The objectives of this study were to determine the response of greenhouse-grown creeping bentgrass (Agrostis palustris Huds 'Penncross') to Cu treatments in rooting media that ranged from 0 to 600 mg·kg⁻¹, and to provide an estimate of potentially toxic plant-available Cu by use of the DTPA-TEA soil test. Calcareous and silica sands were mixed individually with dakota peat moss in a 9:1 (v/v) ratio. 'Penncross' sod plugs were placed on the top of pots containing the premixed sand-peat media, and allowed to grow for 12 weeks. The average dry weight of clippings for plants grown in silica sand decreased 16% as Cu treatments increased from control to 600 mg·kg⁻¹. At the 600 mg Cu·kg⁻¹ treatments, dry root mass was 56% and 48% lower than the control treatments for plants grown in silica and calcareous sand, respectively. The DTPA-TEA soil test extracted on average 19% more Cu over all treatments from the calcareous as compared to the silica sand medium; yet, plant roots contained an average 34% more when grown in silica sand. These results indicated that the DTPA-TEA soil test was not a good predictor of potentially toxic plant-available Cu in sand-based media and alternative soil tests should be investigated."
