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 experiment 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 eutrphication 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.

Forskning & prosjekt
Prosjekter
The overall objective of CenBio is to enable sustainable and cost-efficient bioenergy.
This project will improve the understanding of how biosolids can be a future phosphorus source in food production without compromising on food safety and environmental risks.
The overall goal is to create a sound knowledge basis for increased production, productivity and sustainability in domestic food production.
