Detailed explanation-1: -Six of these nutrients are needed in large quantities. These six essential nutrients are nitrogen, phosphorus, potassium, magnesium, sulfur and calcium.
Detailed explanation-2: -Final Answer:-Minerals known to be required in large amounts for plant growth include Phosphorus, Potassium, Sulphur, and Calcium.
Detailed explanation-3: -Calcium, phosphorus, and magnesium are required in relatively large amounts and are designated as macrominerals. These are discussed in this chapter. Minerals needed in smaller amounts are called trace elements; these are discussed in Chapter 14.
Detailed explanation-4: -Nitrogen and phosphorus are among the elements considered most limiting to plant growth and productivity because they are often present in small quantities locally or are present in a form that cannot be used by the plant.
