Abstract:
     A mixed compound fertilizer features use of clay minerals (askanite-type attapulgite and bentonite) as binder. Its granulating process includes the step of adding surfactant (0.001-2.7%) by spraying the aqueous solution of surfactant to the mixture of mixed compound fertilizer and clay minerals and/or immersing the clay minerals in said aqueous solution for modifying it. Its advantages are high productivity and low cost.
