Restrictive horizon definition

Restrictive horizon means a soil horizon that is capable of perching ground water or sewage effluent and that is brittle and strongly compacted or strongly cemented with iron, aluminum, silica, organic matter, or other compounds. Restrictive horizons may occur as fragipans, iron pans or organic pans, and are recognized by their resistance in excavation or in using a soil auger.

Restrictive horizon means a soil horizon that is capable of perching groundwater or effluent and

Restrictive horizon means a layer that significantly impedes movement of water through the subsurface. Layers that differ from overlying soil material enough to be considered restrictive horizons include (but are not limited to) volcanic bedrock, compacted soil, saprolite, and certain clayey soils.

Examples of Restrictive horizon in a sentence

• Restrictive horizon is often capable of perching ground water or wastewater effluent and is characterized by accumulation of finer soil particles (such as aluminum, clay, iron, silica, organic matter, or other compounds) or compaction due to heavy equipments.
