GRDC Grains Research Update, online – Nutrition – NNSW & Qld
Past online event
Date:
01 Mar 2022
Region: North
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
