By an example in the landscape of the Lewitz in the south-western part of Mecklenburg-Western Pomerania it is shown, how actual properties of peat-soils are influenced by historical land-use. Beside that the site is validated according its mineralisation rate, C-stock and C-release potential. An average loss in peat thickness of 2,9 dm between 1974 and 2011 could be stated. At two specific sites digging stated a decrease of mineralic components in the upper layer in the same period. One background for this is seen in the uncertainty in finding the exact former digging sites, whereas other reasons are physical changes due to agricultural and constructional activities in former times. The actual average carbon stock of the Polder Schwarzer Graben II area is 678 t C ha-1 with an average peat thickness of 6 dm. Between 1974 and 2011 a carbon amount of 134 t C ha-1 was released. This equals an emission rate of approximately 3,6 t C ha-1 a-1. %U http://resolver.sub.uni-goettingen.de/purl?gldocs-11858/7183 %~ FID GEO-LEO e-docs
