| Abstract/Contents: | Presents a field study conducted to investigate "the potential changes in physical properties of sand-based root zones over a seven year period." Details methods and materials used in the study, stating that "intact core samples (76 mm [millimeters] diam. [diameter]) of the root zone were removed from the 0- to 76-mm depth of each plot in 1999 and 2005...Bulk density, porosity and saturated hydraulic conductivity (Ksat) were measured for each core sample." Reports that "bulk density of the 0- to 76-mm depth of the root zone indicated some compaction occured from 1999 to 2005, with greater bulk density observed for root zones in the enclosed location. As expected, air-filled porosity (at -3 kPa [kilopascal]) was the portion of total pore space that decreased the most over time." Also reports that "turf quality was generally better on amended root zones compared to straight sand plots in 2005. Root zone treatment effects on turf quality were typically consistent across microenvironments except in June and August." States that "accumulation of OM [organic matter] above the surface of [the] amended-sand root zones (that is, development of the mat layer) had greater influence on water retention and flow than the underlying root zone mixtures." Concludes that "observed changes in the physical performance and quality of putting greens over time will most likely be due to mat layer development and management rather than deleterious changes in the root zone profile." |
