Plant nutrition is an important aspect instrumental in the growth of plants. It gives an insight into the methods used to identify essential elements for the development of plants, the role of these elements, criteria to identify their essentiality, deficiency symptoms and mechanism of absorption of these elements. It also conveys the importance of nitrogen fixation.
Macro and micronutrients present in plants carry out essential processes such as cell-membrane permeability, osmotic concentration of cell sap and its maintenance, enzyme activity and so on.
Inadequate supply of essential elements can lead to critical concentration in plants. Elements are absorbed through a mechanism which involves isolated cells, tissues and organs.
Apart from other essential elements, nitrogen fixation also takes place in plants.
