Soil biology & mycorrhizae for carbon sequestration & climate

The impact, measured

58 /100

Time horizon: 3–6 seasons

Why it works

Glomalin and fungal biomass are stable carbon pools, contributing to soil sequestration.

What to measure for this pairing

Soil glomalinSoil organic carbon

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.

How to implement the practice

  1. 1Keep living roots year-round with a permanent cover.
  2. 2Avoid tillage that ruptures the hyphal networks.
  3. 3Moderate phosphorus and soil fungicides that inhibit the fungi.
  4. 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.
