LGRB-BW BK50: Potential cation exchange capacity

The determination of field capacity (FK), usable field capacity (nFK), air capacity (LC), saturated water conductivity (kf value), potential cation exchange capacity (KAKpot) and the K-factor (ABAG) is mainly based on the estimate sizes of soil type, humus content and effective storage density for mineral soils or decomposition and substance volume in moor soils. Only the predominant soils with a land share of more than 25 percent are taken into account.
