Continuous salt accumulation in soils over a period of time can cause an ionic imbalance in plant cells that inhibits the absorption of core elements like Ca²⁺, K⁺, and NO₃²⁻. Accumulation of Na⁺ and Cl⁻ ions in soil induces nutritional deficiencies in plant tissues, which results in Na⁺ induced Ca²⁺ and K⁺, Ca²⁺ induced Mg²⁺ and Cl⁻ induced NO₃²⁻ deficiencies (Grattan and Grieve 1992). Excess boron in soils results in deficiencies of Ca^{2 +} in plants that cause necrosis of the leaf (Abdulnour et al. 2000).
