ST. PAUL, Minn. — University of Minnesota researchers have created a tool for quantifying adverse impacts of nitrogen, identifying where reduced use will have the most benefit.
Humans have more than doubled the amount of reactive nitrogen in the environment since the Industrial Revolution, with adverse consequences that include air and water pollution, biodiversity loss, ozone depletion, water acidification and climate change.
But what exactly do these impacts mean for people and communities, and how can we can figure out where and how much to most effectively reduce the amount of new nitrogen entering the environment?
To adequately account for the. . .
