    摘要: This invention relates to a process for the production of polyurea encapsulated fertilizer particles. These are produced by applying an isocyanate-reactive component which contains at least two amine groups to fertilizer particles to form amine coated particles, and applying a polyisocyanate component to the amine coated particles to form polyurea coated particles. These steps may optionally be repeated in successive order. The resultant polyurea encapsulated fertilizer particles contain from about 0.5 to 15% by weight of polyurea, based on the total weight of the encapsulated fertilizer particles. Instead of using an amine group containing isocyanate-reactive component, water can be applied first.
