Composting & compost extracts for water resilience & drought
The impact, measured
Time horizon: 2–5 seasons
Why it works
The added organic matter raises the soil’s water-holding capacity, especially in light, poor soils.
What to measure for this pairing
Why this goal matters
In Mediterranean climates water is the limiting factor. Regenerative viticulture manages soil to infiltrate more rainfall, cut evaporation and raise plant-available water — so the vine leans less on irrigation and rides out summer stress.
Covered, organic-matter-rich, deeply-rooted soil holds more water and loses less to run-off and evaporation. Tracking soil moisture and water use per hectare shows the return on these practices across seasons.
Goal indicators
Market & certification: Critical where water is scarce or licensed; the basis of dry-farmed wine claims.
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.
