1. Effects of Commercial Organic and Cyanobacterial Fertilizers on Instantaneous Water Use Efficiency in Drip Irrigated Organic Sweet Corn Water and fertilizers are applied to maintain crop growth, yield, and quality. Nitrogen (N) fertilizer plays a crucial role in crop growth and yield development of sweet corn (Zea mays). Organic growers often use commercial organic animal- based fertilizers which vary in nutrient composition, forms of available N (NH4+- N and NO3--N), and have high transportation costs. Alternatively, cyanobacteria can be grown on-site as a source of N. Cyanobacteria haves unique dual properties because they... J. G. davis, A. Sukor, C. Ramsey Download paper
2. Phosphorus and Organic Acid Bonding Enhances Uptake Efficiency in Crop Plants Phosphorus (P) fertilizer is essential for crop production, but reductions are warranted to conserve resources and minimize environmental impacts. Several lab, glasshouse, growth chamber, and field studies have been performed over the past five years with a new P fertilizer (Carbond P; CBP; Land View Fertilizer, Rupert, ID, USA) in calcareous, low OM soil. This presentation will be a review of that data. Studies comparing CBP to ammonium polyphosphate (APP) applied to soil show season-long increases... B. Hopkins, T. Blair, M. Hill, C.

3. Waxy Barley: N Applications for Yield, Beta-glucan, and Protein Nitrogen fertilizer (N) management was evaluated for growing irrigated waxy barley for higher protein and beta-glucan soluble fiber content. A local company has proposed the building of a barley fractionation plant to capitalize on these value-added traits. Salute and Merlin, two spring waxy barley cultivars, were fall-planted to compare yield and quality under different N treatments applied in late winter and at heading and to evaluate ethephon to reduce lodging. Fairly normal winter weather... S. Norberg, B. Brown, C. Shock, A. Ross, P. Hayes, J. Rey
4. Speculation on an Equation for Stratification: How Reliably Can We Estimate Soil Test Values at Different Depths? The depth to which soil is sampled in a field impacts measured soil test values. However, across the West, depth of soil sampling can vary by state, region and cropping system. What if we're interested in comparing crop responses to fertilizer application across a large scale? How do we reconcile trials that are sampled at different soil depths? This study was part of the Fertilizer Recommendation Support Tool (FRST) project, with the goal to develop equations that allowed comparison... S. Culman
