Main Inorganic Nutrients

There are two types of main inorganic nutrients which are macronutrients and micronutrients.

Function macronutrients and micronutrients.

Macronutrient	Function
Carbon, hydrogen, oxygen	Synthesis main organic compounds such as carbohydrate, protein, lipis and nucleic acid
Nitrogen	Synthesis of chlorophyll, amino acid and nucleic acids
Phosphorus	Synthesis nucleic acids, ATP and plasma membrane Impotant in photosysnthesis
Potassium	Synthesis of protein Cofactors for enzymes
Calcium	Lamella component Formation of spindle fibres
Magnesium	Synthesis of chlorophyll and activate plant enzyme
Sulphur	Synthesis of amino acids, nucleic acids and vitamins

Mikronutrien	Function
Chlorine	Control osmotic pressure and ion balance
Iron	Synthesis chlorophyll
Manganese	activates enzymes in photosynthesis
Boron	Cell division in meristamatic tissue
Zinc	Synthesis auxin
Copper	Synthesis chlorophyll Activates enzymes
Nickel	Certain enzyme components in metabolism Involved in nitrogen binding
Molybdenum	Involved in carbon fixation

Deficiences in the nutrients

Macronutrients	Deficiency effects
Carbon, hydrogen, oxygen	Death of plants
Nitrogen	Chlorophyll ann stunted growth
Phosphorus	Poor root growth Red or purple spots on old leaves
Potassium	Premature death of plants Yellow-edged leaves
CAlcium	Stunted growth Formation of unhealthy leaves
Magnesium	Chlorosis and red spots on leaf surface
Sulphur	Chlorosis

Micronutrients	Deficiency effects
Chlorin	Chlorosis and wilting of young leaves
Iron	Young leaves becomes yellowish
Manganese	Brown spots between veins
Boron	Death of shoot tips
Zinc	Stunted growth
Copper	Chlorosis and red spot on leaves
Nickel	Stunted growth and chlorosis Unhealthy growth of shoots, tips of shoot is dead
Molybdenum	Pale green leaves and reduction in cr
