摘　　要：Nitrogen is an essential nutrient that supports life,but excess N in the humanenvironment system causes multiple adverse effects from the local to the global scale.Sustainable N management in agroecosystems,therefore,has become more and more critical to address the increasing concern over food security,environmental quality and climate change.Australia is facing a serious challenge for sustainable N management due to its emission-intensive lifestyle(high level of animal-source foods and fossil fuels consumption)and its diversity of agricultural production systems,from extensive rainfed grain systems with mining of soil N to intensive crop and animal production systems with excessive use of N.This paper reviews the major challenges and future opportunities for making Australian agrifood systems more sustainable,less polluting and more profitable.
