Description of research and teaching

After retirement (since 1/2017), I have written papers, supervised students, served as a reviewer for journals and participated in some projects as a researcher.

My research activities concentrate 1) on acid sulfate soils, 2) phosphorus fertilization and 3) soil classification.

As for acid sulfate soils, the studies in which I am involved in, deal with the effect of water management on the release of acidity and behavior of metals in these soils. The research sites include 1) a coastal acid sulfate soil with a peaty topsoil at Ruukki, which is an AnaEE site Ruukki (https://platforms.anaee.eu/research-platform-index/10052-5/), 2) a former peat mining area in eastern Finland, where oxidation of black schists is the source of acidity and 3) a poldered field area at Söderfjärden on the western coast of Finland.

Other research topics include soil classification according to the World Reference Base (WRB) and Soil Taxonomy. I was involved in compiling and updating of the soil map of Finland.  The projects on soil phosphorus include/ have recently included long-term phosphorus fertilization experiments and studies of sediments of a constructed wetland with the aim of finding out what to do with the dredged sediment material. I have also had some activity on the characteristics and sustainable use of Ethiopian soils.  

My teaching included the following courses: 1) Principles of soil fertility and plant nutrition (BSc level) and 2) Pedogenesis and soil classification (MSc level). I also participated in teaching soil issues in the principles of crop production course and parts of soil chemistry in the Advanced Soil Science course.
