The microcapsules, which may be applied to soil, seeds and/or plants, each have a shell that encapsulates an agricultural chemical, such as a fertilizer, herbicide or insecticide. One or more organosilane-coated magnetic nanoparticles is/are covalently bound into the shell of each microcapsule. For example, (3-aminopropyl) trimethylsilane-coated magnetite nanoparticles may be incorporated into the shell of a urea-formaldehyde (UF) microcapsule during in situ polymerization. In one embodiment, microcapsules encapsulating a fertilizer are applied during seed planting. Controlled release is subsequently triggered after an appropriate period of dormancy by positioning a magnetic field generating device proximate the microcapsules to generate a magnetic field sufficient to rupture the microcapsule shells through magnetic stimulation of the organosilane-coated magnetic nanoparticles.

  • Publication number: 20120036908
    Abstract: Fertilizers may include one or more additives that render the fertilizer more resistant to further processing such as thermal processing and/or aqueous-based processing that may otherwise be employed in the attempt to produce explosive materials from the fertilizer. The one or more additives may include materials that increase the chances of detection by providing a visual or olfactory indication of further processing. The one or more additives may include materials that make further processing more difficult or dangerous.

  • Patent number: 8110018
    Abstract: The invention relates to a fertilizer granule containing ammonium nitrate, comprising a core containing ammonium nitrate and a coating layer containing calcium sulphate. The coating layer consists of a mixture containing calcium sulphate and ammonium nitrate. Such a fertilizer granule is preferably produced by contacting the core with an aqueous ammonium nitrate solution and solid calcium sulphate particles, either as a slurry or separately. The production of the fertilizer granule is safe and easy.

  • Patent number: 8043995
    Abstract: Biodegradable anionic polymers are disclosed which include recurring polymeric subunits preferably made up of dicarboxylic monomers such as maleic anhydride, itaconic anhydride or citraconic anhydride. Free radical polymerization is used in the synthesis of the polymers. The polymers may be complexed with ions and/or mixed with fertilizers or seeds to yield agriculturally useful compositions. The preferred products of the invention may be applied foliarly or to the earth adjacent growing plants in order to enhance nutrient uptake by the plants.

  • Patent number: 8025709
    Abstract: Improved agriculturally useful products are provided, including solid materials such as nitrogenous fertilizers (e.g., urea), together with a polycarboxylated polymer selected from the group consisting of a salts of copolymers containing individual quantities of maleic and itaconic moieties. The polymer composition also includes from about 10-60% by weight of an organic drying agent such as a lower alcohol which enhances the quick drying properties thereof. The compositions may also include an amount of boron, and bimodal vinylic polymer made up of quantities of high and low molecular weight (MW) vinylic polymers such as PVA.

  • Publication number: 20110214465
    Abstract: A fertilizer composition including a base fertilizer granule with a barrier coating and one or more micronutrients. The base fertilizer material is coated with a barrier coating, and then a coating of one or more micronutrients. Alternatively, the base fertilizer material is coated with a barrier coating having discrete particles of micronutrients dispersed throughout. The barrier coating acts to physically and chemically isolate the micronutrient particles from the underlying fertilizer composition such that more of the micronutrient is available to the soil solution, and ultimately to the root zone of the plant.

  • Publication number: 20100326152
    Abstract: An encapsulated particle comprises a core particle and a polyurethane layer disposed about the core particle. The core particle can be various particles, such as fertilizer, biocides, flame retardants, seeds, etc. The polyurethane layer comprises the reaction product of an isocyanate component and an isocyanate-reactive component. The isocyanate-reactive component comprises a graft polyol having a continuous phase and polymeric particles. A method of forming the encapsulated particle comprises the steps of providing the core particle, applying the isocyanate and isocyanate-reactive components to the core particle, and reacting the isocyanate and isocyanate-reactive components to form the polyurethane layer. The encapsulated particle has excellent physical properties, such as increased water repellency, resiliency and shelf life.
