Abstract/Contents:1983 update of 30 month test on ecological side-effects of high maintenance (regular schedule of fertilizer, herbicide, and insecticide application) of lawn turf (Kentucky bluegrass). Leaf-feeding, Soil inhabiting, and predatory invertebrates are sampled throughout the year and their numbers compared to those in untreated check plots. Predatory arthropods (spiders, ground beetles, rove beetles) were significantly reduced by insecticide applications, but their populations were only temporarily suppressed. Soil-inhabiting mites (may play a role in thatch degradation) were not affected by the treatments. Probably the most important change in soil fauna was in earthworms, which were significantly reduced after 2-years on the maintenance schedule. Soil acidification was beginning to occur in the treated plots, which may have adversely affected the earthworms. The experiment will be continued in 1984.
