|Abstract:||The presence and transformations of nitrogen (N) in the environment depend on a variety of environmental factors but are also strongly influenced by anthropogenic activities such as modern agriculture. Understanding N transformations within the context of agricultural systems is crucial for efficient use thereof. The aim of this study was to investigate the changes in concentration of N forms (ammonium, nitrite, nitrate and organic N) within an aquaponic system, a modern agricultural system, in order to obtain insights into environmental pressures influencing N transformation processes. By measuring the concentrations of the individual N compounds, complemented by the determination of abiotic parameters and other relevant nutrients within the system water at 13 sampling points, significant differences between compartments that build up an aquaponic system could be demonstrated. These differences were attributed to individual microenvironments specific to the aerobic loop, anaerobic loop and radial flow settler as a connection between the two, shaping the microbial processes within the aquaponic system.|
