A farm level model is used to assess effects of different SOC management practices. Analysis of the trade-offs between effects on yield and input costs on farm gross margins (GM) GM effects: more sensitive to crop yield changes than to changes in input costs. Maximum positive effect on GM greater for Aragon (Spain) compared to Scotland (UK). In total three SOC measures are found to be relatively robust to assumptions made.
