Waterlogging causes clay to disperse in sodic soils, leading to soil structure collapse.
Permanent raised beds are a practical and economic means of managing some waterlogged sites in wetter areas of the Western Australian grainbelt.
Raised beds are a long-term option for waterlogged sites and increasing crop yield on target areas.
Waterlogging causes significant reductions in plant growth in some years and some environments in the high rainfall (greater than 600 mm annual rainfall) areas of South West Western Australia.
Waterlogging is a common problem in the agricultural soils of south-west Western Australia in the wetter months of winter.
Waterlogging in the higher rainfall areas (more than 450 mm annual rainfall) of south-west Western Australian crops and pastures is a common cause of reduced plant growth in winter, especially on d
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.
The use of no-till crop establishment practice is essential for farming raised beds. Cultivation is likely to degrade the bed and furrow construction.
Raised beds are a long-term option for preventing waterlogging and increasing crop yield on target areas.
