Hydnc soils fbrm �ahen soils are saturated, <br />(looded, or ponded long enough during thc gro�ving scason to develop anaerobic conditions in the <br />upper part. Indicators of hydric soil arc £om�ed when anaerobic biological activities result in distinct <br />soil colors. Un:ler these conditions, low chroma colors and monles of bright color typically form <br />within the soil matrix. OU�cr indicators indude high organic matter content in the surface horizon, <br />odors of reduced sulfur, and staining by organic matter in die suUswface horizon. <br />CES cxamincd soils by digging sample pits to a depth of 18 inches or more to obsen�e soil profiles <br />and determine hydrologic conditions. iviunsell color charts (Greytag Macbeth 1994) were used to <br />dcscribc soil colors. <br />2.3.3 }Ivdrnlos�' <br />CES cxamincd arcas fur cvidcncc of hydrulo��y.
