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.
Plants require 14 essential nutrients of which the macronutrients nitrogen (N) and the minerals potassium (K), calcium (Ca), magnesium (Mg), phosphorous (P) and sulfur (S) are present in plant tissues in relatively large amounts [ 1 ].lant nutrition impacts on plant growth but also on most other living organisms since plants are the basis of many food chains. Animals and humans require all the minerals discussed above so their abundance and distribution in plants also affects our diets.
