Nexia-O is a unique and distinctive blend of plant growth promoting rhizobacteria (PGPRs) in spore form. Once they become active they produce enzymes, organic acids, and other metabolites that increase the solubilization, availability, and uptake and utilization of nutrients such as nitrogen, phosphorus, and potassium. The PGPRs also provide many plant growth promoting responses like improved root development and establishment, and better emergence, crop stand, and stress tolerance. Nexia-O was designed for organic agricultural practices.
