DescriptionSoil penetration-resistance and soil-humus frequency were measured on 86 progeny-test plantations in southwestern Oregon to determine the effects of yarding method and slash treatment on soil compaction and humus, and a disturbance index was calculated for each plantation. Compaction and humus loss were more severe on tractor-yarded, machine-piled plantations than on cable-yarded, broadcast-burned plantations. Machine piling and burning of slash did not increase compaction or humus loss significantly more than broadcast burning on tractor-yarded plantations. Within-plantation variation in soil compaction was greater on tractor-yarded, broad-cast-burned plantations than on tractor-yarded plantations from where stumps were removed.
