Biodynamic agriculture is a modern organic farming that includes concepts from a theory drafted by philosopher Rudolf Steiner. It is a form of alternative agriculture but is different from others type of organic agriculture for its spiritual, mystical and astrological orientation.
Biodynamics is very similar to other organic approaches that use manures and compost and excludes the use of artificial chemicals on soil and plants. A lot of herbal and mineral additives are used in biodynamic agriculture for compost additives and field sprays.
Some biodynamic methods use an astrological sowing and planting calendar.
Biodynamic agriculture farming practices have been found to be more resilient to environmental challenges, to foster a diverse biosphere and to be more energy efficient than non-organic agriculture.
