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.
The minerals and water become building blocks that the plant uses during photosynthesis to generate food. Plants use both macronutrients and micronutrients. Macronutrients that plants need in order to make their own food include phosphorous, potassium, nitrogen, sulfur, magnesium and calcium. These are the larger minerals that tend to get leached from the soil first. Micronutrients are still essential for photosynthesis, but plants need them in smaller amounts.
