What plants add carbon to the soil?

Plants that add carbon to the soil primarily include deep-rooted perennials like grasses, legumes, and trees. These plants capture atmospheric carbon dioxide through photosynthesis and store it in their biomass and root systems. As they grow, they also contribute organic matter to the soil through leaf litter, root exudates, and decomposing plant material, enhancing soil carbon content. Cover crops and agroforestry practices further promote soil carbon sequestration by improving soil structure and biodiversity.
