Top processes

Capillary rise from shallow groundwater and salt accumulation

5 steps

Soil evaporation stages and capillary rise from shallow groundwater

4 steps

Start: Soil evaporation stages and capillary rise from shallow groundwater
End: Soil evaporation stages and capillary rise from shallow groundwater
Capillary rise from a water table: fringe height is about 0.15 cm2 divided by the pore radius, from roughly 0.1-0.3 m in coarse sand to over 1.5 m in silt and clay
and 1 more in this process

Water infiltration, retention and movement

3 steps

Nitrate leaching from the root zone to groundwater and coastal waters

3 steps

Nutrient availability and leaching

2 steps

Nitrogen cycling

1 step

Nitrate leaches below the root zone into groundwater and streams

Show 6 more processes

Soil sulfur cycling

1 step

Sulfate leaches with calcium, magnesium and potassium into drainage water

Base cation cycling (calcium, magnesium, potassium, sodium)

1 step

Mobile anions (nitrate, sulfate, bicarbonate) carry cations out in drainage

Preferential flow and macropore bypass

1 step

Fast transport of Nitrate, pesticides and pathogens to drains and groundwater

Salinity and sodicity

1 step

Shallow water table rises by capillary action; salt is left at the surface

Pedogenesis and soil horizon development

1 step

Gleying under waterlogging reduces iron and leaves grey mottled horizons

Soil-plant-water coupling and drought response

1 step

Deep roots reach moist subsoil and groundwater
