Composting & compost extracts for biodiversity & ecosystem
The impact, measured
Time horizon: 2–4 seasons
Why it works
Inoculates and feeds the microbial community and soil fauna, raising below-ground biological diversity.
What to measure for this pairing
Why this goal matters
Functional biodiversity turns the vineyard into a self-regulating ecosystem. Beneficials keep pests in check, pollinators and cover-crop flora support the food web, and diversity above and below ground buffers climate and disease shocks.
It is measured through ecological infrastructure (hedges, flower strips, walls), beneficial abundance and diverse ground cover. It is also an explicit requirement of schemes such as sustainability certification and integrated production.

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.

How GrapeFlow helps
The proof certification and buyers ask for — logged by plot and date.
Electronic field notebook
Log every operation — cover sowing, grazing, composting, mowing — by plot and date, with an audit-ready history that proves the practice over the years.
Sustainability & carbon-footprint module
Water, energy, fuels and ecological infrastructure in one place, with the carbon footprint computed per season and per bottle.
Plot registry & map
Every practice tied to the right plot on the map, with area, variety and history — so you know where you did what and can compare blocks.
