WebThe vertical section of the soil from the surface to the parent rock is called the soil profile. The soil profile consists of a number of horizontal layers called soil horizons. They are designated by the letters O, A, E, C, B and R horizons. The soil horizons can be differentiated due to the difference in colour, texture, structure, and ... WebThe surface soil horizon(s) or topsoil (the Ap or A+ E horizons) is often coarser than the subsoil layer and contains more organic matter than the other soil layers. The organic matter imparts a grayish, dark-brownish, or black color to the topsoil. Soils that are high in organic matter usually have dark surface colors.

Of 22 ectomycorrhizal fungal taxa identified in a coniferous forest soil, 2 taxa were restricted to the organic horizon, whereas 11 were found only in the mineral soil ( Rosling et al., 2003 ).
