GENERAL KNOWLEDGE

Detailed explanation-1: -Sandy soil is made of sand particles that are rough in texture. This prevents them from sticking tightly together. The space between sand particles is large for water to flow through it. Hence sandy soil drains faster than other types of soil.

Detailed explanation-2: -Soils with large pores such as sandy soils tend to conduct water more easily than soils with smaller pores such as clay soils. Thus sands have higher saturated conductivity values than clays (Examples).

Detailed explanation-3: -Sandy soils have less pore volume than silt or clay soils. Note that the water penetrates more rapidly and more deeply in the sandy soil than in either the silt or clay soils. This is because sandy soils have larger pores that absorb water faster, and hold less water per unit of depth.

Detailed explanation-4: -Sand allows water to drain through it more easily than silt and clay so more water should have drained through the sandy soil than the potting soil.
