The potential of inhibitors for the mitigation of nitrous oxide emissions from animal production systems, in south-eastern Australia An automated system linking 8 enclosure chambers to a Fourier Transformed Infrared Spectrometer (FTIR) will be used to measure N2O, CO2 and CH4 emissions respectively from treatments described below at the core site at DemoDairy, Terang (38o14 'S, 142o55 'E), in south-west Victoria... The potential for increases on pasture productivity from the use of inhibitors requires testing under Australian conditions... An understanding of the potential for inhibitors to reduce direct nitrous oxide emissions from urine deposited on pasture in animal production systems, specifically dairy production systems...

The project focused on colour stability (darkening) of Asian noodles and has provided strategies for improvement of Australian wheat varieties and better management of quality of grain shipments going to high value markets... Significant research is still required to understand the genetic and environmental control of constituents that determine the creamy to yellow colour of noodles and pasta variation that can occur along the production to use chain... Darkening in noodles measured as a loss in brightness (CIE L*) was separated into two main time periods, 0-4hours and 4-24hours...

Urease inhibitors act by slowing the rate of urea hydrolysis (the process by which N is released from a granule), by inhibiting the action of the enzyme urease, and by doing this the elevated pH hotspot that occurs around the granule is lessened and this reduces the risk of NH 3 loss... The paper presents laboratory and field experiment data that investigated the impact of the urease inhibitor NBPT (Green Urea TM 7 or 14 in Australia), on rates of urea and NH 3 loss... The experiment showed that NH 3 loss in autumn was greater than in spring (Table 1) and that whilst the inhibitor was effective at both times, the real benefit in terms of N saved was only seen in autumn...
