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.


  • Mating ewes early (at eight to 10 months of age) could enable farmers to reduce whole farm methane production because this practice would also reduce the number of adult ewes.

  • Nitrates from nitrogen fertiliser are readily leached from all soils, but leaching is particularly rapid on sands.

  • Good fertiliser management is about balancing costs and returns so that the balance comes out in your favour. Failing to implement best practice nutrition programs can lead to poor returns.

  • Irrigation systems that are not designed, maintained or used efficiently can cost growers in lost productivity, excess water use, unused fertiliser loss, and excessive energy bills.

  • Scattered germination due to insufficient soil moisture

    Early drought may affect germination and early growth. Water stressed seedlings are more severely affected by other constraints and may have induced nutrient deficiencies.

  • Summer crops can be grown for various reasons including replacing a ‘missed’ cereal crop, control herbicide resistant weeds, filling a summer feed gap for livestock or for watertable control.
