1. Soil N2O emissions in continuous corn as affected by 4R and cover cropsCover crops and 4R nitrogen (N) management are promoted as key practices for reducing nitrate leaching losses, but their impacts on nitrous oxide (N2O) emissions remain less certain. This study evaluated soil N2O emissions and grain yield under different timing of N application and cover crops for two years in a tile-drained continuous corn system. Treatments were 224 kg N ha-1 split-applied in fall + pre-plant (Conventional), pre-plant + side-dress (4R), 4R +... G. Preza Fontes, L.E. Christianson, C.M. Pittelkow |
2. Enhancing Nitrogen Fertilizer Efficiency in Sorghum to Boost Yields and Reduced Nitrogen LossNitrogen management is crucial in modern farming as it plays a major role in achieving higher yields. This study aimed to identify the optimal nitrogen application rate and best management practices to prevent over-application, nitrogen losses, and nitrogen deficiency in crops. Kansas, a leading state in sorghum production, served as the study's setting. Research was conducted at four sites during 2021 and 2022 on rain-fed fields in North-East and North-West Kansas. The objectives... M. Platero, P. Morinigo Ferreira, D. Ruiz Diaz, P. Tomlinson |
