Abstract/Contents:"Most turfgrass thatch sorption studies have examined the sorptive characteristics of single turfgrass species using traditional batch techniques. In this study, the sorptive capabilities of the thatch of two turfgrass species were determined using a modified batch/flow technique that minimized disrupting thatch organic matter. Dicamba adsorption to zoysia (Zoysia japonica Steud.) and hard fescue (Festuca longifolia Thuill) thatch was compared with soil below each thatch layer for solution residence times ranging from 15 minutes to 24 hours. Desorption of dicamba from soil and zoysia thatch was also examined. Dicamba adsorption was markedly influenced by solution residence time and turfgrass species thatch. Hard fescue thatch adsorbed dicamba more rapidly and had a higher adsorption capacity than zoysia thatch, indicating that thatch age, pH and organic matter content play an important role in the sorption of ionic pesticides to thatch. Dicamba desorption losses from soil were greater than from zoysia thatch. This suggests that dicamba is more tightly bound than soil."
