Abstract
A fertilizer granule having a coating on at least of portion of a surface of the granule. The coating is made of one or more complexing agents and a coating agent of one or more of a fatty acid, fatty acid ester, organic oil mineral oil or combinations thereof. The coating may optionally include a surfactant and micronutrients. The coated fertilizer granules demonstrates a noted improvement in the utilization of the nutrients of plants and crops.
Claims21
A composition comprising a fertilizer granule having a surface, a coating on a least of portion of the surface of the granule, wherein the coating comprises, (i) one or more complexing agents, wherein the one or more complexing agents are capable of dissolution through contact with water, and (ii) a coating agent.
A method comprising, coating a plurality of fertilizer granules with (i) one or more complexing agents, wherein the one or more complexing agents are capable of dissolution through contact with water, (ii) a coating agent, and (iii) optionally one or more micronutrients, and (iv) optionally a surfactant.
A method for forming a coating of micronutrients on fertilizer granules, the method comprising:
- (a) providing (i) a plurality of fertilizer granules, (ii) a dry component having at least one complexing agent, wherein the at least one complexing agent is capable of dissolution through contact with water, and (iii) a liquid component having a coating agent,
- (b) blending the fertilizer granules with the dry component and the liquid component to form a coating containing the at least one complexing agent and the coating agent on at least a portion of a surface of each of the plurality of fertilizer granules.
