Compost preparations (502–507) for plant vitality & resilience
The contribution, measured
Time horizon: 1–2 seasons
How it contributes
A well-guided compost feeds the vine in a balanced way, supporting its vitality.
What to measure for this pairing
Why this goal matters
Biodynamics seeks balanced, resilient vines through the silica preparations, medicinal plants (horsetail, nettle) and calendar work. The aim is a vine that ripens well and better withstands stress and disease.
Resilience comes mostly from the system as a whole — living soil, vigour balance, biodiversity — complemented by the preparations. Documenting the programme lets you assess the effect over seasons.
Goal indicators
Market & certification: Plant resilience underpins the reduction in interventions that biodynamics values.
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.
