Abstract: The invention relates to a process for producing a controlled release fertilizer of potassium chloride comprising the following steps: a. providing compacted KCl, having a sphericity of below 0.87; b. dry polishing the KCl in an intensive mixer type device consisting of a container vessel and at least one set of agitating elements such that the KCl has a sphericity of between 0.88 and 0.92; c. providing a coating on said polished KCl. The polished and coated compacted KCl can show with 6 pph coating a release of about 18% after 7 days measured with a water leach test at 21 C. The polished and coated compacted KCl may have one or more of the following release properties: a release at 10 days of about 20% or less; and/or a release at 30 days of 40% or less; and/or a release at 50 days of 50% or less.

Abstract: Granular compositions comprising at least one herbicide that inhibits microtubule assembly, at least one herbicide that inhibits cell wall synthesis, and a surfactant, and methods for making and using such compositions, are generally described.

Abstract: A process for producing a coated particle to provide controlled release characteristics. In this process the mixing of the substrate and coating is made in a mixing device and that mixture is then transferred to a reactor vessel different from the mixing device where the chemical curing of the coating over the particles takes place. Several layers of coating can be applied by repeating the steps and it can be run in a fully continuous manner.

Abstract: Fluid injection systems and methods, particularly, fluid injection systems and methods for use in fertigation and irrigation.

Abstract: Granular compositions comprising at least one herbicide that inhibits microtubule assembly, at least one herbicide that inhibits cell wall synthesis, and a surfactant, and methods for making and using such compositions, are generally described.

Abstract: A granular agrochemical composition is disclosed including a granular core material having a water soluble portion with a first coating layer applied on the surface of the core material and a second coating layer applied on the surface of the first coating layer. The first coating layer includes a wax composition having a biologically active ingredient incorporated therein and the second coating layer includes a polymeric composition. The granular agrochemical composition exhibits a controlled rate of release of the biologically active ingredient therefrom over a period greater than about 30 days from the date of initial exposure of the granular composition to moisture whereby essentially all of the biologically active ingredient incorporated in the wax material of the first coating layer is released from the granular composition before the water soluble portion of the granular core material is released from the granular composition.

Abstract: The invention relates to mixing devices, methods of operating mixing devices, and methods of blending a granular substrate with a coating material. These mixing devices and methods substantially prevent the agglomeration of solids and/or viscous liquids on rotational and/or static elements of the mixing device.

Abstract: The invention relates to methods and systems for coating substrates. In particular, the invention relates to methods and systems in which the coating and curing steps are performed in separate vessels. These methods and systems provide a more effectively controlled and efficient coating process.

Abstract: Improved, solid water-soluble fertilizer (WSF) compositions are presented which comprise at least one acid (optionally nutritive) and at least one basic fertilizer component. In one or more embodiments of the present invention, the WSF compositions demonstrate improved solubility of one or more nutrients or additives in solution, do not require additional dissolution aids or anti-caking agents, demonstrate fast dissolution times, produce precipitate free solutions, are readily compounded without intermediate wetting or drying steps, do not generate gas, and demonstrate improved stability under typical usage conditions. Finally, the WSF compositions may be used in improved processes for the creation of stock solutions, optionally with cold water, and/or delivery of nutrients to plants.
