Resumo: | Mallee farmers minimize downside risk in dry seasons by applying low rates of nitrogen (N) fertiliser to their cereal crops. The opportunity to respond to and capitalize on the better years is further limited as most inputs are applied upfront at sowing. We used an economic-risk decision model to identify a range of tactical N fertilisation options that increase net returns, while minimising risk for farmers with different risk attitudes. Importantly, we concluded that when accounting for long-term risks affecting farmers, the use of higher N rates can play a risk-reducing role in a highly variable environment like the Mallee.
