The correct answer is: C. Lift irrigation increases water logging.
Lift irrigation is a method of irrigation that uses pumps to lift water from a lower elevation to a higher elevation. This method is often used in areas where there is a shortage of water or where the water table is too low for gravity-fed irrigation.
However, lift irrigation can also lead to water logging, which is a condition in which the soil becomes saturated with water. This can cause a number of problems, including crop damage, soil erosion, and the loss of biodiversity.
In areas that are susceptible to water logging, it is important to use irrigation methods that do not contribute to the problem. Extensive irrigation, which is a method of irrigation that uses a large amount of water, should be avoided in these areas. Intensive irrigation, which is a method of irrigation that uses a small amount of water, can be used in these areas, but it is important to monitor the water table and to take steps to prevent water logging.
Here are some additional details about each option:
- A. Intensive irrigation should be avoided in areas susceptible to water logging. This is correct because intensive irrigation can lead to water logging.
- B. Extensive irrigation should be adopted in areas susceptible to water logging. This is incorrect because extensive irrigation can also lead to water logging.
- C. Lift irrigation increases water logging. This is correct because lift irrigation can lead to water logging.
- D. All of the above. This is also correct because all of the options are correct.
