Cation exchange capacity in effective root space

The evaluation map shows the derived values for cation exchange capacity (KAK) of a soil in the form of KAK levels. These input data are necessary for the evaluation of the soil subfunction “Filters and buffers for pollutants” and were determined according to fine soil type and coarse soil content as well as humus levels of the mineral soil using Saxon soil assessment instrument (LfULG, 2021).

本评估图谱以KAK数值水平的形式呈现了土壤阳离子交换量（cation exchange capacity, KAK）的衍生计算值。此类输入数据是评估土壤子功能"污染物过滤与缓冲功能"的必要依据，其结合细粒土壤类型、粗粒土壤含量与矿质土壤腐殖质水平，通过萨克森州土壤评估工具（Saxon soil assessment instrument, LfULG, 2021）测算得到。
