The effect of physical and hydraulic properties of peat moss and pumice on Douglas-fir bark based soil-less substrates

Creator:: Zazirska Gabriel, Magdalena
Abstract:: Douglas-fir [Pseudotsuga menziesii (Mirbel) Franco] bark (DFB), sphagnum peat moss, and pumice are the most common substrate components used in the Oregon nursery industry. Despite the widespread use of these three components, little information is available on the effect of physical and hydraulic properties of peat moss and pumice on...

Cultural controls for suppressing Phytophthora cinnamomi root rot of blueberry

Creator:: Yeo, John R.
Abstract:: Phytophthora cinnamomi is a soilborne pathogen that causes root rot disease of highbush blueberry (Vaccinium corymbosum L.). When new installations of susceptible blueberry cultivars are infected with P. cinnamomi, plants often fail to grow significant new tissue, greatly reducing yields over the life of the planting. Chemical fungicides are available...

Soil quality dynamics in an integrated reduced-tillage and cover-cropped vegetable agroecosystem

Creator:: Banners, Candace R.
Abstract:: Soil response and function were investigated following the adoption of an integrated reduced-tillage and cover-cropped vegetable system in the Willamette Valley of Western Oregon. The experiment was conducted over three cropping seasons (2002-2004) at the Oregon State University Vegetable Research Farm (Corvallis, OR). The design was a randomized complete-block with...

Maturity and stability evaluation of composted yard debris

Creator:: Brewer, Linda J.
Abstract:: Compost maturity is an important determinant of end use for composted municipal yard debris, and generally refers to the effect the compost has on plants. The rate of microbial respiration is an indicator of compost stability. The objectives of this research were to: i) determine whether continuous aeration resulted in...

Assessment of Feedstock Materials for Producing a Suitable and Cost-Effective Biochar to Use as a Soil Amendment for Northern Highbush Blueberry (Vaccinium corymbosum)

Creator:: Kumari, Pooja
Abstract:: Biochar is a highly porous, carbon-rich residue produced by thermochemical conversion (pyrolysis) of plant biomass and carbonaceous organic materials under oxygen-controlled conditions. Chars produced by this process tend to have high ion-exchange capacities and, when added to soil, increase retention of water and nutrients and improve soil aggregation, porosity, and...

Impact of a red clover winter cover crop on carbon and nitrogen mineralization by microorganisms in soil aggregates

Creator:: Ndiaye, Aissatou
Abstract:: Although legumes have been widely studied for their nitrogen-fixing ability, it is uncertain to what extent legume cover crops achieve their nitrogen-fixing potential under the climatic conditions encountered in western Oregon. Furthermore, it is unknown what factors control the proportions of legume cover crop N that are either sequestered into...

Suitability of diverse composts as soil amendments for highbush blueberry (Vaccinium corymbosum L.)

Creator:: Costello, Ryan C.
Abstract:: Highbush blueberry (Vaccinium corymbosum L.) is adapted to soils with high organic matter and acidic pH. Composts provide organic matter and nutrients for growing blueberry in mineral soils, but many composts are high in pH and soluble salts. Acidification with elemental sulfur (S°) can remedy high pH, but the process...

Estimating plant-available nitrogen release from manures, composts, and crop residues

Creator:: Gale, Eric S.
Abstract:: In order to properly utilize organic amendments as nitrogen sources, reliable methods to estimate plant-available nitrogen (PAN) are needed. The objectives of this study were to (1) evaluate the use of crop and soil responses in fertilizer N equivalence (FNE) calculations, (2) examine the relationships between the C/N ratio, total...
