Exchangeable k
WebThe majority of plant-available Ca is exchangeable, is much greater than that found in soil solution, and is a divalent cation (Ca2+). An average Ca concentration in soil solution is approximately 0.01 mol l−1. The approximate range of exchangeable Ca is 20% to 65% of the cation exchange capacity (CEC) for most soils.
