I am a professor in soil chemistry and plant nutrition. Most of my research has been related to phosphorus and potassium in cultivated soil, the availability tested in laboratory and field experiments and to improve the recommendation for farmers based on soil chemical analysis. Focus is to optimize the use of fertilizers to obtain fodder and products of good quality and at the same time to minimize the environmental problems. Soil phosphorus problems related to eutrophication of fresh water is another important topic of my research.
I am manager of the laboratory for soil and water chemistry and soil physics at the faculty.
