| Abstract/Contents: | "The playing conditions of grass sportsfields strongly depend on the soil strength of the top layer. Apart from controlling soil water conditions, soil strength can be improved by increasing bulk density and the more so the higher the organic matter content. This will be at the expense of hydraulic conductivity. This paper describes the influence of differences in hydraulic conductivity and the soil water characteristic of 11 top layers and 3 subsoils, on the soil water conditions in the top layer. The investigation was carried out with an electronic analog simulating the non-steady vertical flow of water in soils as dependent on actual rainfall, physical properties of the soil and drainage conditions. From relationships between soil strength and pressure head established by field and laboratory measurements, pressure head limits for play could be derived for differently composed and variously compacted top layers. With the aid of these limits, the duration and frequency of unplayable situations could be derived from the simulated course of soil water conditions in the top layer. The results show the great significance of the subsoil with regard to soil water conditions in the top layer. The better the physical properties of the subsoil the less disadvantageous is a low conductivity of the top layer resulting from compaction and high organic matter contents. On subsoils with lower conductivities the rather poor sandy top layers function the best. To obtain sufficient soil strength, the pressure head in top layers with a low density must be considerably lower than in the case of more compacted top layers. However, the drier such a top layer has to be, the more frequent and the more prolonged will be the occasions when this lower pressure head is exceeded in wet periods." |
