Aqueous liquid formulations contain one or more anionic polymers, a high concentration of boron compounds, and a boron dispersant or solvent. The compositions are operable to maintain the boron content thereof in stable dispersion for at least 72 hours. The dispersant or solvent is selected from saturated aliphatic diols, glycols, hydroxyl-rich compounds, alpha-hydroxy acids, and mixtures thereof. Preferred polymers include dicarboxylic repeat units and optional sulfonate repeat units. The formulations have heretofore unattainable high boron contents, and are useful in agricultural contexts.

A process of manufacturing a coated fertilizer comprising: providing at least partially coated fertilizer granules having an at least partial coating comprising a polymer and a wax; and conditioning the at least partially coated fertilizer granules at a temperature of 40 to 130 C. for a time of 1 minute to 4 hours, to form a coating comprising interpenetrating domains comprising polymer domains and wax domains.

The invention relates to the field of controlled release fertilizer technology, and in particular to a special film-coated controlled release fertilizer for peanut in a high yield field, which comprises an outer layer, an intermediate layer and an inner layer, integrates the ingredients for disease and pest control, chemical control, growth promotion and premature senescence prevention, controls the release period, improves the fertilization efficiency without the need of top application throughout the growth period, saves labor cost, and has positive effects on improving peanut yield and quality.

Novel granular fertilizers and methods of making those fertilizers are provided. The method utilized involves recycling streams, including one that provides water having dissolved solids therein, with that water being used during the mixing and granulation process. This method results in a low-moisture, hard, substantially spherical granule, which can include any number of macronutrients and/or micronutrients. Advantageously, the granular fertilizer can be applied to the soil around plants to supply those plants with the necessary nutrients.

Disclosed is a functionalized particle having at its core a porous particle that acts as a structured support element. This porous particle is surrounded by a protective sealant layer encasing the porous particle. The particle includes a plurality of pores holding a first beneficial agricultural component. The functionalized particle can also include a plurality of functionalized molecules embedded in the sealant layer. The functionalized molecules comprise a base material, comprising an active agricultural component or an inactive material, and an active second beneficial agricultural component. The functionalized molecules can all contain the same base material and the same active second beneficial agricultural component or a mixture of different base materials and a mixture of second beneficial agricultural components. The first and second beneficial agricultural components can either be single components or a mixture of components and may be the same or different from each other.

A coating is applied in one or more layers on a granular material, such as a granular fertilizer material or the like. The coating may include a diisocyanate in either pure form or partially polymerized form, a polyol or polyol mix, and optionally a wax. The polyol or polyol mix may be, for example, a polyester polyol, a polyether polyol, or combinations thereof. In some examples, the polyol or polyol mix may be an aliphatic glycerine initiated polyether polyol, an aliphatic amine initiated trifunctional polyol, castor oil or castor oil derivative, or ethylene diamine that has been propoxylated or ethoxylated, and combinations thereof. The coating is reacted on the granular material.

The present disclosure generally relates to layer-wise agglomerated controlled release granular urea composition and methods of making and using the layer-wise agglomerated controlled release granular urea composition. In a particular composition, the water-soluble plant nutrient comprises urea, the binding material for the core comprises corn starch, the hydrogel for the coating layer comprises corn starch hydrogel, the core has a thickness of 2.5-3.5 mm and a closed porosity of 0.05-3%, and the coating layer has a thickness of 1.35-1.5 mm and a closed porosity of 0.1-5%.

Methods, systems, and apparatuses for coating a fertilizer material by contacting the material with a coating material and a solvent are disclosed herein. The coated material can be obtained by mechanically agitating the fertilizer material while contacting the fertilizer material with a coating material and a solvent. The coating material can be sprayed onto the fertilizer material during mechanical agitation. The coating process and apparatus can use a paddle mixer and can be configured to handle organic solvents used to carry the coating material.
