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.

  • 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

  • Waterlogging in some years and some environments in the high rainfall areas of south-west Western Australia can cause significant reductions in plant growth.

  • Waterlogging in the higher rainfall areas (more than 450mm) of south-west Western Australian crops and pastures is a common cause of reduced plant growth in winter, especially on duplex soils.

  • Permanent raised beds are a practical and economic means of managing some waterlogged sites in wetter areas of the Western Australian grainbelt.

  • Harvesting crops on raised beds differs from harvesting on normal seedbeds only in terms of the constraints imposed by tracking the harvesting equipment in furrows if so desired.

  • Drains in most waterlogging-susceptible cropped areas pay for themselves within a few years.

    Waterlogging occurs when there is insufficient oxygen in the soil pore space for plant roots to adequately respire.

  • Late-affected plants lodge and die prematurely

    Canola is more susceptible to waterlogging than cereals.
