Theme III. Agricultural use of peat and peatlands
Labile organic carbon fraction is cycling fast in the environment. One of labile organic carbon compounds is carbon extracted with hot and cold water. Water-extractable organic carbon does not include all labile organic compounds. However, it is a good indicator of peatland organic matter quality. The studied peatland had undergone the process of organic matter transformation, known as muck-forming process. During this process, intense mineralization and humification of organic matter took place. The contents of cold and hot water-extractable organic carbon fractions were up to 1% of total organic carbon. The results of the study proved that water-extractable carbon fraction is a good indicator of changes in peatlands.
