The application effects of natural zeolite at early stages of plant growth for two rangeland species (Ziziphose Spina christi and Acacia Salicina) under drought stresses

Zeolites are crystalline، hydrated aluminosilicates of alkali and alkaline earth metals. They are further characterized by large tunnels for a fluid to pass through، large ion exchange capacity، the ability to lose and gain water reversibly. The atomic structure and surface properties of zeolites make them suitable for many industrial and agricultural uses. In this study the application effects of natural zeolite was studied at the early stages of plant growth for two rangeland species (Ziziphose Spina christi and Acacia Salicina) under drought stresses. According to results، the number of reminded plants decreased during studied period for all treatments، but a significant different was observed between control pots (0% zeolite) and pots treated with zeolite (P < 0. 05) for stream size and number of reminded plants.
