GENERAL GEOLOGY

Detailed explanation-1: -Soil texture is the relative percentages of sand, silt, and clay particles that make up the mineral (inorganic) fraction of soil (Fig. 3). Sand particles are the largest and range from 2.0 to 0.05 mm in diameter. Silt particles are smaller, ranging from 0.05 to 0.002 mm.

Detailed explanation-2: -Soil texture (such as loam, sandy loam or clay) refers to the proportion of sand, silt and clay sized particles that make up the mineral fraction of the soil. For example, light soil refers to a soil high in sand relative to clay, while heavy soils are made up largely of clay.

Detailed explanation-3: -6.0 Definition of soil texture Texture indicates the relative content of particles of various sizes, such as sand, silt and clay in the soil. Texture influences the ease with which soil can be worked, the amount of water and air it holds, and the rate at which water can enter and move through soil.

Detailed explanation-4: -The ideal mixture for agriculture is called loam and has roughly 40% sand, 40% silt and 20% clay. The texture of a soil determines its capacities and limitations. Many clay-rich soils are notorious for having poor drainage, high water retention, and substandard building surface potential.

Detailed explanation-5: -If we know the percentage of sand, silt, and clay in the soil, we can determine its texture. For example, if a soil is 40% sand, 30% silt, and 30% clay, the texture is clay loam.
