Physical soil degradation induced by deforestation and slope modification in a temperate‐humid environment
Authors:ME Varela  E De Blas  E Benito
Abstract:Between February 1998 and March 1999 physical soil degradation was studied in temperate‐humid NW Spain after deforestation and slope modification. Changes in bulk density, total porosity, pore size distribution, aggregate stability and soil mechanical strength indicated the degradation process. Slope levelling produced the greatest impact. A rapid recovery of physical properties was observed, with the exception of those related to the soil mechanical strength. The increased soil erosion needs agronomic studies to understand the long‐term benefits and adverse aspects of the land‐use changes. Copyright © 2001 John Wiley & Sons, Ltd.
