Publication number: 20230140837Abstract: The invention is directed to fertilizers and manufacturing methods using organically enhanced inorganic fertilizer granules that incorporate a coating of one or more layers containing a bioactive agent in a carrier. The bioactive agent may be an herbicide, pesticide, plant growth regulator, microorganism, or beneficial element. Manufacture of conventional fertilizers involves stresses such as pH, heat, and pressure that are overcome by providing a protective carrier that facilitates and extends functional survival/effectiveness. Many carriers, such as liquefied dried milk, bind actively to the granule surface and contribute to the total carbon base. The release of the bioactive agent from the coating and or the surface of the fertilizer granule preferably results in a two-phased release, a first fast release and a second extended or slow-release into the soil metering the bioavailability of the bioactive agent for crop growth or protection, and/or for controlling unwanted vegetation or pests.Type: ApplicationFiled: January 12, 2022Publication date: May 4, 2023Applicant: Anuvia Plant Nutrients IP Holdings, LLCInventors: Jeffrey C. Burnham, Sanford A. Siegel, Martin M. Topps

Patent number: 11542213Abstract: The invention relates to a coated granular fertilizer, preferably wherein granules are sulfate-based or phosphate-based. When sulfate-based granules, as in ammonium sulfate, the coating substance is an inorganic salt of alkaline earth elements, preferably calcium, such that when applied to the surface of fertilizers, forms calcium sulfate, preferably a calcium sulfate-dihydrate, as a protective coating. For a reactive coating of a thiosulfate, free sulfuric acid present on the granule reacts to provide an elemental sulfur coating. For ammonium phosphate-based granules, coatings may comprise compounds of Ca++, Al+++ and/or Fe+++ salts thereby forming a calcium, an aluminum, an iron, or mixed cation phosphate protective coating. Thiosulfate is also effective with phosphate-based granules which are manufactured with sulfuric acid.Type: GrantFiled: December 18, 2020Date of Patent: January 3, 2023Assignee: Anuvia Plant Nutrients IP Holdings, LLCInventors: Sanford A.

Publication number: 20200148605Abstract: The invention is directed to coated fertilizer granules and methods for manufacturing granules and using organically enhanced inorganic fertilizer granules, which incorporate a coating of one or more concentric layers over a core such that the coating contains a bioactive agent such as a herbicide, pesticide, plant growth regulator, microorganism, or beneficial element. Application of the coating to the fertilizer granule preferably involves binding of the bioactive agent to the surface of granule or to the organic components within the granule. The release of the bioactive agent from the coating and or the surface of the granule preferably results in a two-phased release, a first fast release and a second extended or slow-release of the bioactive agent into the soil metering the bioavailability of the bioactive agent for crop growth or protection, and/or for controlling unwanted vegetation or pests.Type: ApplicationFiled: November 13, 2019Publication date: May 14, 2020Applicant: Anuvia Plant Nutrients CorporationInventors: Jeffrey C.
