Traditionally, its substrata have been considered sediments. However, given enough time, they would promote the formation of a soil. There are two distinct biogeochemical compartments in seagrass soils, the rhizosphere and the subsoil. The main processes found in this thesis were somewhat related to organic matter accumulation and mineralization. Changes in plant physiology, affect the rhizosphere biogeochemistry, but not the subsoil.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Seagrassesmicrobial comunitiessubaquatic soilsbiogeochemistryMaterias::Investigación::25 Ciencias de la tierra y del espacio::2503 Geoquímica::250307 Geoquímica orgánicaMaterias::Investigación::25 Ciencias de la tierra y del espacio::2511 Ciencias del suelo (Edafología)::251102 Biología de suelosMaterias::Investigación::25 Ciencias de la tierra y del espacio::2511 Ciencias del suelo (Edafología)::251109 Microbiología de suelosdoctoral thesisopen access
