Plants require nutrients for proper growth and development. There are 16 elements which are required for plant and are termed as essential elements. They are as follows:
Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N), Phosphorus (P), Sulphur (S), Potassium (K), Magnesium (Mg), Calcium (Ca), Iron (Fe), Copper (Cu), Boron (B), Zinc (Zn), Manganese (Mn), Molybdenum (Mo) and Chlorine (Cl).
The essential elements are categorised into 2 groups,
- Macro- nutrients: These are required by plants in large quantities. eg, C, H, O, N, S, P, K, Ca and Mg.
- Micro- nutrients: These are required by plants in very small quantities. eg, Fe, Cu, B, Mn, Ni, Mo and Cl.
