Soil compaction was assessed in terms of soil strength as measured with a penetrometer. Penetrometer resistance was measured on virgin soil and on the same soil after one and after five passes of a 7,610 kg tractor. Also, comparative studies were made of strength profiles of soils in arable fields a
## Abstract Between February 1998 and March 1999 physical soil degradation was studied in temperateโhumid 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
## Abstract Twelve soilโpreparation techniques used in afforestation were applied and 16 environmental variables were measured to test their effects on vegetation abundance, diversity, and cover in semiarid abandoned farmland located in southeastern Spain. The soilโpreparation techniques consisted
