Effect of water quality on the leaching of potassium from ...

When potassium (K +) fertilizers are applied to soil, K + is subject to displacement through the soil profile. More generally, the application of K + fertilizers to sandy soils with low clay content and small buffer capacity, in which K + does not interact strongly with the soil matrix, results in localized increases in K + concentration in the soil solution.
