This paper, was drafted by GPNM’s NUE Task Team led by Dr. Terry Roberts and Dr. Rob Norton (International Plant Nutrition Institute) and Dr. Eric Davidson (University of Maryland Center for Environmental Sci-ence). It offers the technical basis and supporting research for using Ni-trogen Use Efficiency (NUE) as a performance indicator to improve global food production, and control the potential harmful environmental impacts of excess nitrogen-based compounds from manufactured and animal waste fertilizers. NUE implies a more precise application of nutrients that is based on current agronomic principles, in combination with other fac-tors like soil health, water availability, climate, and type of crop. The work on NUE is intended to support the assessment tools and techniques re-lated to the eventual articulation of targets within the scope of the Sus-tainable Development Goals (SDGs).
