To restore the ecosystems of lakes

When lake ecosystems work well, water quality is good. This allows us humans to use the resources that water constitutes. We can fetch drinking water from clean water bodies, use it to go for a swim,

The fate of environmentally hazardous PFAS substances in the soil has been investigated

Highly fluorinated substances, or PFAS substances, are a group of chemicals that in recent years have come to be regarded as environmental contaminants of global concern. In his doctoral thesis, Hugo

Effects of structure liming on clay soil

Structure liming is a method to stabilise clay aggregates and thereby reduce the risk of phosphorus losses. In his new doctoral thesis, Jens Blomquist has evaluated the efficiency of this practice.

How does naturally occurring and added nitrogen affect ectomycorrhizal communities?

Ectomycorrhiza is a symbiosis between forest trees and fungi. Ectomycorrhizal fungi are extremely important for the trees’ nutrient uptake. Nitrogen affects these fungi in different ways depending on
