The bearing capacity of a soil is defined as the capacity of the subsoil to support the load of the structure without yielding the bearing capacity of the soil depends upon the characteristics such as cohesion, friction, and unit weight. Soil texture is directly related to the percolation rate of a soil in the size of air spaces and surface area of the soil particles for example, sand is the largest of the soil particles therefore it.

By knowing soil structure, the moisture content of the soil mass can be worked on, which is equally important for engineering and agricultural works color of soil generally speaking, soils are classified as dark and light colored soils.
These bound nutrients interact with soil water to buffer the soil solution composition (attenuate changes in the soil solution) as soils wet up or dry out, as plants take up nutrients, as salts are leached, or as acids or alkalis are added. Compaction of soil is an important process, as it helps it of achieve certain physical properties necessary for its proper behaviour under loading: for example proper compaction of an earthen dam or a highway embankment reduces the chances of its settlement, increases the shear strength of the soil .
