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.

    Heavy machinery jeopardises the promises of conservation agriculture

    Conservation agriculture is a system where the aim is to disturb the soil as little as possible. It involves sowing directly into the residues from the previous crop without tillage. Now researchers are warning that the benefits that are sought may be jeopardized by the use of heavy machinery.

    Increased amounts of mineral nutrients in Swedish forest soils, despite intensive forestry

    Are Swedish forest soils depleted in nutrients by forestry and increased tree growth? No, a new study reports that levels of important mineral nutrients have increased in the organic layer over the past 40 years. Reduced acid rain and uplift of nutrients from the mineral soil are suggested reasons.
