" 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... Technology to reduce spray drift GCTV: Drift Reducing Technology..

Growers strengthen their position when their storage facilities allow flexibility with grain handling and timing of sales... As a bonus, many of the strategies used to minimise pest problems also significantly improve storage conditions for maintaining grain quality... Examples include: the ability to have fans automatically step through the 3 important stages of aeration cooling - "continuous", "purge", "protected"; an additional auto function that now excludes high humidity air (>85% RH) in all three of these stages; a setting that can be included that adjusts fan operations to cater for fans fitted to silos with air flow rates higher then the standard 2 - 3 L/s/t flow rates...

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...

Around the world cereals, oilseeds and pulses that make better use of applied nitrogen fertiliser are under development.. The idea looks simple on paper - endow all the major cereals, legumes and oilseeds with an enhanced potential to take up, assimilate, store or move nitrogen into grain thereby maximising yield and grain quality while reducing costs and waste... Overall, the signs are promising that NUE traits can be developed, allowing nitrogen's yield-enhancing value to be retained while diminishing its spiralling costs...

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...

Before biochar can be widely adopted in agriculture, better understanding is needed of its properties and how it interacts - both positively and negatively - with the soil... Gas chambers are used to measure greenhouse gas emissions from a soil amended with biochar in Western Australia... Applications of biochar to soil have demonstrated improvements in the physical structure of the soil by: increasing water-holding capacity (in sandy soils); reducing the tensile strength of hardsetting soil; altering the soil thermal properties; and improving physical conditions for increased earthworm populations...
