Abstract
A mechanized harvesting system consisting of a feller-buncher and a grapple skidder was examined to quantify soil bulk density changes in a central Appalachian hardwood forest site. Soil bulk density was measured using a nuclear gauge pre-harvest and post-harvest systematically across the harvest unit and on transects across skid trails. Bulk density also was measured in the skid trails in a subset of the transects after the first 10 loaded machine passes. Post-harvest soil bulk density of 954.4 kg/[m.sup.3] was not significantly different from the pre-harvest bulk density of 925.2 kg/[m.sup.3] across the site. Grapple skidding resulted in significant ...
