1. Evaluating Relationships between Soil Respiration and Nitrogen Use Efficiency in Corn Available nitrogen (N) often limits the agricultural production of corn (Zea mays) and the N fertilizer use efficiency is of primary concern for producers in Kansas and the Midwest. This study was carried out to understand the agronomic value of commercially available soil health tests (e.g. 24 hr CO2 burst) and their relationship to components of nitrogen use efficiency (NUE) in corn. Relationships between N response and soil CO2 evolution were investigated across multiple sites and manageme... D. Ruiz diaz, B. Rutter
2. NITROGEN CREDIT FOR LONG-TERM NO-TILL CROP PRODUCTION IN NORTH DAKOTA Feedback from farmers who had been in no-till crop production for over twenty years indicated that crop production could be maintained at high levels with a reduction in N rate from the universally recommended rates. Nitrogen rate studies in spring wheat/durum, corn and sunflower have confirmed that N rates can be reduced when a farm is under continuous long-term no-till production. A portion of the N credit may be uptake of N by microorganisms, thereby reducing the amount of N exposed to lea... D. Franzen Download paper
3. Understanding Spatial Variability in Cover Crop Growth and Decomposition In many agricultural landscapes, topographic variability leads to downslope movement of soil, water, and nutrients, causing heterogeneity in both crop yield and soil fertility throughout production fields. Cover crops can slow these processes, but the impact of topography on cover crop growth and residue persistence is uncertain. We measured the growth, mixture biomass composition, and decomposition of a cereal rye (Secale cereale L.) cover crop, and cereal rye /crimson clover (T... S.J. Leuthold, M. Salmeron, O. Wendroth, E.
