Optimal redistribution of nitrogen fertilizer among countries - EurekAlert
Helena Kahiluoto and colleagues quantified the optimal redistribution of nitrogen input for production of maize, rice, and wheat among countries and sub-national regions. Optimal redistribution of today’s level of nitrogen use would increase global crop production by 12%. Reducing the optimally redistributed nitrogen use to 33–43% of the current input, as Earth system scientists advise, would entail a 7–16% drop in global production.
