Moor
As Anmoor or half-bog soils are mineral soils referred to, by virtue of excess water and oxygen poverty a high content of organic matter (15 to 30% by mass of organic matter) dm powerful Aa-horizon (to the 1-4 CH5 own). The term 'anmoorig' describes a pedogenetic horizon feature of the topsoil.
Brief description
Often it is very acidic or moist to wet mineral soils, in which there is no complete decomposition of plant material and a high proportion of raw humus can persist. Moorish soil horizons can often be found in marshes and on gley soils , where z. B. the soil type Anmoorgley (gley soil with a high proportion of raw humus). Half-bog soil layers also often form in the landscape context a transient form from the soil type norm Gley to soil type Moor includes, which floors at least 30 percent by mass of organic matter and at least 30 cm thickness. Moorish soils were also created by human intervention (anthropogenic soils), e.g. B. by deep plowing of moors for amelioration ( deep plowed soil ) or in heaths created by pest management . Other soils can also be described as boggy, e.g. B. Forest soils that have a high proportion of undecomposed deciduous and coniferous litter (e.g. oak or coniferous forests).
