Estimated soil carbon inputs and modeling results for Swedish arable land under rotation in areas approved for environmental compensation

This data set results from researching the effects of removing crop residues and cultivating intermediate crops (IC) on long-term soil organic carbon (SOC) in Swedish arable land areas approved for environmental compensation. Thus, it contains data considering five different scenarios: S1, a base scenario with no residue removal nor IC cultivation; S2, an alternative scenario with IC cultivation; S3, an alternative scenario where crop residues are harvested for biogas production with the return of digestate as soil amendment; S4, an alternative scenario with IC cultivation and harvest of crop residues for biogas production; and S5, an alternative scenario with IC cultivation and where both crop residues and IC biomass are harvested for biogas production. Estimations of SOC inputs are based on estimated biomass availability for each yield survey district (SKO) from the previously published dataset (Barrios Latorre, S. A. (2024), information collected from the statistics database of the Swedish Board of Agriculture (Jordburksverket), and Statistics Sweden (SCB, 2023). It considered all the Swedish SKOs where removing residues and cultivating intermediate crops is technically possible. The geospatial data containing the boundaries of the SKOs can be requested from Jordbruksverket or accessed directly from the previous dataset (https://doi.org/10.5878/t9ey-ac36). Estimations of SOC inputs are differentiated by source: aboveground biomass (AGB), belowground biomass (BGB), and organic amendments (OA). Furthermore, the total SOC at steady state (Css) for each scenario was estimated using the Introductory Carbon Balance Model (ICBM) (Menichetti et al., 2024). The file contains 85 rows (SKOs) and 34 columns. References Barrios Latorre, S. A. (2024).
