1. Canola Roots of Water and Nitrogen Use Efficiency: New Lessons for PNW Wheat GrowersThe semi-arid inland Pacific Northwest (iPNW) has primarily produced wheat for 125 years due to favorable climate, soils, economics and policy drivers. Shifting drivers over the past decade related to energy, climate change, regional and global markets have created new opportunities for the integration of canola into iPNW wheat-dominated rotations. Traditional wheat grower mindsets required an agronomic reboot, forged by an understanding of canola vs. wheat physio morphology, an explosion of variety... W. Pan, T. Maaz, I. Madsen, W. Hammac, M.

2. Nitrogen Management in WheatYields for current wheat varieties are quickly approaching 200 bu/a in high yielding environments. There are many approaches to managing nitrogen in wheat production systems using a variety of products on the market today. Urea, ESN, Agrotain, Arborite, DCD and many other nitrogen products are available for making sound agronomic decisions. Once the wheat plant is grown at about Fekes 7.0 there is the quandary of making protein when hard red winters or DNS types are grown. Choices become endless... D. Howneck |
3. Micro-nutrients in Alfalfa Production: is There Need/opportunity for Cost Effective Management?The management of soil fertility for optimum alfalfa productivity requires that all nutrient-related limitations be manipulated where warranted and cost-effective. It has been the policy of the Utah State University Analytical Laboratory to not promote soil testing for micronutrient sufficiency based on a lack of general need, historically, for nutrients such as sulfur, boron, zinc and others. This study undertook to accomplish two things, 1) to provide an initial inventory of micronutrient... G. Cardon, J. Barnhill, M. Pace, C. Israelsen, D. Miner, L. Greenhalgh, S. Banks, M. Shao, D.

4. The Effects of Calcium Source and Placement on Soil Factors and Wheat Performace FactorsWheat production is a critical component of U.S. Pacific Northwest agriculture, with approximately 80% of the global soft white wheat grain supply originating from this region. Ammonium-based nitrogen fertilizers are widely used on typically alkaline soils in Eastern Oregon dryland production areas by wheat growers. However the nitrification process that biologically converts ammonium to nitrate increases the soil concentration of H+. This process ultimately creates acidic soil conditions, which... S.
