Detailed explanation-1: -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-2: -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. Clay particles are smaller than 0.002 mm.
Detailed explanation-3: -Sand, silt, clay, and organic matter particles in a soil combine with one another to form larger particles of various shapes and sizes and are often referred to as aggregates, or clus-ters. Soil structure is the arrangement of the soil particles into aggregates of various sizes and shapes.
