Study on the main exchangeable cations dynamic change in the sulfuric acid modified zeolite

in recent years, natural zeolite has been widely applied in agriculture.The experiment mainly activation assay on natural zeolite by sulfuric acid, and then through monitoring exchangeable cations (K+, Ca2+, Mg2+, Na+)and cation exchange capacity in zeolite of the dynamic changes within a year, these cations have an important impact on plant growth. The dynamic changes in sulfuric acid modified zeolite can supply theoretical basis for that as crops of mineral fertilizer.
