Abstract:

To expand the application of attapulgite in the fertilizer field and enhance its added value, this review summarized the modification methods of attapulgite and its application research progress in fertilizers, to provide references for developing new fertilizers with low cost and high efficiency. The structural characteristics of attapulgite, common modification methods(thermal activation, acidification, surface organic modification, etc.), and their mechanisms were outlined. Emphasis was placed on analyzing the application effects, mechanisms, and existing challenges of modified attapulgite in various fertilizer systems, including slow-release fertilizers, controlled-release fertilizers and soil conditioners. Finally, future research directions for attapulgite-based functional fertilizers were prospected.

Key words: attapulgite, adsorption capacity, colloidal properties, slow/controlled release fertilizer, soil conditioners
