Modeling of Water Flow and Solute Transport for Irrigation and Drainageltivated lands, about 0.34 × 10. ha (23%) is saline and another 0.56 × 10. ha (37%) is sodic. Fig. 1 (Szabolcs 1989) shows that saline and sodic soils cover about 10% of total arable land distributed over 100 countries. Although natural factors are the main causes of the occurrence of saline/sodic sPUT 发表于 2025-3-24 07:36:22
