Costs of Establishing Organic Northern Highbush Blueberry: Impacts of Planting Method, Fertilization, and Mulch Type

Creator:: Julian, James W., Strik, Bernadine C., Larco, Handell O., Bryla, David R., and Sullivan, Dan M.
Abstract:: A systems trial was established to evaluate factorial management practices for organic production of northern highbush blueberry (Vaccinium corymbosum L.). The practices included: flat and raised planting beds; feather meal and fish emulsion fertilizer applied at 29 and 57 kg·ha⁻¹of nitrogen (N); sawdust mulch, compost topped with sawdust mulch (compost...

Increasing liming efficiency on processed vegetable farms (2016) : Oregon Processed Vegetable Commission Final Project Report

Creator:: Sullivan, Dan M. and Heinrich, Aaron
Abstract:: Several new powdered limestone products that are more finely ground (smaller particle size distribution) than products historically used have become commercially available. A major factor influencing the effectiveness of a liming material is its particle size distribution, with smaller particles reacting more quickly. Because lime efficiency estimates for various particle...

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...

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...

Interseeding of Cover Crops to Improve Cover Crop Establishment and Performance : Oregon Processed Vegetable Commission Project Report, 2015

Creator:: Peachey, Ed and Sullivan, Dan M.
Abstract:: This project is evaluating interseeding of crop crops to improve cover crop establishment after late harvested crops such as sweet corn and processing squash. In Project 1 at the OSU Vegetable Research Farm, a cover crop of oat and crimson clover produced the most cover crop biomass when interseeded at...

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...

Providing organic nutrient management guidance to processed vegetable growers : Oregon Processed Vegetable Commission Continuing Project Report, 2016

Creator:: Sullivan, Dan M. and Heinrich, Aaron
Abstract:: The market for organic vegetables is increasing. As conventional farmers transition fields to organics to meet this demand, there is a need for better organic nutrient management guidance, especially for nitrogen (N). Organic N management is more challenging than conventional N management due to a higher level of uncertainty surrounding...

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...

Effect of pop-up fertilizers and planting density on early season sweet corn growth and ear yield : Oregon Processed Vegetable Commission Continuing Project Report, 2014

Creator:: Peachey, Ed and Sullivan, Dan M.
Abstract:: Prices paid for sweet corn are low relative to the cost of producing the crop, and every strategy possible must be used to maximize net return. Two strategies used to enhance profitability but that have received little research attention under Western Oregon conditions are the use of pop-up fertilizers and...
