Efficiency of man-made and/or natural organic based animal manure fertilizers by liberating the bound nutrients (macro and micro) through the use of organic, non-aqueous liquid delivery formulations containing organic poly (organicacids) and/or their salts
The present invention relates to improving the efficacy of man-made and/or natural organic-based animal manure fertilizers by administration of an organic solvent formula containing polyorganic acids and/or their salts. The formulation liberates nutrient(s) that are normally bound in the soil as insoluble salts and complexes. These delivery formulations also provide an environmentally sound and inherently safe solvating system that improves diffusion of polyorganic acids to the granule fertilizer. These delivery formulations enable safe storage, transport and subsequent application or blending with solid or liquid fertilizers. The combined formulation and fertilizer can be applied to soil to provide improved efficacy of fertilizer by liberating nutrients bound in the soil for uptake by plant life.
