| Abstract/Contents: | "Fraise mowers are aggressive tractor-mounted implements that can remove plant and soil material from 0 to 5 cm (0 to 2 in.) depths. Compaction from routine traffic in turfgrass systems is usually confined to the surface 7.6 cm (3 in.) of the soil profile, which overlaps with fraise mower functional depths. This study was conducted to evaluate fraise mowing as a viable cultivation method to remove surface compaction beneath hybrid bermudagrass. A trial was conducted in 2018 on a sandy soil in Jackson Springs, North Carolina. Plots were subjected to 0, 20, or 30 passes with a modified Baldree traffic simulator, all plots were then fraise mowed at 2.5 or 5 cm depths, and measurements were made following traffic simulation and fraise mowing. Soil hardness increased with the number of games simulated. All traffic levels had similar soil hardness values after fraise mowing. Trafficked treatments (20 and 30 passes) had lower soil hardness values after fraise mowing, and non-trafficked control treatments had a 29% increase in soil hardness after fraise mowing. However, volumetric water content was 43% less at sampling after fraise mowing, which may have increased non-trafficked control soil hardness values. Saturated hydraulic conductivity (Ksat) decreased 32% after fraise mowing at the 2.5 cm depth and remained static at the 5 cm depth (5.6 cm hr-1) after fraise mowing. Lower soil hardness values following fraise mowing in trafficked plots indicates the potential for compaction relief. However, lower Ksat rates at 2.5 fraise mowing depth may indicate potential soil crusting. This study will be repeated in 2018." |
