Bio-Dynamic Gardening and Farming, Volume 2

Despite the increasing number of publications on Bio-Dynamic gardening and farming, it seems appropriate to go back occasionally to the work of one of the great pioneers in this endeavor, Dr Ehrenfried Pfeiffer. The first of three volumes was published earlier this year and with this volume we present the second of three planned volumes of articles by Dr. Pfeiffer.
