The A horizon is the top layer of the soil horizons or 'topsoil'.

"You are totally changing the soil horizons and forever eliminating any potential for future active agricultural use," he said.

Soil horizons are weakly developed, but a distinct topsoil horizon may be present.

Varying horizontal bands of colour in the soil often identify a specific soil horizon.

The small particles collect underneath the pavement surface, forming an Av soil horizon.

That is, neither soil horizons nor weathering zones underlie the biomantle.

Within the basal shell layer traces of an eroded soil horizon (paleosoil) were found.

Biologists believe that this layer of ash served as a soil horizon for native and invasive plants to colonize the area.

A vesicular, A soil horizon (Av) forms beneath the surface layer.

These soil scientists characterized soils based on soil horizons of the soil profile.

A soil horizon is a layer parallel to the soil surface, whose physical characteristics differ from the layers above and beneath.

A soil horizon accumulating leached and eluviated materials is referred to as a zone of illuviation.

The alteration and movement of materials within soil causes the formation of distinctive soil horizons.

Saprolites form in the lower zones of soil horizons and represent deep weathering of the bedrock surface.

The Downer has four soil horizons:

Black-tailed prairie dogs mix the soil horizons by raising soil from deeper layers to the surface.

Furthermore, tilling most certainly destroys soil horizons and hence disrupts the established flow of nutrients.

The process of removal of materials from geological or soil horizons is called eluviation or leaching.

Minimal soil horizons.
