عنوان مقاله [English]
In areas with high water table, due to evaporation from the soil surface, occurs accumulation of salts in the soil surface. Also the capillary rise of saline groundwater close to the surface, not only make evaporation from the soil surface and the loss of moisture but it entail soil salinization. Usually to prevent salinization of land, are used various methods to drain that these methods are envisage very the limitations of technical, economic and environmental existence. If you can prevent Another way of the capillary rise, can be expected to reduce the intensity of land salinization. So, the objective of this research was to evaluation the effect of the different levels of the superabsorbent polymer on reducing capillary rise from saline groundwater. This greenhouse experiment was carried out in four levels of superabsorbent polymer 0 (control), 100, 150, and 200 g added to a fine-textured soil in the cylindrical with diameter and height 30 cm and 3 replicates. The results showed positive effects of superabsorbent polymer on reducing capillary rise. Between different levels of superabsorbent polymer, application of 200 g of polymer is make to reduce of the capillary rise of saline groundwater and reduce the accumulation of salts in the surface layer of the soil, than in the control (treatment without polymer).
