During the Late Glacial, fen peat
(mainly brown moss peat and sedge-brown moss peat) was the most common in the deposit, which means that brown moss communities dominated on the studied site.
The following organic materials were used for mulching: chopped wheat straw, regularly cut grass from grass-plots, sawdust of different tree species, and medium decomposed fen peat
At Joelahtme the buried fen peat
was earlier dated to 8700-8400 yr BP (Kessel & Punning 1974).
Stratigraphy: Found at the interface between fen peat
and Sphagnum bog peat, always associated with Calliergon trifarium but in lesser quantity.
The richness of subfossil remains in the Sphagnum-peat decreased substantially as compared to the fen peat
It is also possible to distinguish locally different peat layers from the radar images: Sphagnum-dominated relatively poorly decomposed bog peat is marked by numerous horizontally oriented and undulating reflectors, while the underlying strongly decomposed fen peat
is lacking inner reflectors (Fig.
The H/C ratios in HAs from Eipurs Bog in fen peat
were the lowest at a depth of 3.
Lake sediments were superceded by fen peat
, which occupied from 40-55% of the total volume of the basins of leatherleaf bogs.
The thickness of the fen peat
in the central part of the bog is about 1-1.
2]) and in the closest forested surroundings, whereas fen peat

Lower C/N ratios for the basal fen peat
([greater than] 350 cm) are explained by the lower C/N ratios of its original components (Kuhry et al.
Germany, Austria, Finland), well-humified raised bog and fen peat
is used, from raised bogs mainly Sphagnum (humification H6-H8) and from fens Carex peat (humification H8-H10) (Naucke 1981).
