“…Sand topdressing is a less expensive and labor intensive alternative for lower value or larger turf areas. It also has the added benefit of diluting thatch accumulation and improving turfgrass health during the growing season (Gaussoin, Berndt, Dockrell, & Drijber, 2013).…”

Winter desiccation injury can severely impact golf courses in the northern and central Great Plains. While it is well-established that turfgrass crown moisture content (CMC) declines during fall cold-acclimation, little is known about CMC during winter desiccation stress and how management practices influence CMC during desiccation stress. The objectives of this study were to understand how protective covers, sand topdressing, and spray-applied treatments impact creeping bentgrass (Agrostis stolonifera) CMC and spring green-up following winter desiccation stress in Nebraska. Spray-applied treatments included a turf colorant, horticultural oil plus colorant, anti-transpirant, and a fall applied soil wetting agent. Crown moisture content was measured monthly from December to March at Mead, NE and after winter in Axtell, NE. Visual turfgrass quality ratings were used to monitor survival and spring regrowth. Late-fall sand topdressing and permeable and impermeable protective covers reduced winter desiccation injury compared to a non-treated plot. Turfgrass CMC ranged from 0.251 to 0.764 g H 2 O g −1 fresh weight (FW) depending on treatment and location. Logistic regression indicated that turf plants with a CMC of 0.518 g H 2 O g −1 FW had a 50% probability of significant winter desiccation injury. Under severe desiccation pressure, the spray-applied treatments did not prevent winter desiccation injury. Under these circumstances, a majority of plots receiving spray-applied treatments had a March CMC of less than 0.500 g H 2 O g −1 . Physical protection of turfgrass crowns with covers or sand topdressing in late fall sustained CMC during late-winter and decreased the potential for winter desiccation injury the following spring.Abbreviations: FW, fresh weight; CMC, crown moisture content.

“…Because of the deposition of clippings, along with senescing leaves, stems, and roots, an organic residue can form at the soil surface. This, in turn, can incite stem elongation and subsequent root growth within the layer of organic residue, forming a more stable layer immediately above the surface soil called thatch (Gaussoin et al, 2013). The subsequent inclusion of soil particles into the thatch—as a result of natural processes or cultural operations– produces a thatch‐like derivative, called mat (Ferguson, 1964).…”

Cultivation in managed turf systems, and in particular golf turf culture, refers to mechanical methods of selective tillage to modify physical and possibly other characteristics of turf. The earliest common cultivation practice was called “forking”, which used knives or a pitchfork. In the late 1940s and early 1950s, the first commercial production and distribution of cultivation equipment was the West Point Aerifer and the Verticutter. These early innovations not only were of value in helping turf managers manage soil compaction and thatch, they led the way to the development of a sophisticated array of equipment and practices that are employed today for improving and sustaining turf quality. Recently developed cultivation methods include water‐, sand‐, gravel‐, and air‐injection systems. Regardless of cultivation method or equipment, the goal is to achieve soil root‐zone and thatch modification with the least possible surface disruption.

“…O rganic matter accumulation in creeping bentgrass putting greens has been a concern since the innovation of sand‐based root zones (Gaussoin et al, 2013). Accumulation of OM can increase thatch in a putting green, creating a soft, saturated surface that results in decreased playability (Glasgow et al, 2005).…”

Soil cultivation is commonly used to manage organic matter (OM) accumulation in golf course putting greens. Our objectives were to determine: (i) if hollow‐tine cultivation is more effective than solid‐tine cultivation at managing OM and water infiltration, (ii) if venting methods are effective at managing OM and water infiltration, and (iii) if venting alters or interacts with effects of early‐ or late‐season cultivation. The study was a 3 × 5 factorial repeated on two ‘Providence’ creeping bentgrass (Agrostis stolonifera L.) research putting greens. Tine treatments were hollow‐tine, solid‐tine, or no‐tine cultivation. Venting treatments were Hydroject, PlanetAir, quad needle tine, bayonet tine, or no venting. Soil samples were collected and analyzed for OM content using loss on ignition. Water infiltration rates were determined in situ. After 2 years, there were few consistent differences found among the tine and venting treatments, and there were no significant interactions regarding OM concentration. This response was attributed to the small amount of surface area impacted by cultivation and to the equalization of topdressing quantity across all treatment combinations. Hollow‐tine and solid‐tine cultivation increased infiltration compared with no cultivation. In general, Hydroject treatments increased water infiltration rates more than all other venting treatments regardless of tine treatment.
