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...

Preplant compost application improves landscape plant establishment and sequesters carbon in compacted soil

Creator:: Sullivan, Dan M.
Abstract:: Preplant compost application increased plant growth and visual appearance of a wide variety of perennial landscape plants. The positive plant growth response to compost was similar for com-post left on the soil surface or compost incorporated via rototilling. Compost application did not alleviate soil compaction. Plant growth response to compost...

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...

Estimating in-situ N mineralization rate with a buried bag method

Creator:: Sullivan, Dan M. and Moore, Amber D.
Abstract:: Accurate estimates of soil nitrogen (N) mineralization rate and timing are needed for refining N management practices. This paper describes a buried bag method that has been successfully included within agronomic field trials in the Pacific Northwest, USA. We have found this method to be technically simple and reproducible, and...

Refining nitrogen management for organic broccoli production

Creator:: Sullivan, Dan M., Peachey, Ed, and Donaldson, Andrew
Abstract:: Specialty organic fertilizers used in organic vegetable production are expensive. So, from environmental and economic perspectives, growers want to maximize nitrogen (N) fertilizer use efficiency by the crop. This research was conducted to (1) determine sufficient N fertilizer rates for organic broccoli, (2) evaluate the efficacy of a specialty organic...

Municipal composts improve landscape plant establishment in compacted soil

Creator:: Sullivan, Dan M., Bell, Neil, Owen, Jim, Kowalski, Judy, and McQueen, John
Abstract:: Urban landscape soils are often compacted by construction activities, thereby restricting plant establishment. Common approaches to improve plant establishment on compacted soils are to till soil before plant installation, to apply compost, or to choose plants that can tolerate drought. This research was undertaken to evaluate the relative importance of...

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...
