Composting & compost extracts for input reduction & vine resilience
The impact, measured
Time horizon: 2–4 seasons
Why it works
Supplies slow-release nutrients from by-products, cutting reliance on bought mineral fertiliser.
What to measure for this pairing
Why this goal matters
Cutting inputs lowers cost and environmental pressure without sacrificing the vine. Living soil and a balanced vine need less nitrogen, less herbicide and less fungicide — and tolerate pests and disease better.
The route is replacing routine interventions with informed decisions: soil-driven nutrition, pest monitoring and integrated protection. Recording what you apply — and what you no longer apply — is what proves the reduction and stays inside limits such as organic copper caps.
Goal indicators
Market & certification: Required by organic, integrated production and the EU copper cap (28 kg/ha over 7 years).
How to implement the practice
- 1Gather and balance carbon and nitrogen sources (stems, pomace, manure).
- 2Build windrows, monitor temperature and moisture, and turn.
- 3Let it mature until stable (dark, no ammonia smell).
- 4Apply under-vine or brew extracts for foliar/irrigation use.
Frequently asked
Can I compost pomace and stems from harvest?
Yes — they are excellent carbon and nutrient sources. Balance with a nitrogen source (manure) and let it mature to avoid acidity and seed issues.
Compost or compost tea?
Compost delivers organic matter and structure; tea delivers mostly biology. Many programmes use both — compost under-vine, extracts to boost soil life.
How often should I apply?
Modest, regular applications (2–5 t/ha) over years beat a single massive dose, both in soil response and cost.
