1. Beyond the Acre Furrow Slice: a New Era in Nutrient ManagementThe Midwest faces a pivotal shift in how we develop nutrient guidance for farmers. The long-running “build-up and maintenance” approach, built on decades-old soil-test methods, no longer aligns with today’s diverse and dynamic farming systems. Instead of anchoring decisions to soil depths tied to historical moldboard plow use, we should emphasize soil supply and plant uptake over time. Recommendations must be grounded in actual nutrient removal at harvest, on a site-by-site... H.M. Brown |
2. The Effects of Phosphorus and Potassium Application on a 14-year-old Miscanthus × giganteus StandMiscanthus × giganteus (miscanthus) is a perennial C4 grass grown for renewable bioenergy and bioproducts. While miscanthus is often considered to have low nutrient requirements, the need for fertilization remains poorly understood, particularly in mature stands. This study aims to provide insight by evaluating for potential phosphorus (P) and potassium (K) limitations in a 14-year-old miscanthus stand in central Iowa that had received no prior fertilization. The experiment followed... J. Studt, A. Larson, A. Vanloocke, M. Mcdaniel, E. Heaton, N. Boersma |
3. Technology, Innovation, and the Future of Soil FertilityThis panel will focused on how technology is being used in the practice of soil fertility and nutrient management. Panelists will also discuss how they’ve incorporated new and old soil fertility concepts into their approach to guiding fertilizer use. Lastly, we will discuss where soil fertility is going as a scientific discipline. ... H.M. Brown, W. Berg, R. Mullen |
