Compost preparations (502–507) for biodiversity & farm organism
The contribution, measured
Time horizon: 1–3 seasons
How it contributes
The six plants tie the farm to its medicinal flora and on-farm production, reinforcing the farm organism.
What to measure for this pairing
Why this goal matters
The “farm organism” concept is at the heart of biodynamics: the farm as a living, diverse and as-self-sufficient-as-possible whole, with animals, hedges, cover and its own sources of fertility.
It translates into functional biodiversity and ecological infrastructure — measurable in habitat area, cover diversity and beneficial presence — and into integrating animals and producing your own compost and preparations.
Goal indicators
Market & certification: Biodiversity and the farm organism are explicit requirements 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.

The proof Demeter certification demands — logged by plot and date.
Preparations & application log
Every application of 500, 501 and the other preparations logged by plot, date and rate — the history the Demeter audit asks for.
Electronic field notebook
All operations — compost, cover, animals, dynamisation — logged by plot, ready for certification.
Biodiversity & ecological infrastructure
Hedges, strips and cover logged as ecological infrastructure, to meet and document biodiversity quotas.
