Answer Details

The water which rises above the water table in the soil and is held in fine medium pores between soil particles by surface tension is called "capillary water". Capillary water is able to rise above the water table because of the combined forces of adhesion (attraction between water and soil particles) and cohesion (attraction between water molecules). These forces enable water to move upwards through narrow pores against the force of gravity. In simpler terms, imagine a sponge dipped in water. The water rises up the sponge through capillary action because the tiny spaces between the sponge's fibers are able to hold the water due to surface tension. Similarly, in soil, the capillary action causes water to move upwards against gravity and be held in the spaces between soil particles. This capillary water is important for plant growth as it is the water that is available to plants for uptake through their roots.
