Soil constraints are reducing grain grower profitability in Western Australia. Soil compaction, low pH and water repellence are estimated to cost the state’s grains industry a billion dollars annually in lost productivity.That is why the GRDC invested in a multi-organisation 5 year R&D program called the Soil Constraints West Initiative. Now in its final year and with up to $33 million invested, changes are happening on farm.Chris Gazey from the Department of Primary Industries and Regional Development is Soils and Nutrition portfolio manager with the Department and oversees the Soil Constraints West projects.The 'ranking options for soil amendments' (ROSA) tool provides a cost-effectiveness ranking of soil amendment options to address one or more soil constraints within a farm business.Check out the ROSA decision support tool: https://www.agric.wa.gov.au/climate-land-water/soils/managing-soilsYouTube playlist, Soil Constraints: https://www.youtube.com/playlist?list=PL2PndQdkNRHHe0RZUASSU6fpCtkpHK6vLFurther information:Chris Gazey0429107976chris.gazey@dpird.wa.gov.auhttps://www.agric.wa.gov.au/climate-land-water/soils/managing-soils
