Abstract/Contents:"Prevention of frost, snow and surface mud is an increasing requirement on turf used for winter sport. Soil warming by conduction from electrical wires or hot water pipes is slow and uneven, and may restrict the growth and maintenance of turf. Underground blown air was investigated as a means of improved soil warming. Beneath specified topsoil mix, freely permeable to air and water, perforated plastic pipes were placed at subsoil depth and fed with moist warm air under pressure. To counteract the fall of temperature along the pipes, a variable perforation pattern was employed, thus regulating the release of air to the soil to give uniform heating at the surface . Intermittent heating at levels up to 300 watts/m2 maintained even temperatures at the turf surface 10°C higher than unheated surrounds. No damage to turf was noted at heat inputs up to 500 watts/m2. Compared with controls, warmed turf has shown increased root growth, and starts growth up to six weeks earlier in the spring. Based on three years results, a system has been designed for rapid and if necessary prolonged heating of football pitches which meets all requirements for turf growth and surface drainage. It provides for intensified use of natural turf without recourse to plastic substitutes."
