Filters and buffers for pollutants

Description

The criterion ‘filter and buffer for pollutants’ is used for the assessment of the soil component function ‘compensation medium for material effects’. ‘filter and buffer for pollutants’ is understood to mean the ability of the soil to separate dissolved or suspended substances from their means of transport. The ability can be derived from mechanical or physico-chemical filter properties. Soils absorb substances with deposition from the air or directly by anthropogenic application, shift and store them primarily in the soil pores. Depending on the soil property, the storage or filter potential varies. The assessment of the ‘filter and buffer for pollutants’ criterion shall be carried out by assessing the potential cation exchange capacity and the air capacity of the soil down to the depth of the effective root space. The characteristics for this are: Soil type of the fine soil, coarse soil fractions, rooting depth, air capacity, soil density and humus content of the soil. For the derivation, the horizon and layer data of the guide profiles of the FIS soil are used. Soils with a high slope receive valuation discounts. The assessment does not directly assess the terrain position and climatic site conditions, although these are relevant for water storage capacity.
