The Soil Fertility research group focuses on soil and waste organic matter decomposition processes and soil nutrient turnover, availability and losses in agro-ecosystems.
Our research aims at a mechanistic understanding of soil nutrient and organic matter dynamics at both the level of micro-scale biogeophysical processes and at eco-system scales, in the pursuit of increased nutrient use efficiency, improved food security and reduced environmental impacts from agriculture in the 21st century.
The Soil Fertility research group covers four main research topics (see bubble diagram), where the central topic soil fertility and nutrient availability forms the core of our research identity, but interacting with the other three more applied topics, ensuring a coherent research focus.
- Soil fertility and nutrient availability
- Recycling of nutrients from organic waste and bio-based fertilisers
- Environmental impacts of agricultural use of mineral and bio-based fertilisers
- Changes in land use and soil quality, carbon stocks and greenhouse gas emissions
- Long-term field experimental facilities
- Nutrients for higher organic crop yields (NutHY)
- Sustainable cultivation concepts in agriculture (CarbonFarm)
- Nutrient accounting with soil pool changes and losses as decision support (StyrN)
- The impact of increasing spruce plantation area on the carbon balance of forests in Western Norway (BalanC)
- The Future Cropping Alliance
- Microbial biofertilizers for improved crop availability of phosphorus from soil and waste (MiCroP)
- Greenlandic glacial rock flour for soil improvement on depleted tropical soils
