Project Number: 8042-21660-004-04
Start Date: Aug 01, 2009
End Date: Apr 30, 2014
Research to address Objectives 1 and 2 will be conducted on six organic farms chosen to represent the range of environmental conditions and management systems in organic grain cropping systems of the mid-Atlantic region. Replicated plots will be established on each farm using a 3x4 factorial design in which one factor is annual winter legume type or perennial legume management and the second factor is manure application timing and method. Specific options will vary by farm and will be selected by farmers to match their specific production systems. Impact of the treatments on summer crop production and soil nutrient contents will be measured to assess which combination of management options maximizes nitrogen use efficiency from legumes plus manures while minimizing soil phosphorus loading. Enterprise budget analyses will be conducted for all treatment combinations to determine which management methods optimize economic performance. Research results will be shared using on-farm field days. Annual organic grain and forage crop workshops will be held to discuss organic grain production. Data from proposed on-farm studies and existing on-station organic research conducted in SASL will be incorporated into the eOrganic website.
