Ground-Water Levels and Soil Characteristics in a Forested Typic Glossaqualf

Informally Refereed

Abstract

The presence of impermeable layers can affect the development of a soil and its water regime. In a forested Typic Glossaqualf in southwest Louisiana, moisture, density, and piezometer measurements revealed an impermeable layer of soil between about 1.8 and 2.8 m below the surface. A high proportion of very fine sand and development of platy structure appeared related to a low proportion of drainable pores in the layer. Glossic characteristics were well developed in the B horizon and were associated with an intermittet perched water table but disappeared as moisture content became more uniform at greater depths. An auger hole that extended through the impermeable layer indicated, during dry periods, the pressure variations of a deep water source rather than a continuous water table.
