Crimson clover: the key ingredient to nutrient-rich soil

Crimson clover is a plant that is often used as a cover crop.

In viticulture, as well as in other types of agriculture, cover crops can be planted alongside already existing crops, with the result of improving the productivity, biodiversity and general health of the agroecoystem. The cover crop’s purpose is not to be harvested itself, but instead to cover any remaining areas of soil and work its magic by: fertilising it, preventing erosion, improving its structure, attracting wildlife and reducing weeds.

At Château Fontesteau, we have chosen the vibrant crimson clover, or Trifolium incarnatum, as our main cover crop and source of green manure. A common choice in orgamic farming, each winter we plant the nitrogen-rich crop amongst our vine plots, reducing the need for any sort of artificial fertiliser.

We often choose to also plant oat and field bean plants alongside the crimson clover; this variety of cover crops works well in our vineyard and each year we choose which and how much depending on the soil’s deficiencies.

As a certified organic vineyard (ECOCERT BIO-FR-1) that also practices conservation grazing, we are constantly searching for new and innovative ways to manage our land and adapt our practices to the changing climate. Biodiversity protection is the primary objective in every choice we make.
