| Studies were conducted to determine the effect of undersoil heating on growth and quality of turfgrasses including Kentucky bluegrass (Poa pratensis L.¡®Nuglade¡¯), perennial ryegrass (Lolium perenne L.¡®Accent¡¯), tall fescue (Festuca arundinacea Schreb.¡®Pixie¡¯), and Korean lawngrass (Zoysia japonica Steud.) in simulated athletic field during winter season in Korea. Mineral contents in clippings of turfgrasses grown at different soil mixtures and temperatures were also analyzed. Undersoil heating (approximately 20$pm$2$^{circ}C$) was effective in protecting turfgrasses except Korean lawngrass from freezing injury and discoloration of shoots due to extremely cold temperatures during midwinter. Among turfgrasses grown at undersoil heating zone, tall fescue and perennial ryegrass showed the highest clipping weights and chlorophyll contents, respectively. However, anthocyanin contents of shoots were higher in Kentucky bluegrass. There was little or no difference in clipping weights, chlorophyll contents, anthocyanin contents and greenness of shoots between turfgrasses grown at two soil mixtures composed of 80% sand£«10% peat moss£«10% soil (v/v/v) and 80% sand£«20% pea moss (v/v). Contents of mineral K, Ca and Mg in clippings of cool-season turfgrasses were comparatively higher in a soil mixture composed of 80% sand£«10% peat moss£«10% soil, but little difference in contents of N and P was observed between two soil treatments. Results indicated that undersoil heating can improve quality of turf surface by thawing soil, melting snow, and maintaining shoot growth and greenness of turfgrasses in sports field during winter season. |
