• Nutrients can be divided according to quantities required by plants, which are macronutrients and micronutrients.
• Main inorganic nutrients:
  • Macronutrients:
    • Carbon (C)
    • Calsium (Ca)
    • Hidrogen (H)
    • Magnesium (Mg)
    • Oxsigen (O)
    • Phosphorus (P)
    • Nitrogen (N)
    • Sulphur (S)
    • Potassium (K)
  • Micronutrients:
    • Clorin (Cl)
    • Zinc (Zn)
    • Iron (Fe)
    • Copper (Cu)
    • Manganese (Mn) 
    • Nickel (Ni)
    • Boron (B)
    • Molybdenum (Mo)
• Three main macronutrients, which are carbon, hydrogen and oxygen, can be obtained easily from air and water from the soil.
• These nutrients make up most of the dry mass of plants.
• Therefore, the lack of these nutrients is rarely experienced by plants.
• The remaining nutrients are taken in the form of mineral salts which are dissolved in the soil through fertilisation.

• Synthesis main organic compounds such as carbohydrate, protein, lipis and nucleic acid .

• Death of plants.

• Synthesis of chlorophyll, amino acid and nucleic acids.

• Chlorosis.
• Stunted growth.

• Synthesises nucleic acids, adenosine triphosphate (ATP) and phospholipids in plasma membrane.
• Act as coenzymes in photosynthesis and respiration.

• Poor root growth.
• Red or purple spots on old leaves.

.

• Synthesis of protein.
• Cofactors for enzymes.

• Premature death of plants.
• Yellow-edged leaves.

• Main component of middle lamella, cell wall and spindle fibres during cell division.

• Stunted growth.
• Formation of unhealthy leaves.

• Synthesis of chlorophyll and activate plant enzyme.

• Chlorosis and red spots on leaf surface.

• Components of a few amino acids.
• One of vitamin B constituents and a few types of coenzymes.

• Chlorosis.

• Control osmotic pressure and ion balance.

• Chlorosis.
• Wilting of young leaves.

• Synthesis chlorophyll.
• Important in the growth of young plants.

• Young leaves become yellowish.

• Activates photosynthetic enzymes.
• Important for cell respiration and nitrogen metabolism.

• Network of dark green leaf veins with a background of light green.
• Light brown or grey spots in between leaf veins.

• Helps the roots in calcium ion uptake and sucrose translocation.
• Involves in carbohydrate metabolism and helps in germination of pollen.

• Death of terminal buds and abnormal growth.
• Leaves become thicker, rolled up and fragile.

• Synthesis of auxin (growth hormone).
• As a cofactor in carbohydrate metabolism.

• Stunted growth .
• Leaf surfaces become spotted with chlorosis parts.

• Synthesis chlorophyll.
• Activates enzymes.

• Death of young shoot apex.
• Brown spots on terminal leaves.
• Plants become stunted.

• A component of plant enzymes.
• Involved in the breakdown of urea to become ammonia which can be used by plants.

• Stunted growth.
• Reduces crop production.
• Burnt effect at the end of leaves due to urea accumulation.

• Involves in nitrogen fixation and nitrate reduction during protein synthesis.

• Chlorosis in between matured leaf veins.
• Leaf colour becomes pale green.
• Reduces crop production.

• A culture solution is used to study the importance of nutrients for plant growth.
• A culture solution known as Knop’s solution, contains all nutrients including trace elements needed by healthy plants.
• A complete culture solution was prepared by a chemist named Wilhelm Knop in 1859.
