These treatments will be used to determine the implications of different levels of woody-biomass removals. These treatments will be used to determine the growth potential enhancements from full site resource allocation to the crop and the addition of nutrient amendments. Treatments 11 and 12 will be compared with treatment 2 to determine the impacts of mechanical harvesting on soil properties and stand productivity, and the amelioration potential of tillage, all under the conventional bole-only harvest plus weed control and fertilization regime. All four blocks have been established in the McDonald Tree Farm SW Washington on the Boistfort or Melbourne soil series.
Soils are susceptible to productivity impairment when compacted.
