The soil water that is readily available for absorption by plant roots is called capillary water. Capillary water is held in the soil by capillary forces, which are the forces that allow water to move through narrow spaces, such as the tiny spaces between soil particles. This type of water is easily accessed by plant roots and is essential for plant growth and survival. Gravitational water, on the other hand, is water that drains out of the soil due to gravity and is not available to plants. Hygroscopic water is water that is held tightly to soil particles and is also not available to plants. Superfluous water is excess water that can lead to waterlogging and soil erosion, and is also not available to plants. Therefore, capillary water is the type of soil water that is most important for plant growth and is readily available for absorption by plant roots.
