Abstract/Contents: | "For sports turf cost-effectiveness can be defined as the relationship between cost on the one hand, and carrying capacity and playing quality on thed other hand, carrying capacity being the amount of use the area will sustain without unacceptable deterioration. Without including quality in the relationship, analyses of cost-effectiveness are incomplete. Cost-effectiveness consists of two elements: cost and effectiveness. Although some costs given for local authority situations are reported here, the emphasis is on the "effectiveness" in terms of playing quality and performance of winter pitches. For football, the components of playing quality include traction, hardness, ball bounce resilience and rolling resistance. Other criteria by which we can judge turf performance include surface trueness, grass ground cover and species composition, and water infiltration rate. The response of turf to fertilizer is strongly influenced by (a) construction and drainage, and (b) intensity of use. Return or removal of clippings is also likely to be of importance. The response of turf to a wide range of nitrogen levels on a sand rootzone and on the local sandy loam topsoil, have been studied at Bingley. Before wear, measurements of turf performance generally show a large response to fertilizer. During wear, however, playing quality is largely dominated by the effects of rootzone construction. Nitrogen inputs of 200-300 kg/ha per annum are required to obtain maximum ground cover during wear on both sand and soil rootzones. However, the amount of grass cover remaining on the sand rootzone is always greater than on the soil. It is suggested that the priority should be to improve the construction and drainage of existing sportsfields. Unless this is done, expenditure on fertilizer and other aspects of maintenance of winter pitches could be viewed as `putting good money after bad'. Although the costs of improvement are large, so are the benefits in terms of carrying capacity and playing quality." |
