This concentrated formula of living microrganisms is the ultimate soil and plant inoculant. With 5 billion colony forming units of bacteria, it has the highest CFU count on the market. Its bacteria fix nitrogen from the air and solubilize minerals, helping plants increase root and shoot mass. It also keeps pests and pathogens at bay. This inoculant is fermented in the USA and contains strains of Paenibacillus Polymxa, Bacillus Subtilis, Bacillus Amyloliquefaciens, Bacillus Licheniformis, Bacillus Megaterium, Bacillus Thuringiensis, Bacillus Cereus, Pseudomonas Putida, and Pseudomonas Fluorescens.
