The process involving the absorption, distribution and utilisation of mineral substances by the plants for their growth and development is called mineral nutrition.
Plants have the most efficient mechanisms for autotrophic mode of nutrition.
There are two types of nutrients.
The nutrients which are required by plants in large quantities are called macronutrients.
Example:
Carbon, Hydrogen, Oxygen, Nitrogen, Magnesium, Potassium etc.
The nutrients which are required by plants in small quantities are called micronutrients.
Example:
Iron, Molybdenum, Boron, Chlorine, Zinc etc.
Plants get nitrogen in the form of nitrates. Nitrogen metabolism is a major factor in stem and leaf growth. It helps plants with rapid growth, increasing seed and fruit production and improving the quality of leaf and crops.
Nitrogen is a major component of the following which are highly essential for plant life.
Too much nitrogen can delay flowering & fruiting.
Magnesium is present in the soil in water-soluble exchangeable and fixed form and it is present in many primary minerals.
It is essential for the synthesis of fats and the metabolism of Carbohydrates. It is also essential for fruit and nut formation & germination of seeds.
Deficiency of magnesium causes yellowing and wilting of leaves.
