Abstract
The present disclosure provides a method for treating a solid fertilizer. The method comprises contacting the solid fertilizer with an amount of a liquid composition effective for reducing clumping in the fertilizer caused by absorption of water. The liquid composition may comprise one or more organic solvents and/or petroleum distillates. The organic solvents may be selected from the group consisting of glycol, dialkylcarbonate, C1-C4 alcohol, vegetable oil, esters of hydroxyacids, heterocyclic alcohols, cyclic esters of carbonic acid, and esters of dicarboxyacids.
Claims16
A method for treating a solid fertilizer to reduce clumping, the method comprising:
- contacting the solid fertilizer with an amount of a liquid composition effective for reducing moisture-induced clumping in the solid fertilizer,
- the liquid composition comprising one or more organic solvents and/or petroleum distillates;
- wherein the liquid composition comprises propylene glycol and ethyl lactate;
- the solid fertilizer is mixed with the liquid composition by stirring, blending, shaking or rotating in a mixing device;
- the liquid composition and solid fertilizer are present in amounts of about 0.065 L/kg to about 1 L/kg;
- and
- the mixing occurs for at least a plurality of minutes.
A method for treating a solid fertilizer, the method comprising:
- contacting the solid fertilizer with an amount of a liquid composition effective for reducing moisture-induced clumping in the solid fertilizer,
- the liquid composition comprising one or more organic solvents and/or petroleum distillates;
- wherein the liquid composition comprises:
- 5-30% (w/w, of the total composition) C1-C4 alcohol;
- 20-50% (w/w, of the total composition) vegetable oil;
- 50-75% (w/w, of the total composition) surfactant;
- and
- 0-5% (w/w, of the total composition) dye.
A fertilizer composition comprising:
- 99-99.8% (w/w, of the total composition) solid fertilizer comprising one or more of urea, ammonium sulfate, potassium sulfate, phosphorite, diammonium phosphate, potassium oxide, langbeinite, or lime;
- 0.18-0.99% (w/w, of the total composition) propylene glycol;
- and
- 0.01-0.1% (w/w, of the total composition) ethyl lactate.
