The field capacity is the water retained by a saturated soil after free drainage of surplus water to the ground water table but the water retained by a saturated soil after being centrifuged by a centrifugal force of 1000 times that of gravity is called________________?
Correct answer: A. Equivalent moisture
- A. Equivalent moisture
- B. Soil moisture
- C. Field moisture
- D. Available moisture
Explanation
Equivalent moisture is the water retained by a saturated soil after centrifuging it at about 1,000 times gravitational force. It is a laboratory estimate related to the soil's water-retention capacity and is distinct from field capacity, which follows natural drainage.
