WebSaline soils have traditionally been classified as those in which the ECe of the saturation extract is >4 dS m −1 and ESP <15%. Some scientists have recommended that the EC e limit for saline soils be lowered to 2 dS m −1 as many crops, particularly fruits and ornamentals, can be harmed by salinity in the range of 2–4 dS m −1. WebJun 10, 2024 · Saline-sodic soils account for more than 10–12% of the world’s irrigated land (Wang et al. 2024).Saline-sodic soils are rich in both soluble salts (EC e > 4 dS m −1) and exchangeable Na + (ESP > 15%) (Oad et al. 2002).However, the leaching of soluble salts usually indicates Na + as a great problem that causes a pH rise to > 8.5 (Sparks 2003).
