1. Banded Fertility: Music for Higher Corn Yields There is a need in production agriculture to reduce nutrient loss to the environment and implement more sustainable production practices, but grower adoption has been slow and inconsistent due to fear of reduced yields and profit. However, if new fertilizer technologies can be used to increase nutrient use efficiency and grain yield simultaneously, grower willingness to adapt environmentally sustainable practices is far more likely. We implemented a two-year corn (Zea mays L.) yield ... S. Foxhoven, F. Below Download paper
2. Comparative Effects of Herbicide, Nitrogen Inhibitors and Nitrogen Source on Nitrification and Corn Yield Nitrogen management in crops can be challenging due to nitrogen transformations and losses in soil, such as nitrification and denitrification. Nitrification is the conversion of ammonium (NH4+) to nitrate (NO3-) by ammonia oxidizing bacteria (AOB), Nitrosomonas and Nitrobacter. Nitrates can be lost through leaching during heavy precipitation. Nitrification inhibitor products are used to temporarily slow the nitrification process by... W. Neels, A. Jhala, B. Maharjan, R. Little, J. Iqbal Download paper
3. Comparison of Mehlich-3 and Haney H3A-4 Soil Tests in Kansas Soils Recommended application rates of soil fertility amendments are often based on a soil test in agricultural production systems. Interpretation of these soil tests requires correlation and calibration to crop yield response, nutrient uptake, or existing soil tests. The Mehlich-3 soil test procedure is currently used to evaluate the plant availability of phosphorus (P) and potassium (K) in Kansas soils. However, the Haney soil test has gained attention in recentyear and has been used to adjust so... B. Rutter, D. Ruiz Diaz Download paper
4. Corn Response to Phosphorus Fertilization and Evaluation of Soil Test Methods in Kansas Soils Phosphorus is a critical nutrient in corn (Zea mays L.) production, and limitation in P availability can result in significant yield reduction. The objective of this study was to evaluate corn response to phosphorus fertilization and evaluate multiple soil test methods in Kansas soils. The study was conducted in 13 locations across Kansas during 2021. Fertilizer treatment consisted of five rates of phosphorus (P) fertilizer (0, 30, 60, 90, and 120 lbs. P2O5 acre–1), using mono-...

5. Evaluation of Soil Test Methods and Early Tissue Analysis to Assess Potassium Response in Soybean Multiple soil test methods has been evaluated as diagnostic tool for potassium management in soybeans. This study compared different soil test K methods (STK) and evaluate the correlation to soybean yield and K uptake response in low testing soils, and assessed tissue analysis as alternative for in-season correction options. ...

6. Grain Yield and Nutrient Removal Relationships in High-yield Modern Corn Hybrids Under In-season Sulfur and Potassium Applications Advancements in modern corn genetics and adoption of intensive management practices, including in-season sulfur (S) and potassium (K) applications, have helped corn farmers set higher yield goals while prompting new questions about plant nutrient dynamics during the season and cumulative nutrient removal with grain at harvest. The primary goal of this study was to investigate how hybrid and fertility management decisions in situations with high yield potential (>225 bushels acre-1) impact ... G. Verhagen, T. Vyn Download paper
7. Soil Mineral Nitrogen Response to Nitrogen Fertilizer Application in Corn Early Growth Season Soil Mineral Nitrogen (SMN) plays a crucial role for the growth and productivity of crops such as corn, this crop is very demanding of nitrogen (N) in early growth stages. Maintaining the highest amount of N in the form of ammonium (NH4+) or nitrate (NO3-) can be key to obtaining high yields. Substances such as nitrification inhibitors (NI) were created to avoid losses of N from the soil. This study was carried out in 8 site year loca... P. Morinigo, D. Ruiz Diaz Download paper
8. The Nitrate Soil Test in South Dakota The nitrate nitrogen soil test has been used for more than 15 years for making nitrogen fertilizer recommendations in South Dakota. Minimal leaching and denitrification due to a relatively dry climate has helped make this test a good predictor of nitrogen fertilizer needs. The test and nitrogen recommendation system is based on a two foot deep soil sample and a calibrated nitrogen requirement for common crops grown in South Dakota (Table 1). Extensive field plot data shows that the two foot deep... Download paper
