The change in wheel track surface soil bulk densities was determined after a mechanized thinning in a northern red oak stand. Mean bulk density values of the 0 to 5 cm surface of the wheel tracks immediately after felling, bunching, and skidding were: 0.80 g/cc on the high use areas; 0.77 g/cc on the low use areas; and 0.42 g/cc in the undisturbed areas. No significant differences in surface soil bulk densities were found between several loading treatments using a four-wheel drive articulated forwarder. The data indicate that initial passes of the equipment produce most of the disturbance. No significant recovery in wheel track soil bulk densities occurred during the year following harvest regardless of treatment. North. J. Appl. For. 5:120-123, June 1988.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
