Abstract
Field studies were conducted at two locations in Pullman, WA, over two growing seasons (2008 and 2009) to determine the effects of cultivation method, cultivation timing, and topdressing sand color on thatch-mat management, golf green surface injury, and golf green surface quality of a 'T-1' creeping bentgrass (Agrostis stolonifera L.) golf green. The field study at the Palouse Ridge Golf Club evaluated six cultivation methods and two topdressing materials for their ability to manage thatch-mat accumulation and minimize injury to the golf green. Cultivation treatments included core removal, venting, vertical mowing, and combination treatments in conjunction with black sand (BS) topdressing and tan sand (TS) topdressing and an untreated control (UTC). Within a cultivation method, BS resulted in fewer days injured when compared to TS. Black sand also improved turfgrass quality and color over TS. Cultivation methods with more severe injury resulted in a greater decrease in turfgrass quality. Vertical mowing resulted in the greatest thatch-mat layer, while the UTC had the least; however, the thatch-mat organic matter content was inversely related to thatch-mat depth with the UTC being greatest and vertical mowing being least. Cultivation method had no impact on ball roll distance (BRD), but BRD measured before cultivation was greater than after cultivation. The field study at the WSU Turfgrass and Agronomy Research Center investigated the effects on the number of days to recovery after aeration and on turfgrass quality and color of core aeration applied at 9 or 11(2008 or 2009) dates using two types of topdressing sand. In the spring, mid-May aeration resulted in the fewest days to recovery. In the fall, mid-August to mid-September aeration was quickest to recover. Black sand resulted in fewer days to recover than TS in the fall. Additionally, BS improved turfgrass quality and color, especially in the spring and fall. Black sand also increased soil temperature within an aeration date over TS. Selecting the appropriate cultivation method and timing with BS topdressing in spring and fall can minimize injury while managing thatch-mat and maintaining acceptable golf green quality.
