Monitoring soil nitrate to estimate cover crop nitrogen contribution in organic vegetable production fields

Creator:: Andrews, Nicholas, Sullivan, Dan M., and Pool, Kristin
Abstract:: Organic vegetable growers rely on legume cover crops as an economical source of plant-available N. This research evaluated N contributions to summer vegetable crops by cover crops (CC) residues by monitoring soil nitrate (NO3-N) concentrations during the summer crop growing season. Replicated field plots were established with three CC mixes:...

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...

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...

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...

Improving fertilizer P and N use efficiency in sweet corn : 2013 Research report to the Oregon Processed Vegetable Commission

Creator:: Heinrich, Aaron, Sullivan, Dan M., and Peachey, Ed
Abstract:: The enhanced efficiency (EEF) products we tested in our study hold the potential to increase the nitrogen utilization efficiency of sweet corn as well as reduce nitrate leaching when all N fertilizer is applied before planting. However, this potential is limited by weather (i.e. large early season rainfall events), irrigation...

Enhanced efficiency fertilizer technologies for improved production in sweet corn (2015) : Oregon Processed Vegetable Commission Final Project Report

Creator:: Sullivan, Dan M., Heinrich, Aaron, and Peachey, Ed
Abstract:: Urea is a common nitrogen fertilizer for sweet corn production. This two year project evaluated commercially available urea additives for their potential to provide crop production and environmental benefits. Specifically, experiments were designed to evaluate the efficacy of urea fertilizer products containing a urease inhibitor (Agrotain Ultra), or nitrification inhibitors,...

Enhanced efficiency fertilizer technologies for improved production in sweet corn (2014) : Oregon Processed Vegetable Commission Continuing Project Report

Creator:: Sullivan, Dan M., Heinrich, Aaron, and Peachey, Ed
Abstract:: Enhanced efficiency fertilizer (EEF) technologies have the potential to improve the crop N use efficiency (NUE) as well as minimize negative environmental losses compared to conventional fertilizers. The EEF fertilizer products consist of urea plus additives (to inhibit N loss). The major pathways for N loss in our sweet corn...
