Thoughn they are in village they have practical knowledge about nutrients without knowing about what is it?. They follow others and put fertilizers and all without raising questions. So I explained about the essential nutrients and differentiate them into macro and micro and make them understand. I give here what I taught them in my awareness camp.

Macro nutrients From AIR Non mineral nutrients Oxygen (O) Carbon (C) Hydrogen (H) From SOIL Primary nutrients Nitrogen (N) Phosphorus (P) Potassium (K) Secondary nutrients Calcium (Ca) Magnesium (Mg) Sulfur (S) Micro nutrients From SOIL Boron (B) Chlorine (Cl) Copper (Cu) Iron (Fe) Manganese (Mn) Molybdenum (Mo) Zinc (Zn) and so on |
