peat(Unconsolidated soil material consisting largely of undecomposed or slightly decomposed organic matter accumulated under conditions of excessive moisture)
peat extraction(Peat is obtained from peat bogs by cutting it from the earth; it is then formed into briquettes, which can be used as fuel. Peat may be found in layers several metres thick. In some countries peat-fired generating stations for electricity are in use. Peat is also used as a soil conditioner)
