Detailed explanation-1: -It is the water that is contained in the micropores of the soil, in the soil pore spaces precisely. This water, which composes the soil solution, is loosely held around the particles of soil. This form of water is the most available water form made available to plants for utilization.
Detailed explanation-2: -Capillary water is held in pores that are small enough to hold water against gravity, but not so tightly that roots cannot absorb it. This water occurs as a film around soil particles and in the pores between them and is the main source of plant moisture.
Detailed explanation-3: -What is capillarity of soil? In soils due to capillarity, water rises upto some distance above the water level and some part gets saturated fully above to that some other part gets partially saturated. Pressure at the water level is the atmospheric pressure and below to that is hydrostatic pressure.
