The B horizon has a lower organic matter content than than the topsoil and often has more clay. A mass of rock such as granite basalt quartzite limestone or sandstone that forms the parent material for some soils if the bedrock is close enough to the surface to weather. Surface litter is termed the A horizon.

O-horizon surface littermainly partially decaying organic matter A-horizon Topsoil mainly contains organic matter living organisms inorganic minerals. This is a weathered layer that contains an accumulation of humus decomposed dark-coloured carbon-rich matter and microbial biomass that is mixed with small-grained minerals to form aggregate structures. Unlike the horizon above this horizon does not comprise rocks or boulders but instead is made of continuous mass of bedrock.

Each soil horizon was labeled with a four-letter code representing the site core and basal depth of the sample. In horizon E the humus that formed in the previous horizon is now lacking nutrients and various minerals such as iron and aluminum. The ____-horizon of a soil contains no organic material and is composed of parent material.
