Christine Jones -- Nitrogen: The double-edged sword

The use of inorganic nitrogen in agriculture is recognised as a highly inefficient - and polluting - practice. Globally, over $100 billion of nitrogen fertilisers are applied to crops and pastures every year. Between 10 and 40% of the applied nitrogen is taken up by plants. Much of the remaining 60% to 90% is returned to the atmosphere as ammonia or nitrous oxide - or leached to aquatic ecosystems as nitrate. Due to its high mobility, inorganic nitrogen has become a key stressor for terrestrial, freshwater and marine environments. This session will explore how a whole-farm approach to the restoration of soil biodiversity can replace the need for inorganic nitrogen fertilizers.
