Spectrum™ contains a multiple species blend of plant growth promoting rhizobacteria (PGPR) and other beneficial plant growth promoting microorganisms (PGPs). This specially formulated soil inoculant enhances and restores beneficial soil microbe populations to augment the natural organic processes that occur in healthy soils. The beneficial soil-based microorganisms in Spectrum™ break down and release vital nutrients (such as phosphorus, nitrogen, calcium, iron, and more) stored in soil particles, making the nutrients more readily available to the plants in forms they can absorb. Plant growth-promoting microorganisms produce organic acids and amino acids, which dissolve and make available (chelate) mineral nutrients. Spectrum™ assists and speeds nature in decomposition and recycling of organic matter into an important substance known as humus, building richer, healthier soil. Apply at a rate of 50g/acre
