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).

WebSaline- sodic soils have high ESP (> 15%) and high salinity (EC > 4 dS m −1) (table 1). These soils typically have better soil physical condition than non-saline sodic soils because their … WebJan 5, 2024 · In this scheme, SAR and EC are presented as they relate to the classification between a saline soil (EC >4, SAR< 13), a sodic soil (EC<4, SAR> 13), and a saline-sodic soil (EC>4, SAR>13). As shown, exchangeable sodium percentage (ESP) can be substituted at 15% as a threshold value [2]. susan ghazizadeh

Correspondingly, when the soil salinity (electrolyte concentration) was maintained below a critical threshold level that is soil dependent, the hydraulic conductivity and permeability of study soils decreased as the ESP was increased, i.e., barcelona open 2022 wikipedia
