Irrigation are necessary because :

1. Irrigation before ploughing the fields make the soil soft due to which the ploughing of fields becomes easier
2. Irrigation is necessary to provide moisture for the germination of seeds. This is because seeds don't grow in dry soil.
3. Irrigation is necessary to maintain the moisture of the soil for healthy crop growth so as to get good yield
4. Irrigation is necessary for the absorption of nutrients elements by the plants from the soil. The irrigation water dissolves the nutrients present in the soil to form a solution. This solution of nutrients is then absorbed by the roots for the development of plants.
5. Water supplied to the crops during the irrigation protects the crop plants from hot air currents as well as frost.
