retained stubble

Catalogue: Ground Cover
Agriculture remains a target in the world's push to reduce greenhouse gas emissions, but local studies show the industry has ready-to-hand options that should not compromise production or profitability.. In research looking at ways to reduce cropping's contribution to greenhouse gas emissions, common management practices such as no-till and stubble retention have emerged as ready-made tools... Results suggest that greenhouse gas reductions could come from efforts to reduce nitrous oxide emissions by the following changes in management: applying up to 25 per cent less nitrogen fertiliser; using short-term, green manure legume crops in place of fallows; regular applications of beef or chicken feedlot manure (if available); and nitrogen fertiliser applied at sowing instead of at four to six weeks prior to sowing...

For many growers, particularly in higher rainfall and irrigated areas, stubble can cause significant management issues that can affect their profitability... In the situations, many growers are forced to remove the stubble, principally through burning... Advances in machinery technology has meant there are alternative methods or practices that growers may employ to successfully retain stubble whilst minimising the issues that come with retaining stubbles...

14 BWD00024: Maintaining profitable farming systems with retained stubble in Victoria and Tasmania .................................... The over-arching aim of the project is to improve yield and water-use-efficiency of irrigated wheat production across the Northern Region by developing improved agronomic practices to reduce the incidence of lodging and increase the yield potential of irrigated wheat... Overall, the project will deliver a comprehensive research, communication and extension program that will ensure more effective management of water repellent agricultural soils in WA whilst building capacity for future soils research and development in Western Australia...

The stubble management decisions each of these growers made in 2010-2011 were unique to the individual and were influenced by the combination of experiences, cropping systems, agronomic and logistic challenges, and commitment to full stubble retention...

Over the last decade there has been a large shift by Mallee farmers to adopt stubble retention systems with no-till in their farming systems... Key factors include: Growers that have been utilising stubble retention and no-till farming systems for many years are facing production and profitability constraints and have general concerns that their farming system as a whole is not performing as well as it should be, relative to more traditional farming systems involving low groundcover and higher erosion risks... Project outcomes will be achieved by employing a range of project activities that combine targeted local extension to address gaps in motivation, attitude and ability with on-farm field trial activities designed in collaboration with local farmers and advisors in mallee (including Victoria, NSW and SA) to fill gaps in local knowledge and understanding...
