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 case of nitrogen, the recycling of nitrogen from dead to living plants is often the only source of nitrogen in the soil. To make plants grow faster, what you need to do is supply the elements that the plants need in readily available forms. That is the goal of fertilizer.Most fertilizers supply just nitrogen, phosphorus and potassium because the other chemicals are needed in much lower quantities and are generally available in most soils. Nitrogen, phosphorus and potassium availability is the big limit to growth. Nitrogen, phosphorus, potassium (a.k.a. potash) - The three macronutrients and the three elements you find in most packaged fertilizers. 2  Sulfur, calcium, and magnesium-Secondary nutrients. 3  Boron, cobalt, copper, iron, manganese, molybdenum and zinc-Micronutrients.
