A multifunctional partner for the vineyard: the forage pea

The forage pea, scientifically known as Pisum sativum, is an annual legume whose varieties—much like vetch—can be sown for various purposes within sustainable viticulture. It is frequently used as a cover crop, providing numerous agronomic benefits. Its diverse varieties, distinguished notably by seed colour and size, adapt to varying climatic conditions for either winter or spring sowing, although winter sowing is often more productive due to an extended growing cycle.

The agronomic virtues of forage peas in the vineyard

Integrating forage peas as cover crops in the vineyard is a beneficial practice that contributes significantly to biodiversity and the health of living soils. As legumes, peas possess the ability to fix atmospheric nitrogen into the soil, naturally enriching the ground and reducing the reliance on synthetic fertilisers. This property is crucial for building soil organic matter and supporting vine growth.

Beyond nitrogen fixation, forage peas help structure the soil thanks to their root system, preventing erosion and improving water infiltration. Once mown or tilled into the ground, they act as a green manure, delivering valuable nutrients back to the soil. This practice aligns perfectly with an agroecological approach to viticulture, fostering more resilient ecosystems. Sowing peas in multi-species mixes alongside crops such as rye or vetches—often used as an overwintering mix—also provides an excellent source of forage that can be utilised for livestock or as organic manure.
