Vineyard soils are particularly poor in organic matter, which is a critical weakness when facing climate change.
Bringing compost to a vineyard, associated to an improved soil management (grass bands, no-till tecnics, shredding...) should answer to more than one climatic constraint :
- increasing the soil available water capacity : an additionnal 1% carbon retained in the soil could increase by 20% the amount of water available for the vine
- securing the amount of nutrients available for the plant
- improving the soil structure and the vine's rooting, which means offering a better resilience to climatic hazards
- directly and indirectly retaining more carbon
- recycling organic wastes from plant and/or urban activities
In order to conduct such improvements actions, there is a wide choice of compost types, different levels of application and burying strategies.
