Abstract/Contents:"Sixty-minute, constant-intensity simulated rains were applied to seven infiltration treatments designed to evaluated the influence of stripping and compaction on home lawns. Three treatments simulated home lawn construction practices. The control treatment was undisturbed, the "stripped" treatment had the topsoil removed and replaced. All plots the "compacted" treatment had the topsoil removed, the exposed surface compacted and the topsoil replaced. All plots were rototilled and raked before sodding to establish the grass. In addition, stripped and compacted treatments were identified and tested on a 6- and a 12-year-old lawn. All treatments were replicated six times. The K and Lambda = nPsi + na parameters in the Green and Ampt infiltration model were filled to the cumulative infiltration data for each replication of each of the seven treatments. The time, tr, when runoff began was recorded for each replication. The treatments generally divided into three groups. The most rapid infiltration occurred on the newly constructed control and stripped treatments (K = 85 mm/h), though the shape of the infiltration response and the time to the start of runoff were quite different. The slowest infiltration occurred on the newly constructed and the 12-year-old compacted treatments (K = 33 mm/h). The reduction in infiltration into the compacted layer could still be seen 12 years after the compacted layer was developed even though there was a trend toward faster infiltration with age. An intermediate infiltration response occurred on both the 6-year-old stripped and compacted lawn and the stripped portion of the 12-year-old lawn (K = 54 mm/h). The reduced infiltration into the compacted layer in the 6-year-old lawn was attenuated by repeated aerations."
