Cover crops like bristle oat (Avena strigosa) and common vetch (Vicia sativa)\nmay contribute to soil C sequestration via root biomass and rhizodeposition, including root exudates,\nbut C storage potential at the species and varietal levels for these plants remain poorly documented,\npartly due to difficulties in measuring root exudation under field conditions. This study compared four\ncultivated varieties of bristle oat and common vetch, focusing on their root and exudate C content and\nmetabolic profiles. Distinct metabolite profiles were identified mainly at the species levels. Oat roots\nhad a reduced C content compared to vetch roots although they contained more amino acids, sugars,\norganic acids and specialized metabolites. On the contrary, C content was higher in oat exudates\nwith more fatty acids and specialized metabolites while vetch exuded more sugars, organic acids and\nnucleotides. These results suggest that the mixture of these two plants can produce complementary C\ndeposits, enhancing C storage and allowing the construction of a rich (microbial) soil ecosystem.","language":"eng","keywords":[],"project":{"code":"21ASV002","name":"Recherche de variabilité de spécifique et variétable pour le stockage de carbone dans le sol grâce aux couverts d'interculture"},"notice-url":"https://www.nature.com/articles/s41598-026-44751-7","document-url":"https://rd-agri.fr/rest/content/getFile/c20bbabb-16a0-47a4-8b4c-49f29d3d2fe8/s41598-026-44751-7.pdf","productions":[],"taxa":[],"production-systems":[],"areas":[],"pests":[]}
