1. Nitrate Leaching Characteristics for Various Nitrogen Management Strategies on Irrigated CornEfficient use of nitrogen (N) fertilizer for corn production is important for maximizing economic return to the producer and minimizing NO3 leaching to groundwater. This is especially important on irrigated, sandy soils due to the high infiltration and saturated conductivity and potential risk to the local water supplies. This study is being conducted to quantifL the NO3 leaching potential in the irrigated sands along Kansas' waterways under current and alternative N and water management strategies... |
2. Side-dressing Nitrogen Influence on Nitrogen Release Dynamics of Early and Late-Terminated Cereal Cover CropTermination date and nitrogen application of corn (Zea mays L.) can influence the decomposition rate of cover crops in a corn cropping system. Our objective was to evaluate (i) the biomass accumulation and nutrient uptake of wheat (Triticum aestivum L.) fertilized with 34 kg N/ha and (ii) decomposition rate of wheat terminated early (4 weeks prior to planting) and late (at corn planting time) with and without side-dressing N at 168 kg N/ha. Our preliminary data... A. Sadeghpour, G. Singh, A. Weidhuner, R. Lange |
3. Banding Nitrogen Increases Nutrient Uptake and Yield of CornInadequate nitrogen (N) availability during the start of the corn (Zea mays L.) growing season can reduce the yield potential of the crop. However, the greatest amount of N is required during the period of rapid growth (from 10-leaf stage to tasseling [VT]). Banding N at or near the time of panting increases availability of N to the corn plant and could allow for the reduction in early-season N rates without reducing yield potential. Across the state of Illinois in 2019, urea ammonium nitrate... E.T. Winans, F.E. Below |
