Ultrafine Mycorrhizae inoculum consists of 4 carefully selected species of endomycorrhizae. About 80% of the world’s plant species form with these types of mycorrhizae. These beneficial fungi greatly increase the effective rooting area of plants thereby enhancing plant growth, vigor and tolerance of environmental extremes. Ultrafine Mycorrhizae is a material containing mycorrhizal fungi that colonize roots and extend into the surrounding soil forming an essential link between plant and soil resources. They greatly increase the root’s ability to absorb water and nutrients, while improving plant survival, vigor and health.
