SOIL BULK-DENSITY, SOIL STRENGTH, AND REGENERATION OF A BOTTOMLAND HARDWOOD SITE ONE-YEAR AFTER HARVEST

The first year soil physical properties and regeneration measurements following harvest indicate ample regeneration on all treatments includ ing the landing areas. Comparisons included three machine systems (thr ee skidders) and a helicopter-yarded control that were field tested fo r harvesting a bottomland hardwood site under adverse conditions. The results also demonstrate a significantly greater number of tree stem c ount following the winter than the summer harvest. Results of the stat istical analysis of soil bulk density indicate that the soil had parti ally recovered from machine traffic one year after harvest.
