Biochar & carbon amendments for carbon sequestration & climate

The impact, measured

88 /100

Time horizon: Immediate and permanent

Why it works

It is the most durable form of vineyard sequestration — recalcitrant carbon that stays in the soil for centuries.

What to measure for this pairing

Stable carbon locked in (t C/ha)Pruning biomass valorised

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.

Market & certification: Relevant for footprint reporting, low-carbon labels and agricultural carbon credits.

How to implement the practice

  1. 1Gather woody biomass (prunings) as feedstock.
  2. 2Produce biochar by controlled pyrolysis.
  3. 3Charge the biochar with compost or nutrients before applying.
  4. 4Incorporate under-vine or blend into compost.

Frequently asked

Can I make biochar from prunings?

Yes — prunings are an ideal feedstock, and making biochar instead of open-burning them avoids emissions and creates a valuable amendment.

Why must biochar be “charged”?

Fresh biochar can temporarily immobilise nitrogen. Pre-charging it with compost or nutrients avoids that and speeds up the benefit.
