A device for granulation of concentrated and/or aqueous solutions/melts may include a shaft extending in a longitudinal direction and rotatably mounted within a housing. Impact arms may extend radially outward from a rotation axis of the shaft. Due to blade elements attached to the impact arms, particles of fluidized material to be treated may advance in the longitudinal direction along a flow direction and be rotated and mixed by the blade elements. A first blade element may have an attitude so as to be inclined relative to a plane that in a transverse direction extends through the rotation axis, when viewed in the conveying direction. A second blade element may have an attitude that is counter to the flow direction such that the second blade element when viewed in the conveying direction is aligned so as to be reversely inclined relative to a remainder of the blade elements.

A composition and method for producing an inorganic material with an inorganic coating. The inorganic coating may include ammonium sulfate. The present disclosure also provides a fertilizer having an inorganic coating. A method according to the present disclosure includes granulating an inorganic material and coating the organic material in situ with a reactive coating composition.

A stabilized ammonium humate mixture including an amount of humic acid between about 7.0% to about 10% of the mixture and an amount of ammonia between about 1.0% to about 14% of the mixture, where the remainder of the mixture is water. The stabilized ammonium humate mixture has a pH between about 9 to about 11.

An electric power generating system includes an autoclave coupled to a natural gas source, an oxygen source, and having a pressure reducing outlet valve. A high-pressure pump provides a solution of ammonium hydroxide and ammonium carbonate solution under pressure to the autoclave. An exothermic reaction generates high-pressure steam for electrical power generation. A crystallizer receives ammonium carbonate from the reaction for the formation of crystallized ammonium carbonate fertilizer.

High surface area magnesium carbonate structures formed from a calcined slurry of magnesium carbonate powder and a binder and method for their use to adsorb aqueous phosphate and ammonia for recovery and repurposing as a fertilizer are disclosed. A binder is utilized to aid in the formation of useful structures. The binder significantly increase porosity and the available surface area for adsorption.

A method of producing a fertiliser composition, the method comprising: (a) providing partially decomposed organic matter; (b) contacting the organic matter with: (i) an anaerobic digestate; (ii) a source of nitrate ion; (iii) a source of ammonia; and (c) contacting the mixture obtained in step (b) with a source of carbon dioxid. Also claimed is a fertiliser composition comprising partially decomposed organic matter admixed with an anaerobic digestate, a source of nitrate ion, a source of ammonia and carbon dioxide.

The present invention relates to a novel fertilizer with improved efficiency, and in particular with improved micronutrients supply, which furthermore is particularly suitable for near neutral and alkaline soils. The present invention further relates to a composite for a fertilizer containing a first particle containing one or more macronutrient(s) and second particle(s) containing a layered double hydroxide (LDH) containing at least one micronutrient; the second particle is present on the surface of the first particle.

The present invention provides a method for reducing plant water stress which comprises contacting plants with dry milled fibre, particularly wheat fibre and pea fibre. Said contacting is carried out in a manner selected from the group consisting of coating seeds with a mixture comprising dry milled fibre, pelletizing seeds with a mixture comprising dry milled fibre, applying a mixture comprising dry milled fibre in the form of granules, and applying a mixture comprising dry milled fibre in the form of tablets. Prior to said contacting, dry milled fibre is admixed with soil for plants, and the resulting mixture may optional comprise further additives such as fillers, binders, inert powders, colouring agents, fertilizers, fungicides, growth hormones, or microorganisms for inoculation.

A controlled release fertilizer has been prepared comprising a nutrient core coated with one or more moisture barrier coatings, at least one of said moisture barrier coatings comprising: at least one polyethylene wax; and a thermoset polyurethane from the reaction of a polyol and a polyisocyanate. The weight ratio of thermoset polyurethane to polyethylene wax is from about 50:50 to about 98:2. The polyethylene wax is heated above the melt point of the polyethylene wax and mixed and dispersed into the polyol component of the thermoset polyurethane in a ratio of 90-70% polyol to 10-30% polyethylene wax before the thermoset polyurethane-forming mixture is applied to the surface of the nutrient core and cured. A coating of a high temperature microcrystalline wax can be applied prior to final curing of the thermoset polyurethane to the coated nutrient core particles.
