Biodynamics - Planetary Calendar
Biodynamics works to nourish the Earth, respect living things, the terroir and strengthen soil life and plant health. It is a balanced form of farming that builds on good agronomic practices used in organic agriculture by enlivening the soil with preparations based on medicinal plants. It uses solar, lunar and planetary rhythms.
