Predicting Nitrogen cycling and losses in Australian cropping systems
Excessive rainfall has hit northern growers over the past six months.\n \nWith water logging across paddocks, growers are at heightened risk of losing nitrogen from denitrification, and it\u2019s an issue GRDC is keen to understand better.\n \nRecent research supported by GRDC and led by Senior Research scientist at the New South Wales Department of Primary Industries, Dr Graeme Schwenke, found that on average, paddocks with waterlogging could lose 28 per cent of nitrogen from denitrification.\n \nTo get the complete picture of nitrogen cycling and the conditions under which growers can lose nitrogen from the soil, GRDC has launched a new project to investigate how to better predict nitrogen cycling and losses in Australian cropping systems with a focus on augmenting measurements to enhance modelling.\n \nIn this podcast Dr Schwenke discusses the state of play on the ground right now, and the value of further research into nitrogen cycling.\n\nContact: \nGraeme Schwenke\nNSW DPI\ngraeme.schwenke@dpi.nsw.gov.au\n\nMore information:\nGRDC Update Paper: Nitrogen volatilisation: Factors affecting how much N is lost and how much is left over time\n\nProject code: UOQ2204-010RTX\nLearn more about your ad choices.
