Carbon-complexed with Micro Carbon Technology®, OMRI-Listed Fertilgold® Soil is an organic soil product derived from amino acids, ferrous sulfate, manganese sulfate, and zinc sulfate (N 5.00%, Fe 0.10%, Mn 0.05%, and Zn 0.05%, with 29.0% organic matter). Fertilgold® Soil improves soil structure and enhances the beneficial soil microbial community. This balances the carbon-oxygen ratio, creating a carbon-rich soil with an active rhizosphere. Fertilgold® Soil increases availability of nutrients blocked by mineralization in soils and indirectly helps to diminish the stress of saline soils and pH extremes.
