The water-holding capacity of a soil in a particular place depends on the depth of the soil, the
volume of pore-spaces, and the proportion of the voids that retain water against the pull of
gravity. In a sandy soil, there is relatively large total volume of pore space among the large
mineral particles, but the majority of the pores are so large that rainwater drains through most of
them, and relatively little is retained within the profile. In clayey soils, the opposite can be
expected. There may be a large proportion of small pore-spaces and while percolating rainwater
may enter partly under capillary action, but the water cannot drain out and can only be removed
by plant roots and/ or by slow evaporation into any air-filled spaces within the soil. In very
compact clay soils, both entry and exit of rainwater may be very slow (Indoria et al., 2017). The
presence of additional plant residue on the soil surface is one of the most prominent features of
conservation tillage systems when compared with conventional tillage. The surface residue
affects the absorption of solar radiation, and decreases the thermal admittance of the surface
relative to that of bare soil. Soil water storage at many semi-arid locations increased with
