Detailed explanation-4: -Calcium is an essential macronutrient in plants, with concentrations in the shoot ranging from 0.1 to over 5% of dry wt (Marschner, 1995; White and Broadley, 2003). It thereby exhibits a dual function, both as a structural component of cell walls and membranes and as intracellular second messenger.

Detailed explanation-5: -Magnesium (Mg) is one of three secondary macronutrients, along with calcium and sulfur, required for balanced crop nutrition. Often overlooked, Mg deficiencies can lead to reduced crop growth and yield.
