Subsoiling as Site Preparation on Ponderosa Pine Plantations of the Yakama Nation Forest

Early logging efforts on the Yakama Nation Indian Reservation in Washington State featured 100 percent piling of logging slash, with minimal concern for soil compaction. Observations of regeneration growth and development indicate that soil compaction may play a role in reducing tree growth on timbered land that was harvested in the era before logging practices were modified to minimize compaction. This article describes a project to document soil compaction on Yakama Nation forest land, compare the operations of two separate machines in subsoiling to break up soil compaction, and examine the growth of seedlings in response to subsoiling.
