Under-vine mulching (herbicide-free)

Control the row with mulch instead of herbicide.

The strip under the vine is the last stronghold of herbicide in many vineyards. Organic mulch — straw, wood chip, pomace, chipped prunings — replaces it, suppressing weeds by shading and physical barrier.

At the same time, mulch cuts evaporation, moderates soil temperature and, as it breaks down, feeds soil life in the zone of highest root density. It is one of the most direct ways to eliminate glyphosate without resorting to intensive mechanical weeding.

Soil health & structure

Mulch decomposition feeds soil life in the zone of highest root density and adds organic matter in the row.

Time horizon: 1–3 seasons

Row organic matterSoil biological activity

Water resilience & drought

The cover sharply cuts soil evaporation in the row, conserving moisture in the root zone.

Carbon sequestration & climate

It valorises organic residues as cover and cuts the diesel of repeated mechanical weeding in the row.

How it works

A layer of organic matter blocks the light weeds need and cuts evaporation, while it decomposes and feeds soil life in the row.

How to implement

  1. 1Choose the material (straw, wood chip, pomace, chipped prunings).
  2. 2Apply a layer thick enough to shade the row.
  3. 3Top up as it breaks down.
  4. 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.

Implement and document this practice by plot, with an audit-ready history.

Phytosanitary register & copper (Portugal)

In Portugal, 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 (Portugal)

In Portugal, log every operation — cover sowing, grazing, composting, mowing — by plot and date, with an audit-ready history that proves the practice over the years.
