Short summary
This study explores the link between soil magnetic susceptibility and cation exchange capacity (CEC) to improve prediction models for CEC in European soils. The results show that magnetic susceptibility significantly enhances CEC prediction in sandy soils, achieving high accuracy (R2 = 0.94). This offers a rapid, cost-effective way to estimate CEC, emphasizing the value of geophysical data integration in soil assessment.
