Mechanical weeding for nutrition & fertility
The effectiveness, measured
Time horizon: 1–2 seasons
Why it works
By incorporating weeds and cover shallowly, weeding returns organic matter and releases nutrients in the row.
What to measure for this pairing
Why this problem matters
Without synthetic mineral fertilisers, organic nutrition is indirect: you feed the soil, and the soil feeds the vine. Nitrogen comes from legumes and organic matter, and mineralisation runs at the pace of soil biology.
That requires planning — green manures, authorised organic amendments and regular analyses — to balance vigour and yield without the excess that raises disease susceptibility. Organic nutrition is soil management, not a fertiliser bag.

Certification & rules: Only authorised inputs; traceability of applications is required at certification.
How to apply the means
- 1Choose the intercep tool suited to the soil and vineyard.
- 2Intervene at the right soil-moisture window.
- 3Combine with mulch and cover to cut passes.
- 4Log passes and herbicide-free area treated.
Frequently asked
Doesn’t mechanical weeding damage the vines?
Modern intercep tools with a feeler retract from the trunk automatically. The right setup and speed minimise any risk.
How do I cut the number of passes?
By combining with row mulch and a competitive inter-row cover, which suppress weeds and reduce the need to weed.
