3.5.4 Nutrient Deficiencies

Оглавление

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 Ca2 + in plants that cause necrosis of the leaf (Abdulnour et al. 2000).
