  1. The UNH Organic Research Dairy Farm (ODRF) Ecosystem: Nitrogen Cycle Gabriel Perkins Dr. John Aber The Purpose of this study was to identify the major flows of nitrogen within the ODRF, with the idea that this information would provide insight on the necessary steps for, and potential of, creating an increasingly self-sustaining system. Located on the Burley-Demeritt Farm in Lee, New Hampshire, the 60 hectare ODRF is the first land-grant institution operated, commercial-scale, research organic dairy in the country. http://www.organicdairy.unh.edu/index.html • The major nitrogen flows at ODRF include: • Manure • Hay • Silage • Baleage • Grain • Forage • Milk • And Feed Additives As with any study, there are areas within this meta-analysis that need further attention. My data highlights a gain of 4,156.4 kg*N/yr, which implied the possibility of reducing imported Nitrogen. Further research should focus on the potential for increasing on-site manure spreading and baleage, bedding, hay, and/or silage production.
