摘要

Soil erosion and dust storms are the main causes of air pollution in regions where there are dust emitting centers and in their adjacent locations. In recent years, various methods have been considered for stabilizing soil surface against wind erosion. In this study, the effects of two stabilizers (anionic polyacrylamide polymer and vegetable-based mulch) for reducing soil loss at four levels of concentration (0, 15%, 30%, and 60%) on three kinds of soils in western Khuzestan, Iran have been studied. The study was conducted in natural and laboratory-based conditions in four, time intervals (0, 3, 6, and 12 months). Moreover, the study covered the persistence and influence of stabilizers on soil chemical properties. The results showed that wind erosion in no treatment was between of 16.36 kg/m(2)/hand 26.73 kg/m(2)/ h. The statistical results showed that there was a significant difference between the no treatment and soils treated with stabilizers. The polymer reduced soil loss by more than 90%. Mulch efficiency reduced in natural conditions after 6 months; however, there were no changes in laboratory conditions. There was no significant difference between polymer efficiency in the laboratory and natural conditions and the polymer was resistant in natural and laboratory conditions. Polymer increased EC, pH, and SAR in the soil after 1 year. Mulch decreased pH and SAR but did not change EC.
