A comprehensive monitoring system for quantifying direct and indirect sources of N2O emissions will be applied within currently existing field experimental studies at multiple contrasting site locations where specific practices for reducing total N2O emissions will be compared with conventional management. Use of the same measurement methods across all sites will increase the validity of the data. A key aim of the project is to disseminate practical information to agricultural producers, industry, conservation officials and others who will ultimately benefit from the research. Technology transfer will be expedited by University of Minnesota professors with substantial experience in Extension service and collaboration with farmers and commodity groups. To assist in the development of information products described below and to identify other potential issues to be addressed, a survey of current N management practices and information needs among agricultural producers across the state of Minnesota will be conducted. University of Minnesota Extension Service personnel with expertise in surveys will design and conduct the survey. The survey will help to identify potential users of the information, to generate mailing lists, and to assess preferences for web-based versus printed material.
