The role of nitrogen and iron biogeochemical cycles in the production and export of dissolved organic matter in agricultural headwater catchments

Data on soil solutions collected in the riparian area at 15 cm depth in an agricultural catchment in Brittany (France) during one hydrological cycle. Zero-tension lysimeters were collected at a fortnightly frequency from October 2022 to June 2023. Measurements inlcude dissolved organic matter concentration and composition (3D flurorescence), nitrates, iron, and phosphorus. Data are published in Lambert et al., 2014, The role of nitrogen and iron biogeochemical cycles in the production and export of dissolved organic matter in agricultural headwater catchments, doi.org/10.5194/egusphere-2024-1212 (preprint).
