Question

The maximum amount of water that soil can hold is called ___

• A. Wilting point
• B. Water potential
• C. Field capacity
• D. Osmotic potential

Answer 1

The correct option is C Field capacity

The maximum amount of water that a given soil can retain is called field capacity.
The lower limit of water availability in soil below which a plant wilts is known as wilting point.
Water potential is a measure of the potential energy of water, that is the difference between the potential energy in a given water sample and pure water.
Osmotic potential is the potential of water molecules to move from a hypotonic solution to a hypertonic solution across a semi-permeable membrane.
