Plants prepare their food by the process of photosynthesis. In this process, plants use sunlight, carbon dioxide & water. Therefore, photosynthesis covers 95% of the plant’s food requirement. Plants require oxygen for respiration, just like we do. However, to stay healthy plants need basic nutrients, supplementary nutrients & micronutrients.

Basic nutrients: Nitrogen (N), Phosphorus (P), and Potassium (K) are 3 major essential nutrients that are provided via soil.

Supplementary nutrients: Calcium, Magnesium & sulphur are also essential nutrients, but are required in a moderate amount in the soil.

Micronutrients: Iron, Boron, Copper, Zinc, Molybdenum, & chlorine are mineral nutrients that are required in a very less amount in the soil. These play a key role in plant growth.
