Consider the following zones: Saturation zone Capillary zone Intermedi...
The earth crust according to the existence of water is mainly divided into two zones:
  • Zone of Rock Fracture
  • Zone of Rock Flowage
Zone of Rock Fracture is further divided into two zones:
  • Zone of Aeration 
  • Zone of Saturation
Zone of Aeration is further divided into three zones:
  • Root soil water zone
  • Intermediate zone
  • Capillary water zone

Hence, the saturation zone does not come under the zone of aeration.

Consider the following zones: Saturation zone Capillary zone Intermedi...
Zone of Aeration in the Soil Profile:
The zone of aeration is the part of the soil profile that contains both air and water. It is located above the water table and below the ground surface. This zone plays a crucial role in plant growth as it provides oxygen to the roots and allows for the movement of water and nutrients.

Explanation:

1. Saturation Zone:
- The saturation zone is the area below the water table where all the pores in the soil are filled with water.
- This zone is not a part of the zone of aeration as it does not contain any air.

2. Capillary Zone:
- The capillary zone is the region above the water table where water is held in the soil by capillary action.
- This zone is also not part of the zone of aeration as it contains water but limited air.

3. Intermediate Zone:
- The intermediate zone is the transition area between the capillary and saturation zones.
- This zone is not directly related to the zone of aeration as it does not primarily consist of air.

4. Soil Water Zone:
- The soil water zone includes all the zones mentioned above and represents the total moisture content in the soil.
- This zone includes the capillary, saturation, and intermediate zones, but it does not specifically refer to the zone of aeration.
Therefore, the correct answer is option 'D' - 1 only, as the saturation zone and capillary zone do not relate to the zone of aeration in the soil profile.
