What are Mychorizae?
Mycorrhizae are symbiotic associations that form between the roots of most plant species and fungi. This symbiotic relationship is characterized by the equitable movement of sugars to the fungus and inorganic nutrients fixed by the fungi move into the plant, thereby providing a critical linkage between the plant root and soil. The fungal hyphae take up nutrients from soil solution and transport them to the root. By this mechanism, mycorrhizae increase the effective absorptive surface area of the plant. In nutrient-poor or moisture-deficient soils, nutrients taken up by the extramatrical hyphae (hyphea existing within soil matrix) can lead to improved plant growth and reproduction. As a result, mycorrhizal plants are often more competitive and better able to tolerate environmental stresses than nonmycorrhizal plants. Along the Colorado front range, mycorrhizal fungi are deficient in most soil types especially urban soils where new root infections post transplanting from the nursery are often zero.
