1. Wastewater Reuse in the Arid West: Increased Water Supplies and New Paradigms for Nutrient Management Irrigated agriculture in the western United States is one of the most productive systems in the world. However, in recent years the security of water supplies for agriculture have come into question. Currently states that use Colorado Riverwater are in the process of formalizing drought contingency plans to prevent reservoirs along the Colorado River from going dry. Competition for water with the agricultural sector include both urban and environmental uses. Treated municipal effluent... C. Williams
2. Soil Water and Plant Canopy Sensor Technologies to Optimize Water and Nutrient Use In many respects, agricultural technology is doing things now that were only imagined 20 to 30 years ago. Yet, grower tools that provide information and actionable knowledge on water and nutrient availability still remain a challenge. Clearly, rapid development of data transfer and processing platforms to date has provided rich maps of grower fields with overlays of location-specific information but their utility is still limited by our ability to accurately measure the parameters that are the...

3. Nitrous Oxide Emissions: Assessment and Mitigation in Irrigated Cotton in the Western USA Nitrogen from fertilizers is a major source of the potent greenhouse gas nitrous oxide (N2O) in irrigated cropping systems. To date, N2O emission data is scarce for row crops in the Western USA, especially, the desert southwest, where seasonal irrigation quantities can exceed 40 inches. The objective of these studies was to assess the effect of N fertilizer management on N2O emissions from furrow-, overhead sprinkler-, and subsurface drip-irrigated (SDI) cotton (Gossypium hirsutum L.) in...

4. Soil Copper Thresholds for Potato Production A rising concern with the application of dairy wastes to agricultural fields is the accumulation of copper (Cu) in the soil. Copper sulfate (CuSO4) from cattle footbaths is washed out of dairy barns and into wastewater lagoons. The addition of CuSO4 baths on dairies can increase Cu concentration significantly in manure slurry. The Cu-enriched dairy waste is then applied to agricultural crops, thus raising concerns about how soils and plants are impacted by these Cu additions. Repeated applications... A. Moore, M.

5. 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
