Field Capacity and Soil Water Tension
Field capacity is defined as the amount of water held in the soil after excess water has drained away and the rate of downward movement of water has decreased to a negligible amount. At this point, the soil is considered to be fully saturated and the soil pores are filled with water.
Soil water tension is the measure of the force required to remove water from the soil. It is also known as soil water potential or soil suction. The tension is measured in units of pressure, such as atmospheres (atm), bars (bar), or pascals (Pa).
At field capacity, water is held in most of the soils at a tension of 1/3 atmosphere (1/3 atm). This means that a force of 1/3 atm is required to remove the water from the soil. The soil water tension at field capacity is a critical parameter in plant growth, as it determines the availability of water to the plants.
Other Options:
Option A: 15 atmospheres is too high for field capacity tension. This tension is usually found in dry soils.
Option B: At zero atmosphere, the soil would be completely saturated and there would be no air in the soil pores. This condition is not field capacity.
Option D: 1 atmosphere is too high for field capacity tension. This tension is usually found in well-drained soils.
