1. Comparison of Induced Sludge Bed (Blanket) Anaerobic Reactor to Vertical Plug Flow Technology for Animal Manure Digestion1 The 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 Download paper
2. Nebraska Nitrogen Management Present and Future University of Nebraska faculty have been refining their N rate recommendation procedure since the 1970s. At that time, they introduced a procedure for predicting soil nitrate-N availability and effect on subsequent corn N needs. In the 1990’s this procedure was refined based on 81 state wide N rate experiments. In 2003-2006 it was re-confirmed with 32 state wide irrigated corn trials. The current algorithm is the following: N need (lb/ac) = [35 + (1.2 x EY) - (8 x NO3- N ppm) - (0.14 x EY... C. Shapiro, R. Ferguson, C. Wortmann, T. Shaver, B. Krienke, G. Hergert, B.

3. On-Farm Variable-Rate Nitrogen Management in Potato Applying variable nitrogen (N) has often improved yields, quality, and/or N use efficiency (NUE) of several crops. The objective of this study was to evaluate how pre-emergence variable rate N (VRN) zones vs. uniform N management impacts potato (Solanum tuberosum L.) yield, quality, and NUE. Low, average, and high N zones were created and evaluated for 10 site-years at fields near Grace, Idaho, USA over two years with rates based upon yield goals, soil, water, and previous crop information....
