The belowground organs of the Mediterranean seagrass Posidonia oceanica as a biogeochemical sink

Carbon, nitrogen and phosphorus accumulation in the belowground parts of the seagrass Posidonia oceanica (L.) Delile are presented. Including all the dead parts of the plant (roots, leaf bases, rhizomes and the organic matter in the sediment), values as high as 71 kg C m −2, 0.8 kg N m −2 and 0.03 k...

Description
Summary:Carbon, nitrogen and phosphorus accumulation in the belowground parts of the seagrass Posidonia oceanica (L.) Delile are presented. Including all the dead parts of the plant (roots, leaf bases, rhizomes and the organic matter in the sediment), values as high as 71 kg C m −2, 0.8 kg N m −2 and 0.03 kg P m −2 were found. Accumulation rates are estimated between 19–191 g C m −2 year −1, 0.2–2.3 g N m −2 year −1 and 0.009–0.09 g P m −2 year −1.
