Take home message
• Deep ripping compacted soils appears to have short term benefits but soil collapses shortly afterwards sometimes to a worse state than the original condition
• While tillage and nutrition treatments have stood out in historic wet seasons, the recent dry season indicates gypsum with ripping has improved water capture and yields
• Return on investment from treatments has occurred in shorter timeframes than expected
• Results from on-farm research trials indicate positive responses are soil dependent and the importance of finding the right solution for your soil.
