Christine Jones -- Nitrogen: The double-edged sword

The use of inorganic nitrogen in agriculture is recognized as a highly inefficient - and polluting - practice. Globally, over $100 billion of nitrogen fertilizers 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.

The comments should be full of people awakening to the truth. Why do they reject what helps them? This is crazy, mind-blowing information for those who don't know yet.
