| Abstract/Contents: | Discusses factors that may be associated with the deterioration of slit drainage systems in the sand carpet layer of athletic systems, highlighting "insufficient control of the rate of organic matter accumulation in the surface sand layer protecting the integrity of the slit trains, and failure (or inability because of legislation or policy) to control the level of earthworm activity in the soil underlying the sand layer." Mentions the development of an auditing system "based on a rating scale that graded each drainage component of a slit drained system (sand carpet layer, slit drain system and lateral drain system) depending on its visual conditon. Results were presented in such a way that an informed judgement could then be made of the estimated remaining economic life of a particular sports field and so that funds could also be budgeted for future repair and maintenance." Reports that "this initial work showed that the rate of limiting drainage component for the majority of sports fields assessed was, not suprisinlgy, their sand carpet layer - fields that performed poorly did so, in the majority of cases, because the sand carpet layer had become contaminated and not because lateral and slit drains had ceased to function." Mentions potential benefits of sand topdressing and scarifying to sand carpet sports fields, stating that "regular sand topdressings have been the main control mechanism for managing sand carpet contamination." Compares the cost of scarifying and sand topdressing to complete surface removal. Concludes that "the measurement of contamination by fines in a sand carpet rootzone by a simple water settlement test offers a useful application for on-going quality monitoring purposes"; "the presence of earthworms more than doubles the cost of managing surface contamination"; "the ability to control earthworm activity is a fundamental requirement for reducing maintenance costs"; "for ryegrass sports fields, complete turf removal for control of contamination would become cost-effective as an alternative to preventative scarifying only if it was required on a frequency of less than once every four years for earthworm-active fields, or less than once every nine years for earthworm-free fields"; and "for couchgrass sports fields, complete turf removal for control of contamination would become cost effective only if it was required out on a frequency of less than once every five to six years for earthworm-active fields, or less than once every twelve years for earthworm-free fields." |
