| 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. |
