Abstract/Contents:"In many intensively cultured turfs, thatch is recognised as a potentially serious problem. For decades, topdressing and an array of other cultural treatments have been used in attempts to control thatch. Several researchers have documented the effects of topdressing on thatch control; in most studies, results were expressed as the percent organic matter (OM) of the thatch or thatch-like derivative. The objective of this study was to evaluate the effects of different topdressing treatments on thatch biodegradation. A 10-yr-old experiment conducted on a Penncross creeping bent (Agrostis stolonifera L.) green at the Hancock Turfgrass Research Center at Michigan State University involving seven topdressing treatments was used for this study. Samples measuring 5 x 3 x 5 cm(LxWxD) were extracted from the green and separated into four 1.25 cm layers for OM content analyses. Total OM was determined by ashing and expressed as g cm⁻³. The results of this study suggest that dilution of the thatch with topdressing soil is at least as important as accelerated biodegradation in controlling the problems associated with excessive thatch accumulation. It was also shown that the frequency of topdressing for a given soil mix did not influence the amount of OM found."
