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 that the soil can hold after excess water has drained away and the soil particles have become saturated. This water is held in the soil by a combination of gravity and the attraction between water molecules and soil particles. In other words, field capacity is the point at which the soil is neither too wet nor too dry, and it is the maximum amount of water that can be stored in the soil and still be available for plants to use.
