Riverine coupling of biogeochemical cycles between land, oceans, and atmosphere. Nutrients had no significant effect on SOM mineralization and glucose addition increased by 12% the mean SOM mineralization, evidencing the occurrence of a priming effect.Īufdenkampe, A. After 45 days of incubation, the mean SOM mineralization was 63% greater in the aquatic context, the most important CO 2 fluxes arising during the first days of incubation. Effects of LOM on soil mineralization were estimated using the difference in δ 13C between the SOM and the glucose. For both nutrient loads, 13C-glucose was added to half of the microcosms to simulate exudation of labile organic matter (LOM) by phytoplankton. We measured in a microcosm experiment simulating oligo-mesotrophic and eutrophic aquatic conditions how quickly soil organic matter (SOM) sampled in diverse ecosystems was mineralized as compared to mineralization within soil horizons. In particular, soil carbon mineralization could be enhanced by its interaction with autochthonous carbon, a process called priming effect, but experimental evidences of this process are scarce. In the context of global change, eroded soil carbon fate and its impact on aquatic ecosystems CO 2 emissions are subject to intense debates.
