Week 4: Essential mineral elements, role and deficiency symptoms of macronutrients.
The elements which are required for the normal and healthy life of a plant are called essential elements.
Only sixteen elements which are divided into two categories. Viz
- Macronutrients (major elements)
- Micronutrients (trace elements)
Macronutrients include N, P, Ca, K, O, C, F, S and Mg.
Micronutrients include Fe, Mn, B, Cu, Zn, Mo and Cl.
For example N function is, it is part of protein, chlorophyll, nucleic acid while its deficiency syndromes are stunted growth, leaf chlorosis, leaf sheading, poor flowering and fruits.
