many of which are in forms unavailable to a non-colonized plant.

For instance, many gardeners are aware that phosphorous is an important nutrient that can become ‘locked up’ in the soil, and be unavailable to plants.  This “phosphate sink” occurs because phosphate ions are tightly bound to iron oxides in many soils, and plant root systems cannot access this important nutrient. However, mycorrhizae are able to absorb and transfer this form of phosphorus to their host plants. Through their alliance with plants, mycorrhizae increase the tolerance of their plant hosts to drought, compaction, high temperatures, heavy metals, soil salinity and toxicity, and adaptability to extremes of soil pH.

NOTE: A mycorrhiza (mycorrhyzae or mycorrhizas, Greek for” fungus root”) is a mutualistic (mutually beneficial) association between a fungus and a plant.
