Soil Solarization in Pacific Northwest Tree Seedling Nurseries: Effects on Soilborne Plant Pathogens, Soil Nutrients and the Soil Microbiome

Creator:: Weidman, Clara S.
Abstract:: Nursery and greenhouse products are economically important agricultural commodities for Oregon and Washington. Nursery crops including tree seedlings can be damaged or killed by soilborne plant pathogens, which can be challenging to manage because of their persistence in soil and limited options for control. Soil solarization is a pre-planting soil...

Solarization in the Pacific Northwest: A Mathematical Field Model for Accumulation of Linearized Mortality from Variable Intermittent Heat

Creator:: Hill, Brian C.
Abstract:: Soil solarization trials were conducted during the growing seasons of 2016-2018 with the purpose of determining if solarization was an effective pre-planting soil disinfestation technique for tree nurseries in the Pacific Northwest. A large data set was collected on soil properties and biological indicators from 5 interdisciplinary experiments. This thesis...

Soil solarization at an organic farm: effects on weed emergence, soil nutrients and soil microbial communities

Creator:: Trammell, Caleb, Eberhart, Joyce, and Parke, Jennifer L.
Abstract:: Weed management is one of the main challenges for organic agriculture. Soil solarization has been shown to be an effective mitigation strategy for weeds and soil borne plant pathogens but few studies have been conducted in cooler climates such as the Pacific Northwest.

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...

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...

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...
