Aspen Utilization In The Northern United States, D.I. Maass, L.C. Irland, S.D. Salisbury Jan 1990

Aspen Utilization In The Northern United States, D.I. Maass, L.C. Irland, S.D. Salisbury

Aspen Bibliography

Aspen is an important resource to the northern United States and in Quebec and Ontario. Roundwood use for pulp in the Lake States has remained stable at 2 million cords since 1981, while use for flakeboard has increased five-fold. Despite the near doubling of use in this decade, real stumpage prices for aspen have remained stable, and the mill delivered prices have declined. The pulp industry is less cost and supply sensitive than the flakeboard industries. Substitutions of other species will occur when aspen supply declines. Resource decisions in the future will be driven by both markets and politics.

Aspen Site Index As Related To Plant Indicators, D.K. Walters, J.P. Sloan, V. Kurmis Jan 1990

Aspen Site Index As Related To Plant Indicators, D.K. Walters, J.P. Sloan, V. Kurmis

Aspen Bibliography

Eighty-five fully stocked, even-aged, aspen stands representing a wide range of ages were examined. Using published site index equations, the site index of these stands was estimated. A second available indicator of the site quality was the soil productivity group used by the Soil Survey. Each of these site quality indicators was related to synecological coordinates (moisture, nutrient, heat, light) of 85 stands. In this case, synecological coordinates were identified through the use of indicator plant species (synecological coordinates).


Sorting Aspen Bolts And Drying Aspen Flitches For Sdr, R.S. Boone Jan 1990

Sorting Aspen Bolts And Drying Aspen Flitches For Sdr, R.S. Boone

Aspen Bibliography

Log sorting is necessary when processing aspen saw-dry-rip (SDR) to select optimum log diameter and to minimize number of logs with dark-colored centers. Wetwood, which is difficult to dry, is commonly associated with these dark centers. SDR processing involves drying 7/4- to 8/4-thick live-sawn flitches. Drying the flitch and then sawing studs produces straighter studs than sawing first and drying in stud form. High-temperature kiln drying (230 o F to 240 o F) has given good results with several species (such as, basswood and yellow-poplar). For species likely to contain wetwood (aspen, cottonwood, willow), high-temperature drying is not recommended. A …

Aspen Wood Products Utilization: Impact Of The Lake States Composites Industry, John A. Youngquist, Henry Spelter Jan 1990

Aspen Wood Products Utilization: Impact Of The Lake States Composites Industry, John A. Youngquist, Henry Spelter

Aspen Bibliography

The utilization of Lake States aspen for value-added products has increased dramatically in the last 15 to 18 years. This paper reviews aspen utilization for solid and composite wood products since 1970, discusses the forecasted future demand for wood-based composites, and reviews research that may influence future utilization of aspen in the Lake States.


Development Of An Aspen Sucker Stand Following Irrigation And Fertilization, G.W. Wyckoff, D.W. Einspahr, M.K. Benson Jan 1990

Development Of An Aspen Sucker Stand Following Irrigation And Fertilization, G.W. Wyckoff, D.W. Einspahr, M.K. Benson

Aspen Bibliography

A 16-18 year-old aspen stand was harvested in 1969. Aerial biomass components were determined and soils evaluated. Treatments of fertilizer, irrigation, fertilizer + irrigation and control were applied over a seven year period following harvest. Stand measurements were taken periodically over 18 years. Fertilization produced growth increases of 45-55 percent. Height, diameter, and stems per acre were affected by treatments. Guidelines for fertilizer application were developed from leaf tissue analysis.
