Adequate crop yields to feed 7.8 billion people today, and nearly 10 billion by mid-century (Vollset et al. 2024 ), depend on large amounts of nitrogen (N) input, which in turn represent an inherent weakness in our global food production system. The challenge has nothing to do with N supply as that is virtually unlimited.
