The BUP orgANiC project host its first writing workshop at Sandbjerg Estate from 1-3rd February 2026 with invited key scientists from IGB, Berlin (Tobias Goldhammer) and UFZ, Magdeburg (Daniel Graeber) and 14 project participants.
The event will also include the project's annual meeting, held as part of the workshop.
Anika Grosse joined orgANiC as a postdoc in November 2025 in the Department of Ecoscience at Aarhus University. After earning her Master's degree in hydrobiology in Dresden, Anika worked on her dissertation at the Helmholtz Centre for Environmental Research (UFZ) in Magdeburg and at the Technical University of Dresden.
During her Ph.D. studies, she worked on nitrate uptake and retention predictors in stream biofilms, focusing particularly on macronutrient stoichiometry. In her postdoctoral position, she will analyze DOM in different catchments and compartments. Additionally, a microcosm experiment will be conducted to measure the bioavailability of DOM depending on the season, catchment and compartments that feed the streams with water.
Meeting with the danish Agency for Green Transition and Aquatic Enviroment regarding renewal of excisting contract securing continued sampling for the orgANIC project within the National Monitoring Program for Aquatic Enviroment and Nature (NOVANA) for the sampling year sep. 2025 to aug. 2026
The project held a status meeting at AU Campus on the 15th of May 2025.

OrgANiC have planned and announced for an upcoming 3 ECTS PhD course on Dissolved Organic Matter (DOM) composition analysis and interpretation with high-throughput spectroscopic methods (2025)‘ to be held by the Institute of Ecoscience, Aarhus University under the Graduate School of Technical Sciences from 12th to 15th May 2024.
The project holds its annual meeting with all partners at AU Campus on the 5th February 2025.
Shristi Khanal has joined orgANIC as a PhD at the Dept. of Agroecology – Climate and Water at Aarhus University. Shristi is a graduate in Soil Science and Global Changes (IMSOGLO) from Ghent University and has a keen interest in soil biogeochemical cycling, nitrogen use efficiency and effective research-extension approaches.
Her PhD will be focused on DON leaching with the following project description:
DON leaching study- Project orgANiC
The release of different forms of Nitrogen into the environment is closely associated with agricultural practices and fossil fuel combustion, which are fundamentally linked to food production and energy conversion. Nitrogen in soil undergoes various transformation processes, some of which result in its loss from soil–plant systems, contributing to environmental pollution in water bodies and the atmosphere. This study delves into one of the key nitrogen loss pathways, specifically focusing on DON (Dissolved Organic Nitrogen) leaching with following objectives.
Several existing and ongoing long-term experiments of Aarhus University at three locations in Denmark (Askov, Foulum and Flakkebjerg) will be utilized to test effects of different factors on DON leaching:
Likewise, measurements of molecular composition of DOM and DON at different depths utilizing the long-term experiments, PLAP and LOOP fields will be done to study transformation processes occurring in the upper 1 m and up to 5 m depth in soil. Furthermore, the conventional subtraction method to calculate DON concentration will be compared to the direct measurement of DON using the Size Exclusion Chromatography.
