摘要：

The actual cation exchange capacity (CECact) in sandy mine soils from Tertiary sediments increases with the lignite contents of the substrates. Therefore, lignite is important for nutrient storage and availability in these soils. Base saturation varies over a wide range of 4 - 100% according to soil pH. For the determination of CECact, the high contents of soluble salts typical for these substrates have to be considered for reliable results.
