Humus-NPK balances of crop rotations: coefficients, validation data and multi-objective optimisation results

Supplementary data for the manuscript Balancing soil humus, nitrogen and income in organic crop rotations: a multi-objective decision-support model with farmer profiles (manuscript submitted for publication). Contents: crop and model coefficients of the coupled humus and N-P-K balance model (residue regressions, humification and mineralisation coefficients, removal norms, seed and fertiliser contents, losses, yield ranges, 2021 prices in UAH and EUR); humus balance and stock values transcribed from Kudria et al. (2024, doi:10.31073/agrovisnyk202401-08) with a script that reproduces the cross-regional validation of the humus module; a term-by-term comparison of NPK balance coefficients with an independent long-term study; and the results of the multi-objective linear programming of 2176 five-field rotations in organic and conventional mode (Pareto and Slater sets, farmer-profile plans, price-of-fertility curves, worked example). Values transcribed from third-party publications remain attributable to their original authors; see README.md.
