  • Patent number: 10947166
    Abstract: The present disclosure concerns a method for producing fertilizer particles comprising an alternative source of boron. It is found that certain colemanite and ulexite powders can be supplied to a fertilizer melt shortly before granulation essentially without dissolving into the melt. Accordingly, the fertilizer particles produced from the melt may contain negligible amounts or non-detectable levels of sodium borates or boric acid. Furthermore, the fertilizer particles can be homogeneous which is desirable for boron supplying fertilizers. It is also found that the fertilizer particles can supply boron to plants at a rate comparable to borax pentahydrate.

  • Publication number: 20140112999
    Abstract: Dissolved oxygen may be generated by adding a peroxide to a fluid stream and then catalytically decomposing the peroxide to generate oxygen. As the peroxide is catalytically decomposed, the oxygen may solubilize in a surrounding fluid so as to provide dissolved oxygen. In some examples, the amount of peroxide added to the fluid stream is controlled such that substantially all of the hydrogen peroxide added to the fluid stream catalytically decomposes and yet the dissolved oxygen concentration of the fluid stream does not exceed a dissolved oxygen saturation limit for the fluid stream.

  • Patent number: 8690984
    Abstract: An agricultural fertigation method includes the continuous introduction of concentrated raw materials into a high-dilution irrigation-water environment whereby the stream of flowing irrigation water dampens the resultant dissolution and reaction exotherms. A system wherein raw materials are efficiently continuously fed to the irrigation system main line or a side-arm reactor efficiently implements the method.

  • Patent number: 8679219
    Abstract: A process for preparing an elemental sulphur-containing fertilizer is disclosed. The process uses a dispersion mill, wherein a rotor turns within a slotted stator, to wet mill elemental sulphur in a liquid (preferably an aqueous liquid), thereby providing a dispersion of milled elemental sulphur in the liquid. The dispersion is combined with further components to provide a mixture of elemental sulphur and further components, and the mixture is granulated in a granulator unit to provide granulated elemental sulphur-containing fertilizer.

  • Patent number: 8628598
    Abstract: An agricultural fertigation method includes the continuous in situ manufacture of one or more fertilizers within the irrigation system 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 continuously fed to the irrigation system main line or a side-arm reactor efficiently implements the method.

  • Publication number: 20140000329
    Abstract: The invention relates to a particularly basic inorganic soil conditioner containing an inorganic carbonate as the base thereof, characterised in that it comprises at least one “dynamic disintegration” agent capable of causing a breakdown, considerable fragmentation, dispersion, and considerable “dispersion” within the granule, i.e. a force inside and/or on the surface of the granule that tends to cause the granule to break down or “explode” when said granule contacts the soil, and specifically contacts the water or moisture of the soil, and in that said carbonate is preferably natural or precipitated calcium carbonate.

  • 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.
