Answer
Nutrients are chemical elements that plants absorb from soil and atmosphere to grow and develop properly. Plants require 16 essential nutrients: three from air and water (carbon, hydrogen, oxygen), three primary macronutrients (nitrogen, phosphorus, potassium), three secondary macronutrients (calcium, magnesium, sulfur), and seven micronutrients (iron, manganese, zinc, copper, boron, molybdenum, chlorine).
