Through the Australian Government's climate change initiative, Australia's Farming Future - Climate Change Research Program (CCRP), the Department of Agriculture, Fisheries and Forestry (DAFF) and the Grains Research and Development Corporation (GRDC) have commenced a demonstration program called the National Adaptation and Mitigation Initiative (NAMI)... GRDC is in partnership with Birchip Cropping Group (BCG), the Department of Employment Economic Development and Innovation (DEEDI), the Department of Primary Industries Victoria (DPI Vic) and the Department of Agriculture and Food Western Australia (DAFWA) in the delivery of the initiative... GRDC Managing Director Peter Reading says the initiative will play an important role in equipping primary producers with tools to adapt and adjust to the impact of climate change and to manage their emissions...

" Measurement of paddock-based greenhouse gas emissions from wheat production to improve life cycle assessment of wheat-products DAW00103 Start Date: 31/12/2003.. 2) The emission factor (EF) for nitrous oxide could be reduced from the Department of Climate Change (DCC) standard of 0.3% to a lower figure measured in these experiments eg. 0.06%... As part of the project, greenhouse gas emissions were measured for a rain-fed wheat crop and for lupin and canola crops for comparison...

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...

" Over the Fence: Cut fertiliser costs and reduce greenhouse emissions - Apr 2011 09 August 2012 NEW research is showing the way for farmers to cut both their nitrogen fertiliser bills and greenhouse gas emissions from their farm... The research into nitrous oxide emissions on grain growing properties hopes to show that more efficient use of nitrogen on-farm not only saves the business money, but also limits the amount of greenhouse gas released from the soil during the growing season...

In one project partnered by BCG (formerly the Birchip Cropping Group), 10 farming systems groups across Victoria, NSW, South Australia, Tasmania, Western Australia and Queensland are trialling practical measures aimed at minimising the impact of climate change on farm viability... The specific objectives of the NAMI initiative are to: directly involve farmers and advisers in designing on-ground demonstrations of locally relevant adaptations to climate change to maintain or improve farm viability; assist rapid dissemination of information about adapting to and mitigating climate change; assess the greenhouse gas emission implications of different farming practices; demonstrate practices that could reduce net greenhouse gas emissions from nitrous oxide and methane as well as increase soil carbon sequestration; and increase awareness and knowledge in the grains industry of the viability of greenhouse gas mitigation strategies and demonstrate how to put them into practice... GRDC managing director Peter Reading says the initiative will help equip primary producers with the tools to adapt and adjust to the impact of climate change and manage greenhouse gas emissions - two issues that have been identified as key 'drivers for change' in the industry to 2012 and beyond...

University of Western Australia researchers are investigating approaches for decreasing greenhouse gas emissions from cropping systems By Louise Barton Key points.. Although incorporating grain-legumes, such as lupins, into cereal rotations is known to decrease the amount of synthetic nitrogen applied to the following cereal crop, it is not known if grain-legume production further enhances soil N2O emissions (and negating the benefit of lower CO2 emissions from urea hydrolysis)... Researchers are measuring soil N2O emissions from lupin-wheat rotations using soil chambers...

" Fertiliser Management Strategies for Decreasing On-Farm Greenhouse Gas Emissions.. In south-western Australia, previous research demonstrated that applying N fertiliser as urea contributed ca. 80% to total on-farm emissions by emitting carbon dioxide (CO2) via urea hydrolysis, and nitrous oxide (N2O) via soil biological activity... Submission of papers to scientific journals will enable findings and recommendations to be peer-reviewed before adoption by grain growers and policy makers...

Cropping is expanding in the southern High Rainfall Zone (HRZ) and it is important that we provide farmers with management options that minimise greenhouse gas emissions without reducing productivity... Nitrous oxide emissions in excess of 3 kg nitrogen/hectare/year (equivalent to 1460 kg of carbon dioxide equivalents) have been measured when a high fertility legume pasture in the southern high rainfall zone was sprayed out and cropped with wheat... The management and mitigation options that we are testing in this project are direct drilling of wheat compared to conventional cultivation and the application of a nitrification inhibitor dicyandiamide (DCD), which temporarily shuts down the microbes in the soil nitrogen cycle that convert ammonium to nitrate, and slows the rate of nitrous oxide emission from the soil...

An improvement in the efficiency of soil nitrogen cycling is expected to reduce nitrous oxide emissions... Existing farmer networks (Southern Farming Systems - Hamilton Branch, Horsham East Top Crop Group and the Birchip Cropping Group) will be used to help develop the key messages, so that they clearly demonstrate their relevance and importance to commercial cropping farms... Key extension messages at field days and fact sheets will focus on efficient nitrogen use by utilising existing tools (ie Yield Prophet, deep soil testing) for more informed nitrogen fertiliser decision making...
