Rigosol
A Rigosol is an artificial soil , by profound rearrangement of soil material (the trench is formed). This is done to improve the properties of the topsoil for agricultural use. The soil type Rigosol belongs to soil class Y , which includes terrestrial anthropogenic soils.
Among the Rigosolen often include many centuries old floors steep vineyards, where the every few decades rinsed material is brought back from the foot of the slope to the top. The topsoil is then mostly mixed with foreign material (weathered debris, loess, slag, etc.)
Podsols and parabroun earths have become rigid in order to neutralize the damming effect of the local stone or the clay enrichment horizon. Also wetlands - and marsh soils were in Rigosole converted. In the case of mixed sand culture, the remainder of the peated bog or the moor was mixed with the underlying sand for peat cultivation in order to obtain agriculturally usable soil.
A typical characteristic of a rigosol is the presence of an R horizon in the soil profile . If the soil is completely mixed, it is largely homogeneous; if the soil is plowed deep, it creates an inclined stratification. In particular, former Ap horizons can be clearly seen in the soil profile.
In the international soil classification World Reference Base for Soil Resources (WRB), mixing is expressed by the Relocatic Qualifier. Rigosols mostly belong to the reference soil group of the regosols , more rarely to the phaeozemes or umbrisols and occasionally to the arenosols .
