웹Further knowledge of base saturation is critical to the B CSR method. Base saturation is the sum of base cations (Ca 2+, Mg2+, K+, and Na+) held onto the soil exchange sites divided by the total CEC and expressed as a percentage. Base saturation can be described by Equation 1 and Fig. 2. For this reason, the amount of cations on the exchange sites will be limited as … 웹Base saturation is calculated as the percentage of CEC occupied by base cations. Figure 2 shows two soils with the same CEC, but the soil on the right has more base cations (in …
