Title

(EN) CONTROLLED RELEASE FERTILIZER AND METHOD FOR PRODUCTION THEREOF

(JA) 徐放性肥料およびその生産方法

Abstract

(EN)

PROBLEM TO BE SOLVED: To provide a controlled release fertilizer having a release rate profile in which the excessive supply of a nutrients does not occur, and to provide a method for production thereof.

SOLUTION: A controlled release fertilizer material comprises a particulate plant nutrient surrounded by a coating which is the reaction product of a mixture comprising: a polyol, an isocyanate and an organic wax. The plant nutrient contains at least one selected from the group consisting of nitrogen, phosphorus, potassium, sulfur and mixtures thereof. An isocyanate is selected from the group consisting of diphenylmethane diisocyanate, toluene diisocyanate, aliphatic isocyanate, their derivatives, polymers, and their mixture.
