Soil erodibility is the resistance of soil to detachment by rainfall impact or surface flow force. Surface soil samples were taken from 17 soil series in four seasons to determine the erosion sensitivity of the soils of Çanakkale Umurbey Plain (K–factor) by using wet sieving method and the equations of Wischmeier and Smith (1978) nomograph' s equation. Differences in K factors and aggregate stabilities by season were compared with repeated measurement variance analysis. Aggregate stabilities of the soil samples taken at different seasons varied between 2.76–4.35% (low) and K–factors varied between 0.20–0.30 (highly erodible). Vegetative measures and especially organic matter supplementation should be emphasized as a soil conservation method to improve the aggregate stabilities and to reduce K–factor values.
