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.

  • Western Australian agriculture experiences variability in its winter growing season (May–October): late starts, early finishes and 'dry seasons' with rainfall low enough to cause serious plant and

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

  • Waterlogging causes significant reductions in plant growth in some years and some environments in the high rainfall (greater than 600mm annual rainfall) areas of South West Western Australia.

  • Claying involves adding and incorporating clay-rich subsoil into water repellent topsoil to overcome the repellence.

  • Irrigation design and management affects performance, yield and quality of crops.  Irrigation design determines the efficiency and effectiveness of water use, and therefore influences the profitabi

  • MySoil is a simple tool to identify soil types. Growers can use soil identification to improve soil management and reduce the impact of soil constraints.

  • The aim of carbon farming is to sequester more carbon and reduce greenhouse gas emissions, as part of Australia's response to climate change.

  • Soil organic carbon (SOC) is inherently low in Western Australian soils – limited by climate and soil type – with some potential to increase through management.

  • Soil organic matter influences nutrient supply and water-holding capacity in soil.

  • If you are deep-ripping, ploughing or spading to remove subsurface compaction or another constraint, it is a good idea to incorporate lime in the same operation.
