Biodynamic compost
The heart of the biodynamic farm’s own fertility.
Biodynamic compost is the central fertility source of the farm organism. Made from farm manure and residues and treated with the 502–507 preparations, it returns stable humus, nutrients and biology to the soil.
It is the practical expression of self-sufficiency: closing the nutrient loop within the farm instead of relying on external fertilisers. The quality and origin of the compost, and the use of the preparations, are central points of Demeter certification.
Effort
Medium — compost management through the year.
Cost
Low with on-farm resources.
Time to result
1–3 seasons depending on rate and soil.

Contribution by goal — click through for detail and metrics.
It returns stable humus, nutrients and biology to the soil — the farm organism’s main fertility source.
Compost treated with the preparations and of on-farm origin is central to the Demeter assessment.
Closing the nutrient loop on the farm reinforces self-sufficiency and the farm-organism logic.
It feeds the vine in a balanced, slow-release way, supporting its balance.
How it works
Farm manure and residues compost with the preparations inserted, producing a stable humus that returns fertility and biology to the soil.
How to apply
- 1Build the compost from farm manure and residues.
- 2Insert the 502–507 preparations.
- 3Let it mature and apply it to the vineyard.
- 4Log origin, treatment and application.
What to measure
Frequently asked
Must the compost be from the farm itself?
Demeter strongly values on-farm fertility and limits external inputs; making compost on the farm is the biodynamic ideal and eases certification.
How is it different from ordinary compost?
Treatment with the 502–507 preparations and on-farm origin distinguish biodynamic compost from ordinary organic compost.
