An increasing frequency of environmental stresses on crop yields, concern of air and water quality, and financial pressure all warrant the need for a focus on nutrient use efficiency (NUE). For the values to be meaningful at the farm level, a relationship between management decisions and NUE should be identified. The status and trend of NUE in U.S. cropping systems will be discussed to provide a baseline understanding of where we are with the use of this metric and where measuring NUE is beneficial.
