Mycorrhizal fungi form symbiotic associations with over 90% of the world’s plant species. They are particularly effective for agricultural plants that have high water and nutritional needs. Mycorrhizal fungi make nutrients available to growing plants, absorb water, retard disease, and condition soil. Research has documented improved plant nutrient and water uptake and resistance to a wide range of soil diseases and environmental extremes. Plants establish and yield more abundantly and require less intensive care. Over 50,000 University studies have highlighted the benefits of mycorrhizal colonization on the health and yield of plants. What is Mycorrhizae? “Mycor” – “rhiza” literally means “fungus” – “root” and defines the mutually benefiial relationship between the plant and root fungus. These specialized fungi colonize plant roots and extent far into the soil. Mycorrhizal fungal filaments in the soil are truly extensions of root systems and are more effective in nutrient and water absorption than the roots themsleves. More than 90% of plant species in natural areas form a symbiotic relationship with the beneficial mycorrhizal fungi. Why Mycorrihizae? Mycorrhizae can improve the soil structure, stimulate root growth, and feed the plant. Fertilizers cannot improve soil structure, prevent root disease, or absorb and store water. Fertilizers also result in water pollution, excess salt in the soil, and worsened soil stucture. Without mycorrhizae, plants will become dependent on fertilizers for survival and will not tolerate enviromental stresses well. Shipped US Postal Service.
