| Abstract: | Zeolites have natural framework of alumino-silicate minerals with high cation-exchange capacity. In this paper, the physical and chemical properties and the effects of natural zeolites on soil chemical and physical characteristics were reviewed. Zeolites application can increase fertilizer use efficiency and nutrient preserving capability of soil. The adsorption feature of zeolites can strengthen soil crumb structure, increase the cation exchange capacity and base saturation percentage. |
