Biodynamic compost for soil vitality
The contribution, measured
Time horizon: 1–3 seasons
How it contributes
It returns stable humus, nutrients and biology to the soil — the farm organism’s main fertility source.
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
- 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.
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.

How GrapeFlow helps
The proof Demeter certification demands — logged by plot and date.
Electronic field notebook
All operations — compost, cover, animals, dynamisation — logged by plot, ready for certification.
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.
Biodiversity & ecological infrastructure
Hedges, strips and cover logged as ecological infrastructure, to meet and document biodiversity quotas.
