Detalhes da Resposta

The type of water left in the soil after excess water has been drained off, following heavy rainfall is known as field capacity. Field capacity refers to the amount of water held in the soil after excess water has drained away due to the force of gravity. When it rains heavily, the soil initially absorbs the water until it becomes saturated. The excess water then drains away, leaving behind the water that is held in the soil by capillary forces. This water is held in the soil pores and is available to plants for their use. The amount of water held in the soil at field capacity depends on the soil type, structure, and porosity. In summary, field capacity refers to the amount of water held in the soil after excess water has drained away, and it is the water that is available to plants for their use.
