1. Residual Effects of Nitrogen Fertilization on Soil Nitrogen Pools and Corn GrowthNitrogen (N) fertilization of corn (Zea mays L.) may increase, decrease, or not affect the N supplying capacity of the soil. Six field-scale corn N rate trials were established in corn-soybean rotations in diverse soil types across Indiana. Six N rates ranging from about 25 to 270 lb N ac-1 were replicated 4 to 6 times at each site and re-applied to the same plots for each of four corn crops. In the fifth corn season, 2015, half of the replications at each location were supplied... M. Moser, R. Nielsen, J. Camberato |
2. Optimum N Rates for Corn Production as Influenced by Crop RotataionFertilizer N efficiency in corn production has become a'hot' research topic in the 1980's. Increased concerns of nitrate-N entering the groundwater and the potential for improving the profitability of corn producers are the impetus for fine-tuning fertilizer N recarmnendations. Crop production factors such as improved diagnostic techniques, full utilization of symbiotic N fixation, and crop rotation have been gaining widespread research support throughout the United States. The adoption of crop rotations... |
3. Nitrogen Fertilizer Rates and Nitrification Inhibitor Impact Agronomic and Economic Returns in Corn Production in KansasNitrogen (N) is an essential nutrient for corn crop, higher grain yields are related to N fertilizer application. Substances like the nitrification inhibitors (NI) were created to increase yields, promote Nitrogen Use Efficiency (NUE), and reduce N losses. The study was carried out in ten site-years in Kansas during 2017, 2018, 2019, 2020 and 2021 crop seasons, with the objective of evaluate the Nitrogen Agronomic Efficiency (NAE) in corn with and without the use of NI and to compare corn grain...
