A method for producing a soil enhancing compound is provided, comprising the steps of mechanically mixing a portion of composted agricultural waste consisting essentially of plant by-products, with a portion of bio-solid waste consisting essentially of sludge from waste water treatment, to form an organic compost mixture, and mechanically mixing with the organic compost mixture, a portion of industrial waste consisting essentially of calcium sulfate and phosphorous to form a final soil enhancing mixture, wherein a gelatinous, nutrient-containing substance is formed within the soil enhancing mixture by the interaction of the composted agricultural waste and the industrial waste. Alternatively, the agricultural waste can be used alone with the industrial waste. Either the agricultural waste, the bio-solids or the industrial waste may be acidic or alkaline, as long as the final soil enhancing mixture has a pH of between 6.0 and 7.5. If the radioactivity of the industrial waste exceeds permissible levels, the proportions of the other components in the final compound can be increased to dilute the radioactivity of the soil enhancing compound to acceptable levels.
