Web2 Feb 2024 · Sumthe total of cations and anions: TDS [mg/L] = Cations [mg/L] + Anions [mg/L] How do I calculate TDS from conductivity? To calculate TDS (total dissolved solids) from electrical conductivity (EC), use the formula: TDS [mg/L] = kₑ × EC [μS/cm] where: EC– Electrical conductivity of the water at 25 °C; and kₑ– Multiplier or conversion factor. Web17 Dec 2024 · Base saturation is the sum of base cations (Ca 2+, Mg 2+, 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 Figure 2. For this reason, the amount of cations on the exchange sites will be limited as the soil pH decreases or becomes more acidic due to the …
