Describe the role of different elements in plant nutrition• Carbon• Hydrogen• Oxygen• Nitrogen• Phosphorus• Magnesium• Iron• Potassium
• All of these elements plants need for synthesis of organic molecules.
Deficiency of elements• Can cause serious diseases with clear symptoms.

Phosphorus DeficiencyCauses stunted growth of roots
Phosphorus Deficiency poor growthFruits are small and acid tasting.
