The project will do more than provide a general awareness of climate change and its implications for agriculture... High-profile on-ground activities in Queensland and NSW will address each of the Climate Change Research Program (CCRP) priorities: managing emissions, better soil management, and adapting to a changing climate... The activities will help farmers and advisers to understand the implications for management on their own farms and start developing their own adaptation strategies...

" 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...

Sally was with the Victorian Department of Primary Industries (DPI), where in recent years she was prominent in researching the degree to which nitrous oxide is contributing to climate change and ways for growers to manage this... Before working at the Victorian DPI, Sally worked as a soil scientist for the Institute for Crop and Food Research in New Zealand... Given that in the zones, with decreasing rainfall and rising temperatures, cropping will become increasingly viable, Sally discovered and confirmed this as an important issue for Australian agriculture...

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...
