Detailed explanation-1: -The particle size analysis may be used to classify the soil sample into a specific textural class, such as a sand, silt, clay, loam, etc. Soil texture depends on its composition and the relative portions of clay, sand and silt.
Detailed explanation-2: -A soil’s texture depends on the proportion of sand, silt or clay it contains. For example, a soil described as a silt loam contains mainly silt but also will contain some sand and clay in smaller proportions.
Detailed explanation-3: -Particle size analysis (PSA) determines the relative amounts of sand, silt and clay in a soil. These size fractions are the mineral component of a soil and together determine soil texture.
Detailed explanation-4: -Soil texture refers to the size of the particles that make up the soil and depends on the proportion of sand, silt and clay-sized particles and organic matter in the soil.
Detailed explanation-5: -Silt particles are from 0.002 to 0.05 mm in diameter. Sand ranges from 0.05 to 2.0 mm. Particles larger than 2.0 mm are called gravel or stones. Most soils contain a mixture of sand, silt and clay in different proportions.
