Dr. Katalin Juhos' field of expertise is the monitoring of indicators of soil quality and soil health and their analysis using machine learning methods. Her current research area is the measurement and validation of the amino-nitrogen content of soils and the impedance of plants by setting up model pot experiments. Since the functions of soils, such as their ability to supply nitrogen, can not only be measured by soil tests but are also indicated by the plants themselves, with the  application of  soil and plant physiology methods together, she seeks answers to the following questions: (1) is amino-nitrogen suitable for soil mineralization to characterize its potential, (2) can impedance-based monitoring methods demonstrate the nitrogen supply capacity of different soils and the actual N supply of plants?
