Detailed explanation-1: -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. These are either taken up as a gas or water.
Detailed explanation-2: -Phosphorous, carbon, sodium, nitrogen, potassium, silicon, magnesium, hydrogen, calcium, oxygen, selenium and sulphur are known as macrominerals and are generally required in large amounts by the plant tissues.
Detailed explanation-3: -Plants need nutrients Nitrogen, phosphorus, and potassium are needed in larger amounts than other nutrients; they are considered primary macronutrients. Secondary macronutrients include sulfur, calcium, and magnesium. Micronutrients such as iron and copper are necessary in much smaller amounts.
