The second Field Guide contains information compiled from additional questions and correspondence about using and applying Actively Aerated Compost Tea to build and improve your soil's biology.
This handbook was created in response to farmers who completed Rodale Institute's online Transition to Organic course and wanted a guide they could take into the field to reference.
