Nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, boron, chlorine, iron, manganese, zinc, copper, molybdenum, and nickel are the essential mineral elements in the growth of the element plant.
- The macrominerals phosphorus, carbon, sodium, nitrogen, potassium, silicon, magnesium, hydrogen, calcium, oxygen, selenium, and sulphur are present in significant quantities in plant tissues.
- Microminerals or trace elements include iron, boron, nickel, manganese, copper, zinc, cobalt, chlorine, and molybdenum, which plants need in small quantities.
- Calcium is an important nutrient in plants. Plants require calcium for proper development of roots and shoots.
- Zinc is a cofactor of many key enzymes in biochemical pathways. Deficiency of zinc results in reduced crop yield.
- Copper is a component of chlorophyll and is thus important in the synthesis of carbohydrates. It is also essential for the formation of plant cell walls.
- Sodium is necessary only in small quantities and for some plants only.
