Why does clay hold more water than sandy soil?

Soil on the other hand not only can capture some water by adsorbtion in the interstices, but because soil contains organic [plant] matter which can absorb water, soil can thus "hold" more water. AS far as I know and I'm no expert by any means, sand would not absorb water as much as soil in general. read more

For example, a coarse soil is a sand or loamy sand, a medium soil is a loam, silt loam, or silt, and a fine soil is a sandy clay, silty clay, or clay. Soil structure refers to the ... or overall pore space. Water can be held tighter in small pores than in large ones, so fine soils can hold more water than coarse soils. read more

√ clay soil which has finer particle size ,inturn which has a more surface area. √In case of this soil type which has more porasity (spaces exist between soil particles) √Thats why clay soil has more water holding capacity than other type of soils. read more

Clay soil is also harder to cultivate than other soil types because it is naturally denser. Because the particles in clay soil swell and shrink as the soil becomes wet and then dries, clay soil can cultivate itself. In turn, sandy soil is simple to work, and loam soil is moderately difficult to work. read more
