Humate is a soil conditioner containing a high concentration of trace minerals and humic acid. Humate improves a plant’s ability to take in vital nutrients, helps in root and plant cell development, improves soil structure, enhances germination and increases resistance to stress. It also provides the micro nutrients necessary for healthy, balanced plant growth.

MycoApply® Ultrafine Endo

MycoApply® Ultrafine Endo is a suspendable powder mycorrhizal inoculum consisting of 4 species of endomycorrhizal fungi. About 85% of the world’s plant species form symbiotic relationships with this type of symbiotic soil fungus. These beneficial fungi greatly increase the effective rooting area of plants, thereby enhancing plant growth, vigor, and tolerance of environmental extremes. MycoApply® Ultrafine Endo is a concentrated, fine, suspendable material with a particle size less than 300 microns (will pass a #50 screen) containing mycorrhizal propagules, which colonize roots and extend into the surrounding soil forming an essential link between plants and soil resources. Increasing the rooting area allows improved access to water and nutrients, promoting plant quality and crop performance.

Suspendable Powder Formulation:
• 4 species Endomycorrhizae
• Glomus intraradices, Glomus mosseae, Glomus aggregatum, Glomus etunicatum
• 130,000 Endomycorrhizal Propagules per lb.

Package Options:
