Question

Minerals known to be required in large amounts for plant growth include :

• A. Phosphorus, Potassium, Sulphur, calcium
• B. Potassium, phosphorus selenium, boron
• C. Magnesium, Sulphur, iron, zinc
  
• D. Calcium, magnesium, manganese, copper
  

Answer 1

The correct option is A Phosphorus, Potassium, Sulphur, calcium

The primary macronutrients: nitrogen (N), phosphorous (P), potassium (K); the three secondary macronutrients: calcium (Ca), sulphur (S), magnesium (Mg); the micronutrients/trace minerals: boron (B), chlorine (Cl), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), molybdenum (Mo), nickel (Ni).

Plants need thirteen different nutrients from the soil in order to fully develop. Six of these nutrients are needed in large quantities. These six essential nutrients are nitrogen, phosphorus, potassium, magnesium, sulfur and calcium.
