1. Comparison of Induced Sludge Bed (Blanket) Anaerobic Reactor to Vertical Plug Flow Technology for Animal Manure Digestion1The purpose of this study was to compare Induced Sludge Bed Anaerobic Reactor (IBR) (Hansen, Hansen, 2005) animal manure digestion technology to Vertical Plug Flow (VPF). In 2008 an IBR system at Sunderland Dairy Farm in Chester, Utah was repaired and retrofitted by Utah State University (USU), Extension, Utah Science, Technology and Research Initiative (USTAR), and Sunderland Dairy Farm. This was the first time research has compared IBR and VPF digester performance at a single site in a side-by-side... J. Gale, P. Zemke, B. Wood, S. Sunderland, S. Weeks |
2. Science and Stakeholder Engagement on 4R Nutrient Stewardship, Sustainability and Nutrient Performance Indicators: a Recent Central to Eastern U.S. and Global PerspectiveFarmers and society are becoming more aware of the need to better protect water, air and soil resources. The focus of the International Plant Nutrition Institute (IPNI) is on responsible nutrient management and stewardship to support the needs of the growing human family. Since 2007, IPNI has been more actively engaged with university scientists, federal and state agencies, agribusiness associations, crop advisers, and nongovernmental partners to get more of the applied nutrients - especially...

3. Biosolids-based Fertilizers as a Nitrogen Source in California Small Grains SystemsSituation/ conditions In response to regulatory and economic pressure, California growers are becoming more familiar with nitrogen budgets. In addition to seeking out ways to improve nitrogen management strategies, growers can possibly benefit by incorporating alternative sources of nitrogen to feed their crops. Liquid injected or pelletized biosolids-based fertilizers from local waste streams and processing facilities are one source that growers are beginning to explore. As... K. Mathesius, D. Geisseler, M.
