Heating turf by underground warm air

  1. G.G. Fisher

Abstract

Underground forced air has been developed as a means of improved soil warming. Perforated plastic pipes are placed at subsoil depth in a permeable soil profile, and regulated amounts of moist warm air are released to give uniform heating at the surface. Intermittent heating at levels up to 300 W/m2 produced a 10 C temperature rise in 48 hours. No damage to turf was noted following heat inputs up to 500 W/m2. Based on 3-year results, a system has been designed for rapid and, if necessary, prolonged heating of football fields combined with improved turf growth and surface drainage. Additional index words: Football fields, Plastic pipes.
