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.

  • Soil sampling and testing is an essential part of making good fertiliser decisions. Fertilisers are a large cost to farming pastures in high rainfall areas.

  • 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 crop stres

  • Achieving good plant establishment after soil renovation can be challenging depending on the resulting soil surface conditions.

  • This page explains the terms and importance of soil structure (aggregate stability), cation exchange capacity, calcium to magnesium ratio and exchangeable sodium percentage.

  • We recommend using broad-based banks to intercept and divert surface water run-off in cropping areas where conventional banks would interrupt vehicle movement.

  • Dispersive soils are common in the agricultural area of Western Australia, where they occur mainly as duplex or gradational profiles.

  • Waterlogging is widespread in winter in the agricultural areas of Western Australia and is a major factor reducing crop yields, especially in wet years.

  • This glossary explains some of the terms used on this Western Australian website and in publications about climate, and land and water resources.

  • Leaky farm dams are a significant problem in some areas of Western Australia, and there are several ways of dealing with the problem. This page describes options for dealing with leaky dams.

  • The Department of Primary Industries and Regional Development (DPIRD) supports pastoral industries in Western Australia by supporting market development, providing information, and assessing change
