Maintaining profitable farming systems with retained stubble

Crop residues, or stubble, play an integral role in soil health and nutrient cycling in broadacre cropping and, particularly in the Mallee, can also improve rainfall infiltration and moisture retention. However, while the benefits of stubble retention are widely recongnised, growers are … Continue reading

Break crops in retained stubble systems in the Wimmera and Mallee

Crop sequences are most profitable when break crops are included to solve agronomic problems (grass weeds, root disease, low soil N). Trial work has demonstrated that crop sequences involving a broadleaf break crop can be more profitable than continuous wheat. This … Continue reading

Guidelines for growers

The Victorian and Tasmanian stubble project will specifically examine 17 cropping system components that are directly impact, or interact with, crop residue in a stubble retained system. Guidelines on how growers can manage with each of these components while retaining stubble … Continue reading

Tracing crop nitrogen coming from the previous stubble

By Vadakattu Gupta, Therese McBeath (CSIRO) and Claire Browne (BCG) Key messages: Only 31 per cent of the applied urea nitrogen (N) was taken up by the wheat crop in 2014. This low fertiliser use efficiency may be partly related to the … Continue reading

Can we reduce nitrogen inputs for wheat sown onto high-input crop stubbles and still achieve high yields?

By Heather Cosgriff (SFS) Key messages: Soil nitrogen availability was very high prior to sowing, 321.6kg/ha available Incorporating poppy stubble led to high potentially mineralisable nitrogen levels There was no yield or protein response to additional urea applications Trojan generally … Continue reading

Nitrogen and sulphur timing in the Mallee

By Simon Craig (Agronomise, BCG consultant) Key messages: The application of nitrogen increased grain yield by 0.5t/ha, but there was no benefit from additional sulphur. At this site, money was better spent on nitrogen than on sulphur. Grain protein was very low (7-10% protein) which … Continue reading

Liquid versus granular nitrogen in bread and durum wheat

By Tim McClelland (BCG) and Rob Norton (IPNI) Key messages: In this trial, contrary to expectation, the durum wheat achieved an average yield only 0.1t/ha lower than bread wheat (Scout). During 2014, there was a price differential of between -$83 and $277 for durum (DR1) over … Continue reading
