What is Biodynamic Agriculture?
Biodynamic farming extends organic practices by viewing the farm as a self-sustaining organism. Developed by Rudolf Steiner in the 1920s, this approach emphasizes cosmic rhythms, specially prepared composts, and farm biodiversity to create vital, healthy food.
Biodynamic Preparations
BD 500 (horn manure) enhances soil life and root development. Bury cow manure packed in cow horns over winter, then dilute and apply in spring by stirring in specific patterns to energize the preparation.
BD 501 (horn silica) promotes photosynthesis and crop quality. Apply as a fine mist during morning hours on growing plants to enhance light metabolism and plant vitality.
Compost Preparations
Six herbal preparations (yarrow, chamomile, nettle, oak bark, dandelion, valerian) guide composting processes. Each preparation influences specific aspects of nutrient transformation and compost maturation.
Add preparations to compost piles in small quantities - their effect comes from biological activation rather than material quantity. Well-made biodynamic compost develops a pleasant earthy smell and fine crumbly texture.
Cosmic Rhythms and Planting Calendars
Biodynamic farmers consider lunar phases and zodiac positions when timing farm activities. Root days favor root crops, flower days suit flowering plants, leaf days benefit leafy greens, and fruit days help fruit and seed crops.
While scientific validation remains debated, many practitioners report improved germination, vigor, and yields when working with cosmic rhythms. Experiment on small scales before committing entire operations.
Demeter Certification
Demeter is the biodynamic certification program, requiring organic practices plus specific biodynamic methods. Farms must use biodynamic preparations, maintain at least 10% of land for biodiversity, and integrate livestock where feasible.
Certification provides market access to consumers seeking the highest quality organic products and commands premium prices for the additional care and practices required.
