Abstract/Contents:Profiles the organic matter dilutions programs for sand-based putting greens, their objective is to "compare various cultivation approaches that remove from 10 to 27% surface area and determine treatments effects on agronomic performance of a mature putting green in east-central Virginia." Explains that "aggressive organic matter dilution programs are intended to slow loss of aeration porosity and subsequent infiltration rates thereby allowing superintendents to more easily manage their putting greens."

USGA Summary Points:The least disruptive treatment in terms of percent removal (Trt 2, 10%) healed quickly (24 to 34 days) and reduced thatchmat OM to an acceptable level of 3.4% after two years. Verticutting alone each spring and fall (Trt 3) resulted in the second fastest recovery of any treatment (21 to 24 days), but failed to significantly reduce OM to a level below the untreated. Treatment 4 resulted in the least amound of days of disruption over the season (38), while also reducing OM to an acceptable 3.7%. Total recovery time was 7 days less than verticutting-alone, with a slightly faster rate of OM reduction. Using large tines (0.5" ID) at a close spacing both spring and fall each year (19.6% surface removal, Trt 6) worked best in terms of final OM at 3.0%, but required approximately two extra weeks each season for recovery relative to two passes with small tines or verticutting alone. Being ultra-aggressive by removing 26.6% surface area (Trt 7) per year did not work in this trial. Recovery time was significantly delayed without achieving greater OM dilution relative to treaments that removed 10 to 20% surface area.
