WebOct 28, 2024 · The RSC formula is a quick test to determine if irrigation water can reduce free Ca and Mg in the soil. RSC is calculated by: RSC (meq/L) = (HCO 3 + CO 3) – (Ca + Mg), where all ion concentrations are in meq/L. A negative RSC value indicates little risk of Na accumulation due to offsetting levels of Ca and Mg.
