Abstract
A coated granular inorganic substance and a method for producing the coated substance are provided. The coated granular inorganic substance includes inorganic particles having outer surfaces at least partially coated with an organic layer which includes a phosphorus-containing, amphiphilic component. A coating composition which includes a phosphorus-containing, amphiphilic component and a fertilizer spreader containing fertilizer particles having outer surfaces substantially coated with an organic layer which includes the phosphorus-containing, amphiphilic component are also provided.
Claims26
A coated granular substance comprising:
- inorganic particles having outer surfaces at least partially coated with an organic layer;
- wherein the organic layer includes (i) a phosphorus-containing, amphiphilic component and (ii) lipophilic diluent including fatty acid lower alkyl ester, mineral oil or a mixture thereof;
- and at least about 90% of the inorganic particles have a particle size of 1 mm to about 6 mm.
A method of producing inorganic particles at least partially coated with an organic layer, said method including:
- applying a coating composition to the inorganic particles;
- wherein the coating composition includes (i) a phosphorus-containing amphiphilic component and (ii) lipophilic diluent including fatty acid lower alkyl ester, mineral oil or a mixture thereof;
- and at least about 90% of the inorganic particles have a particle size of 1 mm to about 6 mm.
A method of reducing dust associated with fertilizer particles, said method including:
- applying a dust reduction composition to the fertilizer particles;
- wherein the dust reduction composition includes (i) a phosphorus-containing amphiphilic component and (ii) lipophilic diluent including fatty acid lower alkyl ester, mineral oil or a mixture thereof;
- and at least about 90% of the inorganic particles have a particle size of 1 mm to about 6 mm.
A fertilizer spreader containing fertilizer particles, said fertilizer particles having outer surfaces at least partially coated with an organic layer;
- wherein the organic layer includes (i) a phosphorus-containing, amphiphilic component and (ii) lipophilic diluent including fatty acid lower alkyl ester, mineral oil or a mixture thereof;
- and at least about 90% of the inorganic particles have a particle size of 1 mm to about 6 mm.
A fertilizer composition formed by a process comprising applying a coating composition to fertilizer particles, wherein the coating composition includes (i) a phosphorus-containing amphiphilic component and (ii) lipophilic diluent including fatty acid lower alkyl ester, mineral oil or a mixture thereof;
- and at least about 90% of the inorganic particles have a particle size of 1 mm to about 6 mm.
