Soil biology & mycorrhizae for water resilience & drought
The impact, measured
Time horizon: 2–4 seasons
Why it works
The hyphal network extends the soil volume mined for water, improving the vine’s resistance to water stress.
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
- 1Keep living roots year-round with a permanent cover.
- 2Avoid tillage that ruptures the hyphal networks.
- 3Moderate phosphorus and soil fungicides that inhibit the fungi.
- 4Consider inoculation in new plantings or degraded soils.
Frequently asked
Is it worth buying mycorrhizal inoculants?
In degraded soils or new plantings it can help, but in healthy soils the fungi are already present — the return comes mostly from letting them thrive.
What harms mycorrhizae most?
Frequent tillage, excess phosphorus and some soil fungicides. Reduced tillage and balanced nutrition are the best allies.

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.
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.
