Compost preparations (502–507) for soil vitality
The contribution, measured
Time horizon: 1–3 seasons
How it contributes
They steer composting toward a stable humus and good nutrient cycling, the base of soil fertility.
What to measure for this pairing
Why this goal matters
Biodynamics puts soil life at the centre. The preparations and biodynamic compost aim to stimulate biological activity, humus formation and rooting — a living soil as the base of a balanced vine.
In practice this is measured as in any good soil management: organic matter, structure, biological activity and rooting. What sets biodynamics apart is the systematic use of the preparations and the logging of applications across the calendar.
Goal indicators
Market & certification: Soil vitality is the pillar of the biodynamic story and a practical requirement of Demeter certification.
How to apply the practice
- 1Obtain or make the six preparations.
- 2Insert 502–506 into cavities in the compost pile.
- 3Spray valerian (507) over the pile.
- 4Log the build and the use of the treated compost.
Frequently asked
Do I need all six preparations?
Yes — the 502–507 set is used together in biodynamic compost and is required for Demeter certification.
Can I buy the preparations ready-made?
Yes, there are suppliers and biodynamic associations; many growers choose to make their own over time.
