Throughout his three decades of research, Dr. István Csízi has consistently conducted and led research on grassland management. His specific field of interest is the changes in plant stand structure and phytomass yield of semi-natural grass communities in saline soils of Solonyec under the influence of various factors. In parallel, he has been involved in experiments and tender projects related to sheep breeding, the utilization sector most closely related to grassland cultivation. He has tried to stay as close as possible to market practice, as manager of the University's sheep farm in Karcag, in order to maintain an up-to-date sense of reality in his applied research.
