GRDC Grains Research Update, online – Ameliorating sodicity – Central & Northern NSW & Qld

Past online event

Summary

The program from the February/March 2022 GRDC Grains Research Updates has moved online. While we and many participants lament not being able to run these events face to face, this is a fantastic opportunity for you to cherry pick  topics of interest to you not only from your area, but from the broader northern region.

Topics for this webinar:

• Ameliorating sodicity; what did we learn about ameliorating sodicity constraints with a range of treatments? ESP vs aggregate stability as an indicator of likely response to gypsum. (Chris Guppy, UNE & David Lester, DAF Qld)
• Satellite Sites – Ameliorating spatially variable soil constraints. What did growers try, what was done and how has it worked so far. (Stirling Roberton, USQ)
• The economics of ameliorating sodicity with gypsum and lime. (David McKenzie, Soil Management Designs)
• Ameliorating sodicity discussion – a consultant’s perspective. (Andrew Ceeney, Pinnacle Agriculture; Graeme Callaghan, Delta Agribusiness & David McKenzie, Soil Management Designs)

Update Papers

• Satellite sites – ameliorating spatially variable soil constraints. What did growers try, what was done and how has it worked so far?
• The economics of ameliorating sodicity with gypsum and lime
