Two weeks after removing 5% of the surface area with one core aeration. Decreasing the amount of surface area removed during core aeration limits improvements in bulk density, surface water infltration and surface hardness, while decreasing healing time. RESEARCH SAYS • The combination of the percent of surface area removed per year and the number of core aerations per year affects turf quality, bulk density, surface hardness, thatch depth, soil organic matter content and surface infiltration rate. 2. 3. 4. 5. • Increasing the surface area removed per year decreased turf quality and bulk density. 6. • As the number of core aerations was increased, bulk density decreased and the playing surface became softer. 7. 148 GOLF COURSE MANAGEMENT 01.14 Illinois, Urbana, Ill.
