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: -Sand soil has excellent drainage properties because of its coarse and large texture. Nonetheless, you cannot use sand alone in the garden because it will drain all the water and wash away nutrients in the ground. Also, a few flood-tolerant plants require fine textured soil which can hold water.
Detailed explanation-3: -Large particles that are loosely spaced, such as sand or silt, allow water to move through the soil and drain quickly. Types of soil that drain most readily include sandy, silt and a mixture of sand, silt and clay called loam.
Detailed explanation-4: -Sand is the largest particle size. Sandy soils feel gritty. They tend to be free draining so they do not get waterlogged.
Detailed explanation-5: -Silt. Like sand, silt particles are relatively large and leave gaps, so water can flow through easily.
