Detailed explanation-1: -The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.
Detailed explanation-2: -Nitrogen is used by plants for lots of leaf growth and good green color. Phosphorous is used by plants to help form new roots, make seeds, fruit and flowers. It’s also used by plants to help fight disease. Potassium helps plants make strong stems and keep growing fast.
Detailed explanation-3: -The 17 Essential Plant Elements include nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, chlorine, iron, manganese, zinc, copper, molybdenum, and nickel. The non-mineral essential plant elements include hydrogen, oxygen, and carbon.
Detailed explanation-4: -Nitrogen is needed for plant leaf and stem growth, using amino acids to build plant proteins. Phosphorus is used for root and seed production, and it is also essential for DNA replication to form cell walls and complete the reproduction cycle.
