|Atmospheric nitrogen is not directly usable by most living things. In nature, specialized microbes in soils and bodies of water convert nitrogen into ammonia — a crucial form of nitrogen that life can easily access — through a process called nitrogen fixation. Princeton University researchers have found evidence that nitrogen fixation can be facilitated by metals that are more abundant in soil, which suggests that nitrogen fixation may be more resilient to molybdenum scarcity than previously thought. Princeton is a NYSERNet member.
