Capillary action refers to the movement of water within soil or other porous materials due to the forces of adhesion, cohesion, and surface tension. In soil, capillary action enables water to move upward through small pores, allowing plants to access moisture from below the surface. This process plays a key role in plant hydration, especially in dry conditions, as it helps distribute water from wetter to drier areas.
