Brief overview of the Soil Inventory

The Soil Inventory is part of the Swedish Environmental Protection Agency’s national environmental monitoring program. The inventory began in 1983 in collaboration with the Swedish National Forest Inventory and has since monitored the environmental status of Sweden’s forest soils and other natural lands. Each year, inventory and sampling are conducted at about 2,000 permanent sample plots. The samples are used for analyzing the soil’s chemical properties and determining the fungal community composition using DNA methods. The inventory produces data used in Sweden’s climate reporting to the UN and the EU, in national environmental goal follow-ups, in research, and as information for the public.

The inventory is conducted by the Department of Soil and Environment at SLU and falls under the Forest Program within SLU’s ongoing environmental analysis.

    The soil biota is the Earth's "biological engine," driving key ecosystem services. Besides carbon and nutrients, it also needs energy. “By including energy properties of organic inputs, we can better understand soil carbon dynamics in diversified cropping systems,” says Louis J.P. Dufour.
