1. Evaluation of Soil Test Methods and Crop Response to Phosphorus Fertilization in KansasWheat (Triticum aestivum) is typically considered the most responsive crop to phosphorus (P) fertilization in Kansas. This study was conducted to evaluate wheat response to P fertilization using modern genotypes and soil test calibration/interpretation for Kansas soils. The study was conducted during the 2018-2019 growing season with eleven locations in Kansas. Randomized complete block design was used for four differe... C. Weber, D.A. Ruiz diaz |
2. Evaluating Relationships between Soil Respiration and Nitrogen Use Efficiency in CornAvailable 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 |
3. Managing Nitrogen to Optimize Yield and Quality of North Dakota Two-row Malting BarleyAs the demand of two-row malting barley (Hordeum vulgare L.) increases, having sound N recommendations is increasingly necessary. Not only does N play a role in grain yield, but it may also significantly impact grain malting characteristics including protein, plump, and test weight. To determine the impacts N rate and N availability have on two-row malting barley, two experimental sites were established in both Spring 2020 and 2021. The experiment was organized in a randomized comple... B. Goettl, H. Bu, A. Wick, D. Franzen |
4. Can Soil Health Metrics Improve Standard Soil Fertility Recommendations?It is commonly speculated that integrating soil health (SH) testing with soil fertility (SF) testing would improve fertilizer recommendation decisions. However, quantified impacts of SH properties, specifically soil biological properties, on fertilizer demand have not been well established. The objective of this research was to explore corn (Zea mays L.) yield response to phosphorus (P) and potassium (K) fertilization as influenced by established SF analysis and common SH me... C.J.
