A Field Tool Visually Indicates Hydric Soil Conditions

Indicator of Reduction in Soils (IRIS) tubes visually reflect current hydric soil conditions caused by anaerobic and reducing processes. This technology provides the user with a device that is easily installed and simple to visually interpret in the field.

IRIS devices can identify hydric soils in wetlands, investigate depth of saturation in soils, identify failed septic systems, and qualitatively analyze soil organic carbon content.

Adopted as National Hydric Soil TECHNICAL STANDARD

The National Technical Committee for Hydric Soils has adopted IRIS tubes as part of the Hydic Soil Technical Standard (HSTS) for identifying anaerobic conditions in soils.

Reliable, robust, and easy to use!
