functions of different minerals

1. Functions Of Minerals and Methods of
Studying Plant Nutrition
Presented by: Danyal La ghari

2. Mineral Nutrition:
is defined as the naturally occurring inorganic
nutrient found in the soil and food that is essential for the proper
functioning of plant body. Minerals are vital elements necessary
for the body.
• Following are the some essential minerals of plants.
• C, H, N, S, K, P, Mg, Fe, Mn, Zn, Cu, And Mo these are the some
essential elements for many plants.

3. The essential elements can be classified into two groups.
1) Macronutrients:
The essential elements which are required by plants in
large amount. Following are the functions of some Macronutrients.
Nitrogen (N)
• Nitrogen is the most important element. It is the
important constituent of proteins, nucleic acids,
vitamins, Coenzymes.
• As it is the part nucleic acids so its also important for
growth, metabolism, reproduction.

4. Phosphorus (P)
• Phosphorus play main role in the formation of nucleic acids,
phospholipids, coenzymes, NADP, NAD, ATP.
• Through coenzymes NAD, NADP, and ATP it plays role in
photosynthesis and respiration.
• Phosphorous promotes healthy growth of roots and fruit
ripening.

5. Sulphur (S)
• It is an important constituent of amino acids like cysteine and
methionine.
• It is the also constituent of vitamins biotin, thiamine, and
coenzyme A.
• Disulphide linkages help to stablize the structure of protien.
• Sulphur also helps in root development.

6. Potassium (K)
• Potassium plays important role in the opening and closing of
stomata.
• It act as activator many enzymes.
• It determines anion and cation balance in cell.
• It is involved in protein synthesis.

7. Magnesium (Mg)
• It is an important constituent of chlorophylls.
• It activates the enzyme in respiration, photosynthesis, DNA
and RNA synthesis.
• It act as phosphorus carrier in plant.

8. Calcium (Ca)
• It is the important constituent of middle lamella in cell wall.
• It act as second messenger in metabolic regulation.
• It may be an activator of many enzymes.
• It is essential for the formation of cell memebranes.

9. 2) Micronutrients:
Micronutrients also knowns as trace elements.
These are the essential nutrients which are required by plants in
very small amount.
Iron (Fe)
• It is the constituent of ferredoxin and cytochromes
• It is involved in the electron transport chain.
• It activates catalase.
• It helps in the formation of chlorophyll.

10. zinc
• It is involved in the biosynthesis of growth hormones of
plants like auxins, Indole -3- Acetic acid(IAA)
• It act as an enzyme activator of many enzymes like
carbonic anhydrolase.

11. Methods of studying plant nutrition
Hydroponics: It is the method of growing plant without
soil. Following are the different type of hydroponics.
1. The wick system:
• This system belongs to passive group
which means I does not require
sophisticated or equipment like motors
and pumps.
• His system require a container with
plant, a reservoir, Several long strips of
suitable wicking material, string, or
rope.
• A good hydroponic growing media
like hydroton or perlite.
• A suitable nutrient solution.

12. 2. The drip system: A drip system is an
active hydroponic system. This means that it
uses a pump to feed your plants with nutrients
and water regularly. It is also called trickle,
or micro irrigation system.

13. 3. Ebb and flow system:
Ebb and Flow, or Flood
and Drain is a system involves the periodic
flooding and draining of the nutrient
solutions. Basically, there are two phases of its
operation. The Flood is when the water and
nutrients flow the growing areas, flowing over
the plants’ roots. The drain is when the water
drains back to the reservoir. These two actions
take turn continuously, and hence their name.
