Soil compaction in central Oregon volcanic ash soils and the subsequent effects on residual ponderosa pine growth

Creator:: Parker, Robert T.
Abstract:: Although previous research in central Oregon has shown soil compaction can lead to a decline in site productivity, the subject is not understood well enough to predict the growth changes resulting from a given level of soil compaction. A study was initiated to relate the basal area, height and volume...

Restoring productivity of compacted forest soils with tillage

Creator:: Whitaker, Carol Anne
Abstract:: Tillage of forest soils compacted by ground-based logging systems is a practice that is becoming widely accepted in the Pacific Northwest. However, past research has failed to adequately define the conditions and specifications that particular tillage operations should meet in order to produce the maximum growth response from planted seedlings....

Effects of tillage-induced soil compaction on carrot seedlings emergence and yield

Creator:: Thomasson, James E.
Abstract:: The effects of five tillage treatments on soil bulk density and mechanical impedance were examined on Newburg sandy loam soil in the Willamette Valley, Oregon, in 1987. Subsequent effects on seedling emergence and yield of carrots (Daucus carota L., cvs. Orlando Gold and Royal Chantenay) were also measured. Mechanical impedance...

Tilling compacted forest soils following ground-based logging in Oregon

Creator:: Andrus, Charles W.
Abstract:: Implements for tilling compacted forest soils were tested on sites logged with ground-based machines in Oregon. The sites covered a variety of soil conditions ranging from a clay loam to a rock7 2C2 iplemeflts tested included disk harrows (four aies), brusa blades (three sites), standard subsoiler tines (two sites), wing.-...

Shovel logging and soil compaction : a case study

Creator:: Floch, Rick F.
Abstract:: Shovel logging is a relatively new ground-based method of yarding tinther. It involves moving logs from stump to landing by successive swinging with a hydraulic excavator modified into a log loader by replacing the shovel bucket with a grapple. Loaders used in shovel yarding can weigh in excess of 100,000...

Competitive relations for soil water in an experiment of soil compaction and organic residues in a young ponderosa pine-mixed shrub community

Creator:: Swearingen, Kurt A.
Abstract:: An experiment was established in 1992 in the central Sierra Nevada Mountains of California to assess the effects of high levels of surface organic residues, severely compacted soil, and shrub competition on the development of mixed conifer plantations. This study was conducted in 1997 to determine if selected combinations of...

Response of Soil Temperature, Moisture, and Respiration Two Years Following Intensive Organic Matter and Compaction Manipulations in Oregon Cascade Forests

Creator:: Gallo, Adrian Carlos
Abstract:: Forest soils contain a substantial portion of global terrestrial carbon stores. Forest management can influence the soil carbon pool and how soil organic matter functions. The long-term productivity of forests is an ongoing goal where land managers utilize biomass and timber. A site-specific understanding of intensively managed forests can ensure...
