Composting & compost extracts for carbon sequestration & climate
The impact, measured
Time horizon: 3–6 seasons
Why it works
Stabilises carbon into long-lived humic forms and recycles by-products that would otherwise emit methane in landfill.
What to measure for this pairing
Why this goal matters
A vineyard can be a carbon sink, not only a source of emissions. Practices that raise soil organic matter and perennial biomass pull CO₂ out of the atmosphere and store it in the ground, while cutting diesel, synthetic fertiliser and spraying.
Soil carbon is slow to build and easy to lose to aggressive tillage. Documenting practices and measuring organic matter over years is what underpins credible carbon claims and access to low-carbon markets.
Goal indicators
Market & certification: Relevant for footprint reporting, low-carbon labels and agricultural carbon credits.
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.
