Waterlogging

Waterlogging occurs when there is too much water in a plant’s root zone, which decreases the oxygen available to roots. Waterlogging can be a major constraint to plant growth and production and, under certain conditions, will cause plant death. This constraint may not be apparent until the whole soil profile is saturated and water appears on the surface. The department provides landholders with technical information and support on management options to recognise and reduce the impacts of waterlogging.

  • Shallow relief drains are effective at removing surface water from flooded land. Removing flood water reduces waterlogging and groundwater recharge and improves productivity of the soil.

  • Saline lands in Western Australia (WA) often suffer winter waterlogging, with the levels of salinity and depth to watertable varying markedly both spatially and between seasons.

  • Waterlogging is a common problem in the agricultural soils of south-west Western Australia in the wetter months of winter.

  • Waterlogging causes soil structure collapse in sodic soils, because the clay particles holding soil particles together disperse.

  • Relief wells can provide water resources and help reduce the severity and extent of waterlogging and salinity caused by leaky artesian systems.

  • Raised beds are a long-term option for waterlogged sites and increasing crop yield on target areas. We recommend that raised beds are part of a whole-farm water and salinity management program.

  • Members of the public can lodge a complaint about observed land management with the Commissioner of Soil and Land Conservation in Western Australia, and the Commissioner will then investigate the c
