Since 1962, the soil inventory (RIS-MI) and the national forest inventory (RIS-RT) have had a common field organization. The soil inventory investigates soils and collects soil samples for laboratory analysis. It includes several soil variables, e.g. soil type and soil classification, stone and boulder abundance, water relations, and soil chemistry. Simultaneously to the soil inventory, RIS–MI samples the field layer vegetation.
