| Abstract/Contents: | "Soil water repellency (SWR), or soil hydrophobicity, is often a serious hindrance to the quality and uniformity of turfgrass managed in sand-based root zones. This phenomenon has been reported in 'constructed' and natural turfgrass systems worldwide. Requisite edaphic components for SWR development include: particulate organic matter, microbial activity, cycles of wetting and drying, and limited specific surface area in the mineral fraction. Ostensibly, SWR threatens to be a continuing problem in intensively trafficked and managed turfgrass systems. For this reason, turfgrass managers are interested in the temporal scale of SWR development, and any use-related processes that may hasten or delay its progression. Our objectives were to determine: (i) temporal dynamics of SWR in a 80:20 (v:v) USGA sand/sphagnum peat root zone established with creeping bentgrass [Agrostis stolonifera L. var. palustris (Huds.) Farw. 'Crenshaw']; and (ii) how SWR formation rate interacts with repeated compressive forces applied to the surface of these root zones (simulated traffic). A greenhouse study was conducted over 18 months, in which root zones were destructively analyzed to assess SWR and physical stability. Results showed time (maturity) to correlate highly with SWR development in the upper 3 cm of root zones. Subcritical SWR was detected six months after establishment. Compaction did not consistently increase SWR over the entire experimental period, but did increase SWR severity in the first six months. Results show SWR can develop in the upper 3 cm of sands within six months of establishment, and its severity will likely increase over the following year." |
