Soil Moisture and its Available Capacity
Soil moisture is the amount of water present in the soil. It is important for plant growth and is affected by various factors such as climate, soil type, vegetation, and land use.
The available moisture of the soil is defined as the water that is available for plant growth, and it is equal to the difference between the field capacity and the permanent wilting point within the root zone of plants.
Field Capacity
Field capacity is the maximum amount of water that soil can hold against the force of gravity after it has been saturated and excess water has drained away. At field capacity, the soil is moist but not saturated, and plant roots can easily extract water from the soil.
Permanent Wilting Point
The permanent wilting point is the point at which plants can no longer extract water from the soil, and they wilt and eventually die. At this point, the soil is completely dry, and water is held tightly by soil particles and unavailable for plant uptake.
Available Moisture
The available moisture is the difference between the field capacity and the permanent wilting point within the root zone of plants. It represents the amount of water that plants can use for growth and development.
Importance of Available Moisture
The available moisture is an important factor in determining plant growth and yield. If the soil moisture level is too low, plants will wilt and eventually die. If the soil moisture level is too high, plants may suffer from root rot and other diseases.
Therefore, it is important to maintain soil moisture at an optimal level for plant growth by using irrigation, mulching, and other management practices.

Moisture equivalent is defined as the percentage of water which a soil can retain in opposition to a centrifugal force 1000 times that of gravity. It is measured by saturating sample of soil 1 cm thick, and subjecting it to a centrifugal force of 1000 times gravity for 30 min.
