Detailed explanation-1: -The secondary macronutrients are Calcium (Ca) Magnesium (Mg) and Sulfur (S). Calcium attaches to the walls of plant tissues, stabilizing the cell wall and favoring cell wall formation. Calcium is also involved in cell growth and development. It improves plant vigor, activating the formation of roots and their growth.
Detailed explanation-2: -The flrst group, termed secondary nutrients, consists of calcium, magnesium, and sulfur, which are required by plants in the quantitites of the same order of magnitude as the major fertilizer elements of nitrogen, phosphorus, and potassium.
Detailed explanation-3: -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.
Detailed explanation-4: -Although sulfur is categorized as a secondary macronutrient behind nitrogen, potassium, and phosphorus, this does not imply it is less important.
