A particle is provided for delivery of humics, and biochar that is water-dispersible into constituent granules. The resulting particles are amenable to broadcast application, for example via rotary or drop spreader. As a result, a dust-free particle is formed that simultaneously addresses the prior art problems of the friable nature of humics and the sooty dusting property of biochar to facilitate ease of handling, broadcast field spreading, and gain the synergistic effects of dosing soil with both humics and biochar. The particle provides improved storage capabilities for materials improving the quality of the delivered material and decreasing negative storage consequences such as odor emanation or degradation. The resulting particles upon dispersion have a pH of between 3.3 and 8.1.

A method of reducing dust formation and/or caking in fertilizer or other particulates. The method comprises coating the fertilizer or other particulate in a coating comprising vacuum tower asphalt extender (VTAE). The VTAE may be a non-distilled fraction of vacuum distillation of used automotive and/or industrial oil. The VTAE may not be asphalt or bitumen, although the coating may further comprise bitumen.

A particulate fertilizer coating composition or a coated fertilizer containing a solid acidic particulate material and a solid basic particulate material. The coating composition and coated fertilizer are each stable, chemical compatible with other fertilizers, and/or are abrasion resistant.

The present disclosure is related to a conditioning agent for reducing water absorption and dust formation of a particulate fertilizer, comprising 50 to 60 weight % of wax, 30 to 40 weight % of oil, 1 to 15 weight % of a resin being oil-soluble and miscible with wax and oil, and optionally 0.01 to 2.0 weight % of a viscoelastic elastomer which is soluble in oil. The conditioning agent may be applied to a particulate substrate, in particular a fertilizer particulate substrate, to reduce the moisture uptake and the dust formation of the substrate, in particular wherein the substrate is blended with other particulate compositions.

A coated fertilizer comprises a fertilizer granule; and a coating disposed on a surface of the fertilizer granule, wherein the coating comprises a poly(lactic acid); a second polymer comprising a poly(butylene succinate), a cellulose triacetate, or a combination comprising at least one of the foregoing; and a sealant. Methods of making the coated fertilizer are also disclosed.

A method for producing potassium chloride granulates from a crystalline potassium chloride raw material. The potassium chloride raw material is treated, prior to granulation, with at least one alkali metal carbonate and at least one phosphate additive selected from alkali metal monophosphates, alkali metal pyrophosphates, linear alkali metal polyphosphates and mixtures thereof, in the presence of water.
