Climate, land & water

Western Australia’s agriculture sector needs access to productive soil and water resources for growth and profit. However, the sector must compete with increasing resource demands from all sectors of the community, and the pressures of a changing climate. The Agriculture and Food division of the Department of Primary Industries and Regional Development supports agriculture by providing long-term management solutions, practical risk management strategies and tools to maintain and improve resource conditions, to meet the needs of industry and stakeholders. Agriculture and Food is also pioneering soil and water investigation of the state’s undeveloped areas to establish new irrigated agricultural industries.

  • Yellow, brown and red deep sands.

  • 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.

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

  • 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 preventing waterlogging and increasing crop yield on target areas.

  • 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 450mm) of south-west Western Australian crops and pastures is a common cause of reduced plant growth in winter, especially on duplex soils.

  • Frost risk occurs virtually every year across southern and eastern agricultural regions. Actual occurrence of frost is determined by location and landscape factors as well as climate.

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