DLEM-simulated N and P budgets in the Mississippi River Basin during 1901-2018

This dataset displays the annual nitrogen (N) and phosphorus (P) budgets in the Mississippi River Basin during 1901-2018. The major N and P inputs in terrestrial ecosystems include synthetic N and P fertilizer, livestock manure N and P, atmospheric N deposition, and biological N fixation (BNF). Meanwhile, the major N and P outputs include harvest removal of N and P, nitrous gas (NH₃, N₂O, NO, N₂) emissions, and riverine N and P exports. N and P balances are the differences between all N or P inputs and all N or P outputs. N and P fertilizer, manure N and P, and N deposition are data-based input variables. BNF, harvest N and P, NH₃ emission, N₂O emission, N₂ emission, NO emission, and riverine N and P exports are simulated by the Dynamic Land Ecosystem Model (DLEM).
