BioAg VAM, 2000 lb.VAM Endo Mix is BioAg's blend of endomycorrhizal fungi. In nature, these fungi form symbiotic relationships with plant roots; increasing the plants ability to access water and nutrients in the soil system. Our blend was designed to cover a wide array of plants that are compatible with the endomycorrhizal fungi. The fungi in VAM are mixed with humic acids as a start up food source. VAM works the best when applied directly to seeds or roots. Improves
