  • Publication number: 20200010382
    Abstract: 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.
