What is biodynamics?
Biodynamics is a farming approach that treats a farm as a living system. It was developed by Rudolf Steiner in the 1920s and combines soil health, crops, livestock, and the farm's environment.
Key ideas
- Healthy soil supports healthy plants, animals, and people.
- Farm biodiversity and a varied ecosystem on the farm.
- Using natural materials and careful timing rather than synthetic chemicals.
- Viewing the farm as a whole, not just a collection of fields.
Typical practices
- Composting and making special biodynamic preparations from plants and minerals, used in small amounts to enhance soil and plant life. For example, some farmers use a manure-based preparation stored in a cow horn, and a silica-based preparation stored in a horn.
- Applying preparations to soil and plants only at certain times based on lunar and planetary cycles.
- Planning planting and harvesting around cycles and careful observation of the land (phenology).
- Encouraging a diverse farm with cover crops, natural pest management, and habitat for beneficial organisms.
How the special preparations work, in simple terms
In biodynamics, these preparations come from natural materials. They are used in very small amounts and in specific ways to support soil life, plant resilience, and balance on the farm. They are one part of a broader focus on soil health and biodiversity.
Real-life example: a tiny biodynamic garden
- Observe: Watch how the garden changes with the seasons and weather.
- Build soil: Add compost and organic matter to improve soil structure.
- Plan timing: Use a simple lunar-friendly calendar to decide when to plant or harvest.
- Care for life: Encourage a mix of plants and helpful insects to balance the garden.
How biodynamics compares to organic farming
Both avoid synthetic chemicals and emphasize soil health, crop rotation, and biodiversity. Biodynamics adds a holistic view of the farm as a living system, plus timing based on cycles and the use of natural preparations.
