Extended Data Fig. 2: Fertilizer, manure, manure percentage, deep-placement percentage, straw incorporation change for different scenarios toward 2050.
From: Agricultural management practices in China enhance nitrogen sustainability and benefit human health
a, Fertilizer change. b, Manure change. c, Manure percentage change. d, Straw incorporation change. e, Deep-placement percentage change. BAU, business as usual, assumes no interventions; POL, increase organic fertilizer use at a rate of 5% every 5 years and replace inorganic amount; SUG, fertilizer and manure are jointly reduced to recommended nitrogen application rate; M50 scenarios would increase manure percent to 50% gradually; SUG50 is combined of SUG and M50. The figures show specific values for these independent variables for different scenarios that are used for scenario analysis.
