RT Journal Article SR Electronic A1 Kozlovsky Dufková, Jana T1 Influence of low temperatures on aggregate disruption of heavy clay soils JF Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis YR 2014 VO 58 IS 2 SP 161 OP 168 DO 10.11118/actaun201058020161 UL https://acta.mendelu.cz/artkey/acu-201002-0018.php AB Heavy clay soils that are normally resistant to wind erosion, from study site Ostrožská Nová Ves situated in the foothills of the Bílé Karpaty Mountains, Czech Republic, were a subject of laboratory analyses. The analyses should found out the influence of overwinter processes on disruption of soil aggregates and thus reason of vulnerability to soil loss by wind. Two overwinter processes were observed - freezing and thawing, and freeze-drying of the soil. Both processes have indicated the increasing of erodible fraction in dependence of water content of analysed soils. Exposed frozen clay soils that freeze-dries during the winter in the foothills of Bílé Karpaty, leaves soils highly erodible in late winter and early spring.
