USGA Summary Points:There was generally very little casting activity in the light topdressing soil rootzone treatment throughout the two years of this study and casting activity was significantly greater under heavy topdressing in the soil rootzone (Fig. 1). In the sand rootzone, there was no significant difference in casting activity between topdressing treatments in year one; however, in year two, light topdressing resulted in significantly greater casting activity compared to the heavy topdressing treatment (Fig. 1). In addition, casting activity in the sand rootzone treatments was similar to casting observed in the soil rootzone with heavy topdressing (Fig. 1). Soil temperature varied over time between treatments (Fig. 2). The relationship between soil temperature and casting activity was significant and soil temperature explained 10-34% of the variation in casting activity within a rootzone/topdressing treatment combination (Fig. 3). Within both rootzones, the light topdressing treatment resulted in significantly greater soil moisture content across the two years of the study (Fig. 4). The relationship between soil moisture content and earthworm casting activity was not significant. Morphological identification indicated that the Lew Wentz adult specimens were comprised of Aporrectodea and Amynthas spp. Jimmie Austin Golf Course contained Amynthas spp. as well as some unidentified adult and juvenile specimens. Molecular identification indicated that specimens collected from the University of Arkansas, Meadowbrook Country Club, and Chenal Country Club grouped with the North-American native Diplocardia genus. Several individuals from UA and Meadowbrook grouped with Amynthas and Metaphire spp.
