Abstract

We used APSIM to compare the profit and risk (economic and environmental) for a farmer in the medium rainfall zone of South Australia who applied the same amount N to wheat every year with a farmer that was guided by POAMA to tactically change rates. Over the 30 year period from 1981 to 2010 a farmer following POAMA would have received the correct guidance 19 times and incorrect guidance 11 times. Depending on the amount of nitrogen (N) used, following POAMA increased the gross margin by $23 or 9%. Forecasts didn’t reduce the risk of nitrous oxide emissions or N leaching. Under the assumptions of this simulation study, the most economically sound N strategies come from a focus on fertiliser N use efficiency which keeps rates at levels where losses to de-nitrification or leaching are minimal.
