Under-vine mulching (herbicide-free) for soil health & structure
The impact, measured
Time horizon: 1–3 seasons
Why it works
Mulch decomposition feeds soil life in the zone of highest root density and adds organic matter in the row.
What to measure for this pairing
Why this goal matters
Soil health is the foundation of regenerative viticulture. A soil with good structure, biological activity and organic matter infiltrates and holds more water, releases nutrients gradually and supports a vine that leans less on external inputs.
It is measured by organic matter, aggregate stability, infiltration and soil life (earthworms, microbial respiration). Every one of these responds to how you manage cover, tillage and added organic matter — and all are recordable season over season.
Goal indicators
Market & certification: Increasingly required by sustainability schemes and buyers auditing soil practices.
How to implement the practice
- 1Choose the material (straw, wood chip, pomace, chipped prunings).
- 2Apply a layer thick enough to shade the row.
- 3Top up as it breaks down.
- 4Record the area kept herbicide-free.
Frequently asked
Doesn’t mulch attract rodents or disease?
A well-managed, aerated mulch is rarely a problem. Keeping the layer off the trunk and choosing suitable materials minimises any risk.
How much material per hectare?
It depends on row width and layer thickness, but on-site prunings, pomace and chip cover much of the need.

How GrapeFlow helps
The proof certification and buyers ask for — logged by plot and date.
Phytosanitary register & copper balance
Every treatment is logged with product, rate and active substance, and copper is summed on the 7-year rolling mean — direct proof of input reduction.
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.
