Short summary
Healthy soils rely on plant biomass, especially roots. We studied how wheat cultivar development interacts with soil erosion-deposition in carbon inputs. Tillage erosion reduced total biomass, while modern varieties yielded more grain but returned less carbon. Simulations showed newer cultivars are more drought-sensitive, revealing a trade-off between high yields and soil health.
