ROLLESTON GRDC Grains Research Update - Thursday 18 November 2021

The latest grains research to improve profit will be at the Rolleston GRDC Grains Research Update. Discuss how to make practical use of the latest information relevant for the region.

Catchment water quality and the Great Barrier Reef. What sediment loads, nutrients and chemicals are in CQ waterways?  Which pose the greatest threat and why? How do we compare with other areas?  How are ecotoxicology risks measured and reported?
Kevin McCosker (DAF Qld)

Nitrogen strategies with P and K, application timing, surface spreading and N losses.
David Lester (DAF Qld)

Update on Deep P research in CQ.
Doug Sands (DAF Qld)

Wheat time of sowing and optimising flowering dates and new long coleoptile wheats and sowing depth.
Darren Aisthorpe (DAF Qld)

Optical sprayers - management optimisation and field experience with their use on robotic platforms.
Jeremy Jones (Dalby Rural)

  • Regulatory compliance: 2,4-D label, product registrations
  • Nozzle type, capacity, fan angle, and number of nozzles firing (for systemic and contact herbicides)
  • Efficacy, weed size, speed, coverage, wind, weed detection
  • Herbicide mixing, compatibility, agitation.

High competition sorghum – how do narrow rows and high populations affect crop productivity, water and nutrient use and legacies in the farming system.
Lindsay Bell (CSIRO)

Farming systems - Key findings on system profit, nitrogen and water use efficiencies, crop legacy effects, crop competition (row spacings and populations), crop diversity, use of manure and N timing from 7 seasons of research.
Lindsay Bell (CSIRO) & Ellie Parkinson (DAF Qld)

Tillage and surface cover impacts on fallow efficiency, infiltration, evaporation, erosion and run-off in CQ.
David Freebairn

Managing the farming system to maximise water capture and minimise soil erosion and runoff losses.
