what issues comes with surface flooding method of water application and why various irrigation application modes are adopted? Enlist the criteria preferring the good irrigation method.
Answers
Explanation:
Disadvantages of surface flooding method of water application
- This method involves high consumption of water which leads to drainage of water table and yields high cone of depression in the nearby area
- It generates high surface run-off leading to pollution of nearby water bodies and planes
- It is costly including the cost of machinery and water etc.
Adoption of various irrigation modes
- Various irrigation modes are adopted depending upon the crop requirement e.g. some crops needs more water than others, some crops needs constant source of water while others don't etc.
- Modes also vary depending upon the availability of water and resources
Criteria for a good irrigation method
- Method which uses least amount of water and generate least amount of surface run-off without compromising the need of the crops
- Method which is cost effective
- Method that results in better yield
