Salinity and sodicity

3 steps

Capillary rise from shallow groundwater and salt accumulation

2 steps

Leaching requirement LR = ECiw / (5 ECe - ECiw): irrigating with 1 dS/m water on a crop tolerating ECe 4 dS/m needs about 5% extra water
Secondary salinisation: rising water tables after clearing or irrigation bring salts into the root zone; drainage and lowering the table restore the soil

Cation exchange, pH and soil solution chemistry

1 step
