Macronutrients are required by the plant in large quantities for basic plant growth and development. The macronutrients include: nitrogen, phosphorus and potassium. Secondary nutrients are required in moderate amounts and are less likely to limit crop growth. These nutrients include: calcium, magnesium and sulphur. 1  Nitrogen. 2  Phosphorus. 3  Potassium. 4  Calcium. 5  Magnesium. 6  Sulfur.
In the leaves of a plant is a substance called chlorophyll. Chlorophyll makes leaves green. It also traps the energy from the sun so the plant can use it. When plants take carbon dioxide from the air, they release oxygen. Animals use this oxygen to grow. We release carbon dioxide, which the plants use. Plants also need minerals from the soil to grow. Nitrogen helps them grow and make leaves. Phosphorus helps grow strong roots. Potassium helps the plant make fruit and it keeps them healthy. Plants need large amounts of nitrogen, phosphorus and potassium. The soil doesnât always have enough of these nutrients. Gardeners use fertilizer to give plants more nutrients. Fertilizers are sort of like vitamins for plants.
