Soils of the reference stands -- Oregon IBP

Creator:: Brown, R. B. (Randall Barber), Parsons, Roger Bruce, 1932-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Field reconnaissance, soil sampling, and laboratory analyses were conducted to characterize the soils of the 50 by 50 meter forest community reference stand plots in and near the H. J. Andrews Experimental Forest. Soil descriptions, chemical and physical properties, soil classification, and nutrient capital information for mineral soils are summarized....

Soil variability, Oregon IBP: Annual report 1972

Creator:: Brown, R. B. (Randall Barber), Parsons, Roger Bruce, 1932-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Goals in 1972 included characterization of the soils of the Oregon IBP reference stands, development of information on the soils throughout the H. J. Andrews Experimental Forest, and evaluation of nutrient provision to the major kinds of soils. Field reconnaissance, soil morphology studies, and sampling were carried out. Lab analyses...

Litter controls of microbial community composition and function in forest soils

Creator:: Brant, Justin B.
Abstract:: Most carbon (C) transformations in soil are carried out by a diverse and complex soil microbial community. The size and composition of the soil microbial community is determined by poorly understood interactions between the quantity and chemical composition of plant inputs, as well as climate. Given the metabolic diversity of...

Characteristics of soil organic matter in two forest soils

Creator:: Crow, Susan E.
Abstract:: Soil organic matter (SOM) is the terrestrial biosphere's largest pool of organic carbon (C) and is an integral part of C cycling globally. Soil organic matter composition typically can be traced directly back to the type of detrital inputs; however, the stabilization of SOM results as a combination of chemical...

Movement of water through forested soils in steep topography

Creator:: Harr, R. Dennis (Robert Dennis), 1941-, Ranken, Darren W., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Field and laboratory studies are being conducted to describe the hydrologic properties of soil and to determine the timing pathway of precipitation and snowmelt water as it moved through forested soil on a steep slope. Hydrologic properties include hydraulic conductivity, porosity, pore-size distribution, moisture characteristics, stone content, and soil depth....

Vegetation and soils of watersheds 2 and 3, H. J. Andrews Experimental Forest

Creator:: Hawk, Glenn M., Dyrness, C. T., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Early in the planning of the Coniferous Biome program It was recognized that experimental watersheds 2 and 3 in the H. J. Andrews Experimental Forest might provide ideal study sites for certain phases of the Biome program. A study was funded during year 1 (1970) to provide necessary background ecological...

Response of soil microbial communities to physical and chemical disturbances: implications for soil quality and land use sustainability

Creator:: Chaer, Guilherme M.
Abstract:: The objectives of this thesis were to evaluate the responses of soil microbial communities to physical and chemical disturbances, and associate these responses with soil functional stability and changes in soil quality. The first study consisted of application of heat shocks (HS) to soils with contrasting land use history to...

Quantifying C and N contents and isotope signatures of SOM pools in the H. J. Andrews DIRT plots

Creator:: Keirstead, Heath
Abstract:: The mechanisms governing short- and long-term belowground carbon dynamics need to be understood. As part of a larger project developed to assess the effect of quantity and quality of litter inputs on the rate of soil organic matter (SOM) formation, I examined SOM in the H. J. Andrews Detritus Input...

Vegetation and soils of the Hi-15 watersheds, H. J. Andrews Experimental Forest

Creator:: Dyrness, C. T., Hawk, Glenn M., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Early in the planning of the Coniferous Biome research program, it was recognized that Experimental Watersheds 6, 7, and 8 in the H. J. Andrews Experimental Forest might provide ideal study sites for certain phases of the Biome program. A study was funded during year 1 (1970) to provide necessary...

Characterization of fungal and bacterial communities associated with mat-forming ectomycorrhizal fungi from old-growth stands in the H.J. Andrews Experimental Forest

Creator:: Hesse, Cedar N.
Abstract:: Mat-forming ectomycorrhizal (EcM) fungi represent a prevalent constituent of many temperate forest ecosystems and create dramatic changes in soil structure and chemistry. EcM mat soil have been shown to have increased microbial respiration rates and have been hypothesized to harbor unique assemblages of fungi and bacteria. The objectives of this...
