The bivalent cations such as Ca²⁺ and Mg²⁺ tend to flocculate, which facilitates penetration of water into roots, whereas the monovalent cations such as Na⁺ and K⁺ disperse the clay particles, which reduces the porosity of the soil. Hence the excess amount of Na⁺ and K⁺ has a profound impact on the relationship between soil and water, resulting in soil erosion and crop failure (Chibowski 2011).
