Abstract
A method of forming a pelletized fertilizer includes combining a fertilizer material with an organic binder to form a wet mixture, and drying the wet mixture to form particles comprising the fertilizer material and the organic binder dispersed therein. The fertilizer material includes solid particles of langbeinite, and the organic binder includes at least one cellulose polymer in a solid phase or a liquid gel phase. The dried particles are coated with mineral oil to form coated particles. A pelletized fertilizer includes pellets comprising solid particles of langbeinite (and optionally, other fertilizer materials) interspersed with at least one cellulose polymer. A mineral oil coating is over the pellets.
