Soil horizon can be defined as layer of soil lying parallel to the surface of earth. The soil horizons differ on the basis of type of minerals particles present in them, fertility, color and structural property of soil. The soil horizons are formed due to the weathering process of parent rocks. The weathering causes the aggregation of the large, small particles and sediments in distinct layers forming horizon.

The A horizon is near the surface or sub-surface regions of the soil. This consists of highly weathered rock particles in the form of sediments. The soil particles in the horizon are smaller and finer than other horizon.
