Soil water repellency and chemical soil properties in a beech forest soil Spatial variability and interrelations

摘要

Higher solute input due to stemflow infiltration causes enhanced soil acidification near the tree base. Infiltration driven alteration of chemical soil properties like pH, and carbon to nitrogen ratio (C/N) and particle surface properties like oxygen to carbon ratio (O/C), may also affect soil wettability with a trend to increased soil water repellency (SWR) with increased acidity. Our study provides a link between chemical soil quality and physical behavior with respect to soil water infiltration and SWR, respectively in a beech forest soil.
