1. Corn Hybrid Responses to Nitrogen Fertilizer RatesEfficient use of nitrogen (N) fertilizer is becoming increasingly important in modem corn (Zea mays L.) production due to rising nitrogen fertilizer prices and growing concerns about NO3- contamination of ground and surface waters. Interest has arisen in whether nitrogen management can be improved by choosing hybrids that respond better to nitrogen. In order to see if hybrids respond differently to varying rates of N fertilizer, we grew nine hybrids at five N rates for three years at Urbana: Illinois.... |
2. The Use of Organic Soil Amendments for Winter Wheat Production in KentuckyMost animal manures are land-applied in the fall and spring after crops have been harvested or prior to planting. Surface application of manures in the fall have more potential for nitrogen (N) loss when applied to fallow land compared to land cropped to winter wheat. This study was conducted to determine the N availability of fall applied organic fertilizers and resulting wheat grain yields compared to urea-N fertilizer. The effects of three organic fertilizer sources and rate on wheat yield and... |
3. The Future of Soil Fertility - My Two CentsThis presentation will provide information of what a large cooperative is currently providing customers in the realm of nutrient management. Additionally, some insight will be provided on how other aspects of nutrient management (global markets, production technologies, etc) are being evaluated. Finally, some general ideas will be shared regarding the future needs of the retail sector along with some research ideas. ... R. Mullen |
4. Technology, Innovation, and the Future of Soil FertilityThis panel will focused on how technology is being used in the practice of soil fertility and nutrient management. Panelists will also discuss how they’ve incorporated new and old soil fertility concepts into their approach to guiding fertilizer use. Lastly, we will discuss where soil fertility is going as a scientific discipline. ... H.M. Brown, W. Berg, R. Mullen |
