Granular fertilizer compositions are described herein that are capable of supplying a wide array of beneficial nutrient and compounds to soil for uptake by the root systems of plants. In preferred embodiments, the compositions provide a source of phosphorus, a source of nitrogen, a source of boron, a source of copper, a source of manganese, a source of zinc, and a source of sulfur in a single application, with highly efficient uptake by plants. The compositions generally comprise a mixture of two or three types of granules, each providing a supply of one or more nutrients. It has been discovered that the components of the three types of granules interact in a synergistic manner, such that problems associated with certain nutrients in soil are overcome, thereby providing a highly efficient multi-nutrient fertilizer.

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.

The present disclosure is related to the development of improved fertilizer for precision and sustainable agriculture. A method was developed wherein efficient NPK nanocomposite for plant nutrition was synthesized in a single step using aerosol science and technology concepts. Further a formulation was prepared by addition of ZnO, TiO.sub.2 and other nanoparticles to the NPK nanocomposite. Also, an aerosol based foliar application technique was developed for the precise delivery of nanoparticles to the plants.

The present invention relates to the use of a fructooligosaccharide (FOS) comprising from 2 to 10 monosaccharide units, as an elicitor of the mechanisms of absorption of mineral elements from the soil, and of the defense mechanisms against pathogens. It also relates to a fertilizing and biostimulating composition containing these fructooligosaccharides, and to the use thereof in a method for treating crop plants.
