摘要

Golf course putting greens are intensively maintained and often contain a sand based root zone and, therefore, need to be managed to prevent nitrate and pesticide contamination and ground and surface water pollution. In this laboratory study, the water and solute movement through a typical tri-layer US Golf Association putting green profile was investigated. Results indicate that even though the soil layers were homogeneous, preferential flow paths were formed, causing a major portion of the soil profile to be bypassed and, thus, increasing the likelihood of groundwater contamination.
