CWFS are conducting trials at its regional sites that - investigate the impact of different stubble treatments imposed towards the end of the fallow have on nitrogen response (applied as urea) in wheat yield and quality - evaluate the widely used advisor/farmer benchmark of 20 kg actual N required per tonne of expected yield.

Work conducted by Clive Kirkby (CSIRO) has investigated the feasibility of increasing soil carbon levels with the use of balanced amounts of nutrients and incorporation of stubble.

The overall aim of the project was to raise awareness of farmers about how they can reduce green house gas emissions, sequester soil carbon and make improvements in farm productivity.

To compare no till farming techniques against conventional farming methods over 5 different cropping rotations: No-till • all weed control by herbicides or narrow windrow burning • sown with NDF single disc seeder • stubble retained where possible Conventional • weed control both by herbicides and cultivation • sown with NDF single disc seeder • stubble incorporated.

The aim of this work is to understand the impact of stubble retention on in-canopy temperatures and associated risk of frost in cropping environments with high yields and high stubble loads.

The aim of this work was to better understand the impact of stubble management on in-canopy temperatures and the associated risk of frost in cropping environments with high yields and high stubble loads.

• To investigate the impact of different stubble treatments imposed towards the end of the fallow have on nitrogen response (applied as urea) in wheat yield and quality.
• To evaluate any interaction between pre-sowing stubble treatment and topdressing timing.

To investigate the impact of different stubble treatments (burning, cultivation or standing stubble) imposed towards the end of the fallow have on the yield of wheat and barley, and evaluate any cultivar responses within crop species to the impact of the different stubble treatments.
