  1. The imprint of coarse woody debris on soil biological and chemical properties in the western Oregon Cascades

    The abundance and spatial heterogeneity of coarse woody debris (CWD)

  2. Comparison of Disturbed and Undisturbed Soil Core Methods to Estimate Nitrogen-Mineralization Rates in Manured Agricultural...

    To the best of our knowledge, one or more authors of this paper were federal employees when contributing to this work. This is the publisher’s final pdf. The published article is copyrighted by Taylor &...

  3. Predictive mapping for the delineation of landtype association units in the Fremont National Forest, Oregon

    Predictive Soil Mapping (PSM) has recently become an attractive method for soil scientists wishing to develop a more objective and efficient approach to mapping soils. Due to the potential PSM has for reducing...

  4. Soil physical conditions and nitrogen fixation of soybeans (Glycine max. Merrill, var. Chippewa 64)

    The effect of soil water suction and soil temperature on rates

  5. Soils of the Oregon coastal fog belt in relation to the proposed "Andisol" order

    A study was conducted to evaluate the properties of soils in

  6. The Terroir of Pinot Noir Wine in the Willamette Valley, Oregon : A Broad Analysis of Vineyard Soils, Grape Juice and Wine...

    Terroir is determined by a combination of factors in the vineyard including the grape varietal, geology and soil, soil hydrology, physiography, and climate. Although most studies have examined regional...

  7. Soil solution chemistry, profile development, and mineral authigenesis in several western Oregon soils

    Clay mineral genesis was studied in soils representative of several

  8. Response of Soil Temperature, Moisture, and Respiration Two Years Following Intensive Organic Matter and Compaction...

    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...

  9. Soil respiration, carbon and nitrogen leaching, and nitrogen availability in response to harvest intensity and competing...

    Management practices following forest harvest can affect long-term soil productivity through alteration of soil carbon (C) and nitrogen (N) pools, but processes contributing to change are poorly understood. I...

  10. Tree species-soils relationships in old-growth forests of the Oregon Coast Range

    Tree species directly and indirectly affect soil nutrient cycles. I sought to characterize soils and foliage associated with four common canopy tree species (Douglas-fir, western hemlock, western redcedar, and...
