USGA Summary Points:Previous transition zone research at the University of Arkansas on a relatively young (2-yr-old) Penn G2 sand-based green indicated that aggressive annual removal of 15-23% surface area via verticutting was required to keep mat layer organic matter below 4%. However, recovery of putting green uniformity took at least twice as long as coring. Our transition zone study in Richmond, Virginia is being conducted on 8-yr-old Penn A4 sand-based putting greens that are in-play, and began the trial at 5.8% organic matter (above the USGA recommended mat layer limit of 4%). Closely spaced core aeration, with or without verticutting treatments, were imposed spring and fall so that annual surface area removal of plots ranged from 10% to 27%. No overall bentgrass decline was noted during the 2008 growing season and none of the treatments affected soil temperature, soil moisture, or ball roll distance. Faster recovery was seen on those plots where surface area removal was the least. That is, where ¬ľ-inch tines were used at close spacing (1.33" x 1.5"), and the green was either cored once or twice.
