MONITORING SEASONAL SOIL WATER REPELLENCY IN USA GOLF COURSE PUTTING GREENS

摘要：

　　Soil water repellency (SWR) is a common problem on golf course putting greens,fairways and tees,and contributes to a reduction in turfgrass quality,uniformity and playability.Although many field studies have investigated the causes and management of SWR in turfgrass rootzones,the relationship between turfgrass growth patterns and SWR has not been examined.The water drop penetration test (WDPT) was conducted to determine the existence and severity of SWR.Research reports have been reviewed containing WDPT data from one cool-season turfgrass location and one warm-season turfgrass location in the USA.In review of the data from three years of field trials at each location,an overall trend indicates SWR is greater in warm-season turfgrass and coolseason turfgrass sites in the summer and fall,respectively.Understanding factors that contribute to SWR may lead to the improvement of cultural and chemical practices as well as plant and soil health programs designed to alleviate SWR in turfgrass rootzones.
