WaterInput reduction & vine resilience

Under-vine mulching (herbicide-free) for input reduction & vine resilience

The impact, measured

80 /100

Time horizon: Immediate

Why it works

It replaces row herbicide with a physical barrier, eliminating glyphosate without intensive mechanical weeding.

What to measure for this pairing

Herbicide appliedHerbicide-free area

Why this goal matters

Cutting inputs lowers cost and environmental pressure without sacrificing the vine. Living soil and a balanced vine need less nitrogen, less herbicide and less fungicide — and tolerate pests and disease better.

The route is replacing routine interventions with informed decisions: soil-driven nutrition, pest monitoring and integrated protection. Recording what you apply — and what you no longer apply — is what proves the reduction and stays inside limits such as organic copper caps.

Market & certification: Required by organic, integrated production and the EU copper cap (28 kg/ha over 7 years).

How to implement the practice

  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.

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.
