Global cropland nitrogen flows for the year 2000 and 2010 simulated by GLOBIOM

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.
