Description :
The aim of this study was to quantify the effect of variable freeze-thaw cycles and soil moisture conditions on aggregate stability of 3 soils (silt, structured clay loam-clay A and levelled silty clay loam-clay B), which are representative of 2 erosion prone areas in southeastern Norway. A second aim was to compare aggregate stabilities measured by the Norwegian standard procedure (rainfall simulator) and the more widely used wet-sieving procedure. Freezing and thawing decreased the rainfall stability of all soils, but the effect was more severe on the silt soil.
