Read the full story from the University of Maryland Center for Environmental Science.

A new paper published in Nature Food offers the first comprehensive comparison of the most advanced international efforts to measure how nitrogen is managed in agriculture. Zhang et al synthesize results from nearly thirty researchers from ten different research groups across the world, including universities, private sector fertilizer associations, and the United Nations Food and Agriculture Organization (FAO). They each estimated how much nitrogen is added to croplands as fertilizer and manure, how much of the added nitrogen is harvested in crops, and how much is left over as potential environmental pollution.
