How does soil particles size affect soil?

Answer 1

soil particle designate the nomenclature of soil such as gravel, sand, silt & clay and further its engineering properties

The size and shape of soil particles determine the way they settle and stack, and this arrangement affects soil drainage, the mix of microorganisms that can live in the soil, and the types of plants that can grow there.

Coarse soil particles like sand tend to stack like marbles at the top of the soil horizon, while finer soil particles like the flat, pancake-shaped particles of clay settle into a dense layer deeper in the soil profile. Blocky silt particles settle in between, although they can sometimes form hard surface crusts that make water run off, instead of filtering down into the soil.

Answer 2

Soil particle size affects soil by influencing its ability to retain water, nutrients, and air. Larger particles, such as sand, create large pores which allow for better drainage but lower water and nutrient retention. Smaller particles, like clay, create small pores which hold water and nutrients well but may become compacted and restrict air flow. Ideal soil structure consists of a balance of particle sizes for optimal plant growth.
