Functional profiles of soil microbial communities in second-growth Douglas-fir forests of the Pacific Northwest

Creator:: McGinnis, Megan L.
Abstract:: Forests are one of the largest repositories of terrestrial C. Understanding factors that drive organic matter transformations and nutrient efflux from these systems is therefore highly important. Temperate forests are of particular significance due to the large fraction of C that is stored below ground in the soil. Characterizing nutrient...

Acidifying soil for crop production : Inland Pacific Northwest

Creator:: Oregon State University. Extension Service, Washington State University. Extension, University of Idaho. Extension, Horneck, Donald Arthur, Wysocki, Donald John, 1952-, Hopkins, Bryan G., Hart, John M. (John Mervyn), 1947-, Stevens, Robert G., and Pacific Northwest Cooperative Extension
Abstract:: This publication is a technical and practical guide for soil acidification in commercial fields. It explains the soil chemistry involved, how to determine whether pH adjustment is feasible, and methods for acidifying soil. This guide is divided into five sections: • Understanding soil pH • The problem—iron chlorosis • Causes...

Influences of nitrogen on carbon dynamics in forest soil and density fractions

Creator:: Swanston, Christopher W.
Abstract:: Application of N fertilizer is a common forest management practice in the Pacific Northwest, yet the long-term influence of fertilization on forest soil properties is not well known. Although elevated N often increases mineralization of C and N from labile organic matter, negative effects have been documented in recalcitrant organic...

Best management practices for maintaining soil productivity in the Douglas-fir region

Creator:: Angima, S. D., Terry, Thomas A., Dobkowski, Alexander, Campbell, Steve, Grizzel, Jeffrey D., Harrison, Robert B., Heninger, Ronald L., Maguire, Douglas A. (Douglas Alan), Miller, Richard E., Page-Dumroese, Deborah S., Scott, William, Zabowski, D., and Oregon State University. Extension Service
Abstract:: This publication is a reference guide for forest soils productivity and management. Main topics include (1) understanding and managing risk, (2) soil characteristics that affect productivity, (3) soil survey information for forestland managers/management of soil erosion, (4) managing mass wasting risk, (5) managing soil disturbance, and (6) maintaining adequate nutrient...

Provenance, lifespan, and phylogeny : testing a conceptual framework for plant community management

Creator:: Benfield, Cara D.
Abstract:: Successful conservation management requires an understanding of how species respond to intervention. Native and exotic species may respond differently to management interventions due to differences arising directly from their native or exotic origin (i.e., provenance) or from differences in life-history or phylogenetic lineage that are associated with provenance. Thus, selection...

Susceptibility of riparian soil invertebrates to the herbicide triclopyr

Creator:: Moran, Patrick (Patrick William)
Abstract:: Riparian zones of Pacific Northwest forests have high species diversity and abundance and act as an important interface between the aquatic and terrestrial ecosystems. In addition, riparian zones comprise a significant portion of the total buffer zone established during commercial forest production to protect aquatic ecosystems from adjacent management activities....

Impacts of forest practices on surface erosion

Creator:: Sidle, Roy C.
Abstract:: Surface erosion can be initiated by forest practices such as timber harvest, road construction, and site preparation. A variety of management and control measures can help reduce this erosion. Surface erosion is generated by soil and operational conditions that are conducive to or cause disturbance and compaction. By using good...

Characteristics of dissolved organic matter (DOM) and its stabilization in forest soil

Creator:: Yano, Yuriko
Abstract:: Dissolved organic matter (DOM) plays an important role in transport of C and essential nutrients such as N, P and S. DOM is also critical for the formation of soil organic matter (SOM), which is the largest terrestrial C pool. Nonetheless, we lack a basic understanding of what controls immobilization...
