Nitrate leaching will be included in the model HD-MINTEQ to improve the simulation of acidification and eutrophication effects of forest bioenergy harvest.

The aim of the SURVED project is to increase knowledge about the impact of whole tree harvesting on the soil and water's acidification and nutritional status, with a focus on the growth phase and nitrogen dynamics in the new stand. This is done by developing HD-MINTEQ with methodology for estimating effect of nitrification and nitrate leaching. If the nitrogen turnover is not included the effect of acidification on forest fuel extraction may be overestimated.

The project is based on results from the three earlier projects ”Acidification of surface waters due to forest biofuel extraction - development of a classification tool”.


Project leader is Stefan Löfgren at the Department of Aquatic Sciences and Assessment, SLU.

Other participants are Jon Petter Gustafsson, Johan Stendahl and Therese Zetterberg at the Department of Soil and Environment, SLU, and Bengt Olsson, at the Departyment of Ecology, SLU.


The project is funded by The Swedish Energy Agency and runs during 2019-2022.
