Horn manure (500) for demeter certification
The contribution, measured
Time horizon: Ongoing
How it contributes
Using 500 is mandatory under Demeter; each application must be logged and traceable for the audit.
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
- 1Dynamise the preparation in warm water for an hour.
- 2Spray onto the soil at day’s end, in coarse droplets.
- 3Favour root days and the descending calendar phase.
- 4Log rate, plot and date for certification.
Frequently asked
When is 500 applied?
Typically in the late afternoon/evening, on root days and descending-sap phases, over moist soil — a few times a year.
Can I make 500 on my own farm?
Yes — many growers bury the horns and make the preparation, which reinforces the self-sufficiency Demeter values. Ready-made preparation can also be bought.
