Abstract/Contents: | Discusses thatch management, explaining that "thatch is the intermingled layer of undecomposed organic material between the turf canopy and soil surface." States that "thatch and mat play an important role in cushioning the turf surface, improving wear tolerance, decreasing soil compaction and protecting the crown of the plant." Lists issues that can be caused by thatch accumulation, including "increased pest damage"; "decreased water and nutrient retention"; "reduced water infiltration"; "increased potential for localized dry spots"; "decreased root health"; "reduced tolerance to extreme temperatures"; "reduced efficacy of certain pesticides"; and "higher potential for scalping and crown damage." Suggests using smaller amounts of nitrogen and watering turf deeply and infrequently as potential techniques for reducing thatch accumulation." Concludes that "the important thing to remember about thatch levels is that they need to be monitored each season, since there are so many factors that can affect accumulation, including the weather itself. There is no doubt that excess thatch is detrimental to turfgrass growth, regardless of what part of the golf course is affected. Although many thatch reduction maintenance practices are disruptive, a couple of weeks of less-than-ideal playing conditions is well worth it in the long run. Turf will be healthier and more stress tolerant." |
