Research activities:

This participatory, on-farm research project addressed the following objectives:

  1. Identify legume cover crops (grown in monocultures and mixtures) that build SOM and
    increase nutrient cycling capacity on organic vegetable farms.
  2. Identify rotations and management practices that maximize BNF and reduce N
  3. Develop workshop activities and outreach materials to share information with smallscale,
    organic vegetable farmers of varying levels of experience.
