Creator:: Wagai, Rota
Abstract:: Most soil organic C is in a stable form, associated with clay minerals in the upper soil profile. Upon environmental and land-use changes, stable soil C is subject to losses, which influence the global C cycle and the productivity of terrestrial ecosystems. However, mechanisms controlling soil C destabilization are not...

Creator:: Landsberg, Johanna Dobrot
Abstract:: Tree growth and soil nutrient responses to prescribed underburning were determined for a period of up to 12 years at four sites in northcentral and central Oregon ponderosa pine stands (Pinus ponderosa Dougl. ex Laws). Differences reported are significant at a = 0.10. During the first 4-growing-season-measurement period after underburning,...

Creator:: Bates, Jonathan D.
Abstract:: Since the late 1880's western juniper has expanded in range and increased in density in sagebrush-bunchgrass, riparian, and forested plant communities of the Pacific Northwest. Succession to western juniper woodland has been shown to reduce the productivity and diversity of the understory component, result in concentration of soil nutrients beneath...

Creator:: Velazquez-Martinez, Alejandro
Abstract:: The objectives of this research were to study: a) the effect of thinning and treatments consisting of pruning and multinutrient fertilization on aboveground biolnass increment, growth efficiency (GE), and foliar nutrients; b) the influence of topoedaphic variables (soil nutrients, slope, aspect, and rock content) and foliar nutrients on both leaf...

Creator:: Borchers, Jeffrey G.
Abstract:: The effect of physical factors such as soil structure, bulk density, parent material, and topographic variables on soil C and N dynamics and ectomycorrhizal inocululu potential in forests of southwest Oregon were investigated In the high-elevation white fir (Abies concolor (Gord. & Glend.) Lindl.) zone, two old poorly-vegetated clearcuts with...
