Abstract

The dataset provides data on global cropland nitrogen flows for the year 2000 and 2010 at country level simulated by GLOBIOM. The nitrogen flows include N fertilizer, N manure, N fixation, N deposition, and harvested N. GLOBIOM (Global Biosphere Management Model) is a global partial equilibrium model allocating land-based activities, i.e. management of cropland, livestock systems and forestry, under land availability constraints, to maximize the sum of producer and consumer surpluses. In a recent version, the N cycle in global agricultural systems, including cropland, pasture and livestock systems, and in related human food systems was implemented in GLOBIOM. All biomass flows in GLOBIOM were transformed into N flows, and further accounted for additional N flows, including crop residues, biological nitrogen fixation (BNF), manure and fertilizer application, atmospheric deposition and N losses through leaching and gaseous of NH3, NOx, N2O, and N2. A description of the variables and associated data sources is available in the spreadsheet named ?BasicInfo".
