  • Patent number: 11485689
    Abstract: The present disclosure concerns fertilizer particles comprising calcium nitrate and potassium nitrate. It is found that fertilizer particles comprising 43 to 47% w/w calcium nitrate and 46 to 54% w/w potassium nitrate can be produced by melt granulation. Due to undercooling problems, such particles were not expected to be suitable for industrial production by melt granulation. However, the present disclosure provides a composition which forms a low viscosity melt with short solidification time. This was successfully achieved by reducing the water content of a fertilizer melt comprising 43 to 47% w/w calcium nitrate and 46 to 54% w/w potassium nitrate to less than 3% w/w of the melt.

    Abstract: The uptake of foliar-applied metal ion nutrients, for example, zinc, iron, magnesium and copper, is influenced by humidity. Specifically, uptake is negatively impacted if the zinc is applied under low humidity, as the metal ion is “locked up” by leaf waxes as the droplet dries on the surface of the leaf, thereby rendering the metal ion useless. Described herein is a foliar metal ion fertilizer comprising (a) a metal ion sulphate in combination with a mixture of (b) urea and (c) a substance with a suitable point of deliquescence (POD) such as organic surfactants, calcium chloride, magnesium chloride or combinations thereof.

  • Patent number: 8617284
    Abstract: A macronutrient sustained release composition for a plant locus having nitrogen containing macronutrient compound adsorbed on the surface of hydroxyapatite phosphate nanoparticles, and a process for preparation thereof. The macronutrient adsorbed hydroxyapatite phosphate nanoparticles are encapsulated within cavities present in wood such that the biodegradation of the wood releases the adsorbed macronutrient compounds in a slow and sustained manner to the soil. Further, the macronutrient particles are encapsulated within the cell cavities of wood and wood is coated with cellulose modified hydroxyapatite phosphate nanoparticles such that the rupture of the nanocoating initiates the nitrogen release followed by the biodegradation of the wood releases the rest of the adsorbed macronutrient compounds in a slow and sustained manner to the soil.

  • Publication number: 20130283873
    Abstract: A dry flowable additive for aqueous urea-based fertilizers made of solid urea formaldehyde polymer (UFP), N-(n-butyl)thiophosphoric triamide (NBPT), and, optionally, dicyandiamide (DCD), wherein the liquid fertilizer containing the additive provides reduced nitrogen loss from the soil. Optionally, the dry additive may also be blended with molten or solid urea to form a solid urea-based fertilizer with reduced nitrogen loss from the soil.

  • Patent number: 8568506
    Abstract: An agricultural fertigation method includes the in situ manufacture of one or more fertilizers within the irrigation upstream of the agricultural field being irrigated. Co-reactant raw materials, namely sulfuric acid, phosphoric acid, nitric acid, potassium hydroxide, urea, ammonium hydroxide, ammonia, calcium nitrate and/or magnesium nitrate, are intermixed with each other and with the stream of the flowing irrigation water. The stream of flowing irrigation water dampens the resultant dissolution and reaction exotherms. A system wherein raw materials are efficiently fed to the irrigation system main line or a side-arm reactor efficiently implements the method.

  • Patent number: 8557013
    Abstract: The invention is directed to processes for treating biosolids that result in high-value, nitrogen-containing, slow-release, organically-augmented inorganic fertilizer that are competitive with less valuable or more costly conventional commercially manufactured fertilizers. The process involves conditioning traditional waste-water biosolids and processing the conditioned biosolids continuously in a high throughput manufacturing facility. The exothermic design and closed loop control of the primary reaction vessel decreases significantly the amount of power necessary to run a manufacturing facility. The process utilizes green technologies to facilitate decreased waste and enhanced air quality standards over traditional processing plants. The fertilizer produced from recovered biosolid waste is safe and meets or exceeds the United States Environment Protection Agency (USEPA) Class A and Exceptional Quality standards and is not subject to restrictions or regulations.

  • Patent number: 8491692
    Abstract: A water-dispersible particle is provided that includes organic origin potash in an amount ranging from 5% to 99.9% by weight of the total dry weight of the particle. A binder component is present in an amount from 1% to 95% by weight. The organic origin potash and the binder component on that contact with water causes particle dispersion into more than 100 pieces. A process for making a water-dispersible particle includes mechanical aggregation of the potash into a pellet. A binder component is present in the particle in an amount ranging from 1% to 95% by weight. The potash and the binder component are present in a form such that contact with water causes particle dispersion into more than 100 pieces. The pellet is then dried and ready to be applied.
