Cover cropping for carbon sequestration & climate
The impact, measured
Time horizon: 3–5 seasons
Why it works
Cover-crop photosynthesis injects carbon into the soil via roots and residue; accumulation is real but slow and reversible under tillage.
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.

How to implement the practice
- 1Choose the mix for the objective (nitrogen, biomass, decompaction).
- 2Sow in autumn, using the moisture and mild temperatures.
- 3Manage in spring by mowing or rolling before water competition sets in.
- 4Leave the residue on the surface as mulch.
Frequently asked
Do cover crops compete with the vine for water?
They can if left unmanaged. The key is to terminate or mow the cover before the dry period, leaving residue as mulch that cuts evaporation.
Which mix should I sow?
It depends on the objective: legumes for nitrogen, grasses for biomass and trafficability, brassicas to decompact. Diverse mixes give the fullest service.
Sow every inter-row?
Under dry-farming or dry years, sowing alternate inter-rows balances the benefits against water competition.

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.
