Zusammenfassung:	The present invention relates to a controlled-release coated fertilizer and a manufacturing method therefor and, specifically, to a controlled-release coated fertilizer and a manufacturing method therefor, the fertilizer comprising thereon a chemical resin coating, followed by a sodium bentonite coating. In the controlled-release coated fertilizer of the present invention, a natural clay material is added to the coating surface of the fertilizer at an optimal ratio, which can cause cracks and rupture of the coating due to a difference in swelling degree between the chemical resin and the natural clay material, thus enabling the appropriate elution of fertilizer ingredients. Accordingly, the controlled-release coated fertilizer and the manufacturing method therefor of the present invention can be advantageously used in the fertilizer industry. La présente invention concerne un engrais enrobé à libération contrôlée et son procédé de fabrication et, plus particulièrement, un engrais enrobé à libération contrôlée et son procédé de fabrication, l'engrais comprenant à sa surface un enrobage à base d'une résine chimique, puis un enrobage à base de bentonite sodique. Dans l'engrais enrobé à libération contrôlée de la présente invention, un matériau à base d'argile naturelle est ajouté à la surface d'enrobage de l'engrais selon une proportion optimale, ce qui peut provoquer des fissures et une rupture de l'enrobage en raison d'une différence de degré de gonflement entre la résine chimique et le matériau à base d'argile naturelle, permettant ainsi une bonne élution des ingrédients de l'engrais. En conséquence, l'engrais enrobé à libération contrôlée et son procédé de fabrication selon la présente invention peuvent être avantageusement utilisés dans l'industrie des engrais. 본 발명은 완효성 피복비료 및 이의 제조방법에 관한 것으로서, 구체적으로, 비료 상에 화학수지 코팅 및 이후 소듐 벤토나이트 코팅을 포함하는, 완효성 피복비료 및 이의 제조방법에 관한 것이다. 본 발명의 완효성 피복비료는 비료의 코팅면에 천연점토 물질을 최적의 비율로 첨가함으로써 화학수지와 천연점토 물질의 팽윤도 차이에 의해 코팅의 균열 및 파열을 야기시킬 수 있고, 이에 따라, 비료의 성분을 적절하게 용출시킬 수 있는 작용효과를 나타낼 수 있다. 이에 따라, 본 발명의 완효성 피복비료 및 이의 제조방법은 비료 산업에서 유용하게 이용될 수 있다.
