Compost preparations (502–507) for demeter certification
The contribution, measured
Time horizon: Ongoing
How it contributes
The compost preparations are mandatory under Demeter; their use must be documented for each pile.
What to measure for this pairing
Why this goal matters
Demeter is the leading biodynamic certification. It requires the organic base plus the use of the biodynamic preparations, managing the farm as an organism, biodiversity quotas and its own cellar rules.
In practice, gaining and keeping Demeter is mostly a matter of doing — and proving. Every preparation application, operation and input has to be logged and traceable for the annual audit.
Goal indicators
Market & certification: The Demeter seal is a strong market differentiator and the formal goal of most biodynamic projects.
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.
