Plants take up essential elements from the soil through their roots and from the air through their leaves. Plants nutrient elements are divided into two parts: Macronutrients and Micronutrients.
Macronutrients: Comparatively they are needed in large quantities. 10 minerals are macro nutrients, they are Nitrogen (N), Potassium (K), Calcium (Ca), Iron (Fe), Magnesium (Mg), Carbon (C), Hydrogen (H), Oxygen (0), Phosphorus (P), and Sulphur (S).
These 10 macronutrients can easily be remembered by the following sentence -Mg.K. CaFe for Nice CHOPS = Mg.K Cafe for good chops. Here Mg for Magnesium, K for Potassium, CaFe for Calcium and Iron, CHOPS for Carbon, Hydrogen, Oxygen, Phosphorus and Sulphur.
Micronutrients: They are needed in minute amount. Following six elements are micronutrients: Zinc (Zn), Manganese (Mn), Molybdenum (Mo), Boron (Bo), Copper (Cu), and Chlorine (Cl).
Beside these Sodium (Na), Aluminum (Al). Silicon (Si). and Cobalt Co) are also needed.
