Abstract

생분해성수지(로진, 왁스, Polycaprolactone 또는 각각의 혼합물) 등을 매트릭스수지로 사용하여 압출기내에서 용융 혼합한 후 압출시켜서 비료성분을 피복시킴으로 비료성분의 수중용출속도를 현저히 저하시킨 경제성 높은 매트릭스형 완효성 비료 및 그의 제조방법에 관한 것이다.Biodegradable resin (rosin, wax, polycaprolactone or mixtures thereof) is used as the matrix resin, melt mixed in the extruder and extruded to coat the fertilizer components, thereby significantly reducing the dissolution rate of the fertilizer components in water. It relates to a fertilizer and a method for producing the same.
