Yellow River sediment is the potential resource for saline–sodic soil reclamation. Experiments of one-dimensional columns were conducted to investigate upward and downward water transportation characteristics mixed with different addition (0, 10, 20 kg/m2 in top cm layer). The saturated hydraulic conductivity, ratio macroporosity, cumulative capillary adsorption infiltration rate all increased ...

Locally nuanced community-based shallow groundwater management interventions have proven important in saline and sodic monsoonal regions. A mixed methods approach characterizes achievement of regeneration the formerly degraded socio-ecological system Laporiya village semi-arid Salt Lake region Rajasthan state (India), with a focus on locally adapted chauka systems. Local people are key particip...

The study site is a typical, perched wetland in a saline, sulfidic discharge area in the eastern Mt Lofty Ranges near Adelaide, South Australia. The wetland is part of the 10% of strongly waterlogged landscape identified by GIS analysis of a larger 80 km area. Approximately 40% of this area was identified as being poorly drained, but only a small proportion, less than 10%, supports wetland vege...

Salt-affected soils, those on which plant growth is limited by an excess of salts, are of three types: (i) saline soils in which electrical conductivity is > 4 dSm 1; (ii) sodic soils in which the exchangeable sodium percentage (ESP) is > 15; and (iii) saline-sodic in which the electrical conductivity (EC) is > 4 dSm 1 and ESP is > 15. Salt-affected soils are most common in aridic moisture regi...
