Abstract 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/m2/hand 26.73 kg/m2/ 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.

土壤稳定剂抗土壤流失的效果及其对土壤化学性质的影响研究

摘要 土壤侵蚀和沙尘暴是造成沙尘排放中心及其邻近地区空气污染的主要原因。近年来,已经考虑了各种方法来稳定土壤表面以防止风蚀。在本研究中,两种稳定剂(阴离子聚丙烯酰胺聚合物和植物基覆盖物)在四个浓度水平(0、15%、30% 和 60%)下对西胡齐斯坦三种土壤的减少土壤流失的影响,伊朗进行了研究。该研究是在自然条件和实验室条件下以四个时间间隔(0、3、6 和 12 个月)进行的。此外,该研究涵盖了稳定剂对土壤化学性质的持久性和影响。结果表明,未处理的风蚀在16.36 kg/m2/手26.73 kg/m2/h之间。统计结果表明,未处理与稳定剂处理的土壤之间存在显着差异。该聚合物使土壤流失减少了 90% 以上。6个月后自然条件下地膜效率降低;然而,实验室条件没有变化。聚合物在实验室和自然条件下的效率没有显着差异,聚合物在自然和实验室条件下都具有抗性。1 年后,聚合物增加了土壤中的 EC、pH 和 SAR。覆盖物降低了 pH 值和 SAR,但没有改变 EC。聚合物在实验室和自然条件下的效率没有显着差异,聚合物在自然和实验室条件下都具有抗性。1 年后,聚合物增加了土壤中的 EC、pH 和 SAR。覆盖物降低了 pH 值和 SAR,但没有改变 EC。聚合物在实验室和自然条件下的效率没有显着差异,聚合物在自然和实验室条件下都具有抗性。1 年后,聚合物增加了土壤中的 EC、pH 和 SAR。覆盖物降低了 pH 值和 SAR,但没有改变 EC。
