Changes in humus form, humus stock and soil organic matter distribution caused by forest transformation in the north-eastern lowlands of Germany [German]

摘要

The purpose of the present survey was to describe the effects of. forest transformation on humus ecology in north-eastern lowlands of Germany. A chronosequence was developed from four stands: one pure Scots pine experimental plot (K 75 R, 84 years old), two Scots pine stands with a beech understory (K 74 NE, 34 years old and K 75 M, 57 years old) and a beech stand (K 86) with an age of 91 ears. Sections were set up at each site along which more than 400 humus bricks were characterized. Additionally, the carbon content in the mineral soil horizon was analyzed down to a depth of 1.6 m.
