Lower-Saxony is located in North-West Germany, East of the Netherlands and ending in the North Sea. This region is known for its wetlands and bogs, which represent today only about 5% of its total surface. These were and are mainly made of peat also called also turf, which is a deposit soil formed by the partial decomposition of vegetal matter in wet acidic conditions. Left in the sun for drying, peat was used as a fuel for cooking and heating.
