Summary
Potassium selectivity for cation exchange equilibria (mono-divalent) in some submerged soils (Molic gleysols) in the midland of the Red River watershed
In practice one can use the Gapon selectivity to predict the behaviour of mono-divalent exchange in this kind of soil for a balanced fertilization of potassium and magnesium I intensive rice cultivation not only for short but also for long term.
