We developed a biogeophysical model called Agro-C to assess the regional carbon budgets of agroecosystems on a large scale. The model consists of two submodels, Crop-C and Soil-C. Crop-C simulates crop photosynthesis, autotrophic respiration and net primary production (NPP). Soil-C simulates soil he...
