The correct answer is D. All the above.
A land is said to be water-logged if its soil pores within a depth of 40 cm are saturated, a depth of 50 cm are saturated, and the root zone of the crops are saturated.
Waterlogging occurs when the soil pores are filled with water and there is not enough air space for the roots of plants to grow. This can happen when there is too much rain, when there is irrigation without proper drainage, or when the soil is compacted.
Waterlogged soil can cause a number of problems, including:
- Reduced crop yields
- Increased risk of plant diseases
- Soil erosion
- Damage to foundations and other structures
To prevent waterlogging, it is important to have proper drainage in place. This can be done by installing drainage ditches, tile drains, or by using a raised bed. It is also important to avoid over-irrigation and to keep the soil loose and well-drained.
