Plinthite is a subsurface soil feature that perches water during periods of excess soil moisture. Water movement in a plinthic soil in the Southern Coastal Plain was monitored over an 8-week period using a bromide tracer. Field investigations conducted on a Tifton loamy sand (Plinthic Paleudult) with a 4% slope indicate that much subsurface flow under saturated conditions occurs above and within plinthite. Results also indicate that movement through the plinthic horizons is slow and occurs primarily in low-chroma bodies associated with plinthite that are interconnected in dendritic patterns. Water does not readily penetrate the dense plinthic bodies.
