Answer :
Soil texture is determined by the mix of sand, silt, and clay particles, with sand being the coarsest and clay the smallest. The texture affects the soil's water retention and nutrient availability.
The texture of topsoil is determined by the relative proportions of sand, silt, and clay size particles in the soil. These particles range from coarse to fine, with sand being the coarsest, followed by silt, and then clay, which is the smallest particle size. This mixture defines the soil's physical characteristics and influences its behavior in terms of water retention, drainage, and nutrient availability.
Soils dominated by clay are referred to as fine-textured soils, while those with a predominance of larger particles like sand are known as coarse-textured soils. Soil scientists utilize a soil texture triangle to classify the texture class of the soil, which can influence the soil's water-holding capacity (WHC) and nutrient availability.
