Abstract
Description
This dataset contains simulation output from agroecosystem models representing three Swedish yield survey districts with contrasting agroecological conditions: 1211 – Trelleborg, 0513 – Mjölby, and 0321 – Enköping. Districts are identified in the dataset by both their ID code (SKO) and the name of the closest major town.
The dataset includes estimates of nitrogen losses expressed in kg N ha⁻¹ yr⁻¹ in the forms of nitrate leaching (NO₃), nitrous oxide emissions (N₂O), and ammonia volatilisation (NH₃).
Results are provided for multiple management scenarios, including a reference management and scenarios with different combinations of intermediate crop cultivation and harvest of non-food agricultural biomass for anaerobic digestion. Simulations were conducted using the APSIM and DNDC models under multiple weather years (2014–2023) and over four consecutive crop rotation cycles for each location.
The data are delivered as a tab-separated text file (.tsv) and can be opened with any text editor, spreadsheet program (e.g. Excel) or statistical software (e.g. R, Python). The file contains 671 rows (including a header row) and 46 columns in total, with six columns describing the simulation context: SKO, Location, Weather_year, Cycle, Rotation_year, and Crop.
The remaining 40 columns contain model outputs. Each of these columns corresponds to a unique combination of scenario, model, and nitrogen compound (e.g. S1_APSIM_N2O, S3_DNDC_NO3, etc.).
No personal or sensitive data are included.
