Data from: Carbon in above- and belowground harvest residues of silage maize under contrasting nutrient regimes

This dataset accompanies the article titled “Carbon in above- and belowground harvest residues of silage maize under contrasting nutrient regimes”. Dataset Description This dataset contains plot-level C inputs for silage maize at Askov LTE, Denmark (B5-field) based on a sampling campaign in autumn 2023. It Includes field-measured values and C-TOOL allometric estimates. File: MaizeC.csvUnits: Mg C ha-1 Key column Comments / definition Treatment Levels: 1PK, ½NPK, 1NPK, 1½NPK, ½AM, 1AM, 1½AM. (NPK = mineral; AM = cattle slurry). Plot level C inputs from silage maize Yield_DM Silage maize dry-matter yield (Mg ha⁻¹). Yield_C C in the harvested main product (from Yield_DM). Stubble_C Basal stem residue remaining after harvest. Brace_C Above-ground brace-root segments assigned to aboveground harvest residue. Total_above_C Total aboveground C in harvest residues (Stubble_C + Brace_C). Core_rootsC Fine root biomass from core auger, 0–30 cm. Crown_rootsC Excavated crown root biomass, 0–30 cm. Total_below_C Total belowground C (Core_rootsC + Crown_rootsC (0–30 cm)). Total_input_C Total C input to soil in all harvest residues (stubble, brace roots, core roots and crown roots). C-TOOL allometric estimates (model-derived) Total_above_Allo Total aboveground C in harvest residues (stubble). Total_below_Allo Total belowground C in harvest residues (roots, rhizodeposition) in 0-30 cm depth. Total_input_C_Allo Total C input to soil in all harvest residues (stubble, root biomass and rhizodeposition). Baseline soil C and N measured in 2020 Soil total C Soil total C concentration (g 100 g-1). Soil total N Soil total N concentration (g 100 g-1). C/N (-).
