GRANULAR FERTILIZERS AND METHODS OF MAKING SAME

Coated granules and methods of making the coated granules that prevent the coated granules from floating and/or drifting due to water current and wind are disclosed. The coated granules may include a core having a water-soluble compound, such as a fertilizer; a controlled release layer; a surface treatment including a surfactant to reduce water tension; and an optional coating disposed between the controlled release layer and the surface treatment layer that includes a gelling agent, such as a super absorbent polymer, that may help to anchor the coated granules to the surface of the soil and reduces the chance of relocation due to rolling.

GRANULES OF POLYHALITE AND UREA
20220259115 · 2022-08-18 ·

There is provided herein a fertilizer granule comprising Urea, Polyhalite and Ammonium Sulphate.

Controlled-release fertilizers

The present disclosure relates to a controlled-release fertilizer and, more particularly, to a controlled-release fertilizer comprising a photodegradable capsule including a binder resin containing a polyolefin and an ethylene vinyl acetate copolymer; and a photocatalytic composite in which a surfactant having an HLB value of 1 to 6 is bonded to the surface or inside of aggregates of inorganic fine particles, and a fertilizer contained in a space surrounded by the photodegradable capsule.

System for coatings for granular materials

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.

UREA GRANULATION PROCESS
20210316261 · 2021-10-14 · ·

A process of granulation of a urea melt, comprising: adding a first additive containing carboxymethyl starch to one or more first stage(s) of the granulation process, to form a carboxymethyl starch containing inner layer of urea granules, and adding a second additive containing calcium lignosulfonate to one or more second stage(s) of the granulation process, downstream said first stages, to form granules with a coating containing calcium lignosulfonate.

Coated granular fertilizers, methods of manufacture thereof, and uses thereof
