GRDC Grains Research Update, online – Nutrition – NNSW & Qld

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:

• Deep P and K - a call to action!  Critical soil indicators, costs, benefits and timing of deep P & K (outcomes from 8 years of research). (David Lester & Doug Sands, DAF Qld)
• P dynamics in vertosols - what factors influence how long deep P lasts and the impact of application method and subsequent tillage on plant response. (Nelly Raymond, UQ)
• Root research:  What do wheat and sorghum roots do when water is in one part of the profile and P is in another? Root angle and why does it matter? (Frederik van der Bom, UQ)
• Nitrogen release dynamics of Enhanced Efficiency Fertilisers (EEFs): placement, soil factors, plant uptake. (Cristina Martinez & Chelsea Janke, UQ)

Update Papers

• Nitrogen release dynamics of enhanced efficiency fertilisers (EEFs): placement, soil factors and plant uptake
• Ameliorating sodicity; what did we learn about ameliorating sodicity constraints with a range of treatments? Yield responses to ripping, gypsum and OM placement in constrained soils
• Root research: What do wheat and sorghum roots do when water is in one part of the profile and phosphorus is in another? Root angle and why does it matter?
• P dynamics in vertosols – which soil properties affect declines in P availability over time? Are there differences between MAP and DAP?
• Deep P and K - Outcomes from 8+ years of research: the good, the bad and the ugly
