The impact of agricultural land use on the composition of DOM and its effects on the aquatic carbon cycle are still largely unknown. The current study focuses on the DOM composition of different water sources (amongst others, surface runoff, soil pore water, drainage water) in response to different agricultural land use and practices (e.g. fertilization, tillage, etc.) and its effects on benthic microbial processes in stream ecosystems. In addition, sensors for in-situ high-resolution monitoring of DOM quality in water will be developed in the course of the project. ** This work is partially co-funded by the NÖ Forschungs- und Bildungsges.m.b.H. (NFB) within the Life Science Call.
