Mineral Nutrition – Notes
Essential Nutrients of Plants
Nutrition is the process of absorption of various minerals ions for growth.
The elements essential for plant growth are further divided into macronutrients and micronutrients.
The elements that are required by a plant in large amounts are called macronutrients.
The elements that are required in minute quantities are called micronutrients or trace elements.
Macronutrients of Plants
Elements that are required by plants in large amounts are called macronutrients.
Elements like carbon, hydrogen, oxygen, nitrogen, phosphorus, sulphur, potassium, calcium and magnesium are micronutrients.
The concentration of essential elements below which plant growth is retarded is termed as critical concentration.
The deficiency of different elements causes different symptoms in a plant.
Micronutrients of Plants
The elements that are required in minute quantities by plants such as iron, manganese, copper, molybdenum, zinc, boron, chlorine and nickel are called micronutrients or trace elements.
