Elicitors: A Novel Tool for Controlling the Colorado Potato Beetle Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae)

Creator:: Butcher, Alexander M.
Abstract:: Over the last several decades, potato production has increased globally as it has been recognized as an important component to improving food security. However, potato production has been continuously challenged by pests. Current pest management practices rely heavily on chemical pesticides. Unfortunately, the overuse of pesticides can be harmful to...

Excel worksheet for calculating agronomic biosolids application rates

Creator:: Sullivan, Dan M.
Abstract:: The worksheet is designed to show a municipal biosolids manager how many acres are needed for land application of biosolids at an agronomic rate, based on crop nitrogen (N) requirements. The worksheet is based on a peer-reviewed Extension publication: PNW 511, Worksheet for Calculating Biosolids Application Rates in Agriculture authored...

Olives in Oregon: Grower Survey, On-Farm Propagation, and Orchard Establishment in a Non-Traditional Growing Region

Creator:: Barker, Tessa A.
Abstract:: Olive production potential in Oregon was researched in a multi-disciplinary approach, including a grower survey, a propagation greenhouse study, and a field study, from 2018 through 2020. The Oregon Olive Grower Survey was designed to collect information relating to orchard establishment and management practices, knowledge and understanding of these practices,...

Measuring ammonia loss using field-scale and laboratory techniques

Creator:: Heinrich, Aaron and Sullivan, Dan M.
Abstract:: Following the surface application of urea to soil, there is the potential for nitrogen (N) loss from ammonia (NH3) volatilization until sufficient rain or irrigation has moved it into the soil. Many studies measuring NH3 loss have used laboratory and microplot field studies. The limitation of these techniques is that...

Agronomic biosolids application rates for dryland wheat across a range of northwest climate zones

Creator:: Sullivan, Dan M., Bary, Andrew I., Cogger, Craig G., and Shearin, Todd E.
Abstract:: Predicting agronomic rates is important to derive optimum economic and environmental benefits from biosolids fertilizer applications. We conducted this research to 1) evaluate dryland wheat response to biosolids applications over a range of climate zones in the Pacific Northwest and 2) compare agronomic application rates predicted from yield curves with...

Invertebrates (except family Carabidae) caught by pitfall and refuge trap sampling in Linn Co March 2018-June 2019

Creator:: Reich, Inga, Jessie, Casi, Gormally, Mike, and McDonnell, Rory
Abstract:: Numbers of invertebrates (except family Carabidae) collected from pitfall and refuge traps in ten Annual Ryegrass fields in Linn County, Oregon between March 23, 2018 and June 20, 2019. Given are details on sampling date, site and trap ID, trap type, taxonomy (at least order level) and life stage.

Soil and plant test calibration to improve nutrient management

Creator:: Cogger, Craig G., Bary, Andrew I., Cramer, T. N., and Grusenmeyer, D. C.
Abstract:: Addendum to final report, Abbotsford-Sumas Aquifer Nitrate Management Project G9500254.
Resource Type:: Technical Report

Field microplot estimates of soil N mineralization for manured and non-manured soils

Creator:: Sullivan, Dan M., Cogger, Craig G., Bary, Andrew I., and Myhre, Elizabeth
Abstract:: Credits for available N from past manure applications are often used in nutrient management planning. However, it is difficult to verify the accuracy of these credits. The major objective of this study was to estimate long-term effects of manure application on soil N mineralization. Specific objectives were to: 1) estimate...

Pitfall and refuge trap sampling Linn Co March 2018-June2019

Creator:: Reich, Inga, Jessie, Casi, Ahn, Seung-Joon, Choi, Man-Yeon, Williams, Christopher, Gormally, Mike, and Mc Donnell, Rory
Abstract:: Numbers of carabid beetles, caterpillars, cranefly larvae and slugs collected from pitfall and refuge traps in ten Annual Ryegrass fields in Linn County, Oregon between March 23, 2018 and June 20, 2019. Given are details on sampling date, trap, size and sex (carabids only), weight (slugs only) and species (where...
