研究了污水灌溉和地下水灌溉对耕地土壤磁化率和有机质含量的影响。结果表明，污水灌溉土壤有机质和磁化率值比地下水灌溉农业土壤分别提高了7.1%和13.5%。污水灌溉土壤和地下水灌溉土壤均含有大量超超准磁性颗粒，其高频相关磁化率（χfd >.6 %）较高。通过对土壤垂直剖面的调查，确定了人为污水灌溉和农用化学品的使用是土壤磁性增强的原因。磁化率参数与有机质含量呈显著相关（y = 0.0057x + 1.3439, R2= 0.09,p< 0.05）。这项工作表明，磁化率的测量可能为识别耕地土壤中的潜在污染提供快速的第一步。
This study assessed the effect on magnetic susceptibility and organic matter content of arable soil by irrigation with either treated sewage or groundwater. Results indicated that organic matter and magnetic susceptibility values in the soil irrigated with sewage were increased by 7.1 % and 13.5 %, respectively, compared to agricultural soil that irrigated with groundwater. Both the sewage and groundwater irrigated soils contained a significant fraction of ultrafine superpara magnetic grains, as indicated by high frequency dependent susceptibility (χfd> 6 %). The enhancement of soil magnetic properties was determined to be caused by anthropogenic sewage irrigation and agrochemical use by investigation of vertical soil profiles. Magnetic susceptibility parameters were shown to be significantly correlated with organic matter content (y = 0.0057x + 1.3439, R2= 0.09,p< 0.05). This work indicates that measurements of magnetic susceptibility may offer a rapid first step for identifying the potential pollution in arable soils.
