Interrow cultivation and intercropping for organic transition in dryland crop production systems
CSANR Project 120
Protecting wheat during the transition to organic production and managing soil nitrogen during the organic production phase represent major impediments to increasing organic acreage. We have developed a system that incorporates weed control and the use of a pea intercrop as a source of nitrogen to address these impediments by intercropping winter pea with winter wheat, and view the system as viable transition and production tactic. We intend to apply for an USDA-OTS or USDA-OREI grant to develop the system further, and view the BioAg support as seed money for that effort. This grant addresses all four priority areas as set forth in the RFP. Our continued objectives are: 1) Determine what time of year to mechanically remove a legume intercropped with wheat to provide the greatest amount of N to the crop. 2) Assess the utility of an interrow cultivator for precision weed control and to remove an intercropped legume.
