Abstract/Contents:"Interpretations of soil zinc (Zn) tests for golf course greens vary among testing laboratories, with little information in the literature on which to base these interpretations. Our studies determined the effects of increasing fertilizer Zn on extractable soil Zn and tissue Zn levels for five creeping bentgrass (Agrostis palustris Huds.) cultivars, to investigate their potential for Zn toxicity. The effects of Zn concentrations up to 4000 mg/kg were investigated in three greenhouse studies on a potted soil mix of sand. Nicolett (fine-loamy, mixed mesic, Aquic Hapludoll) soil, and Hypnum peat in an 8:1:1 ratio. 'Penncross' bentgrass was used in the first two studies, and 'Penncross', 'Penneagle', 'Cobra', 'Emerald', and 'Prominent' were compared in a third study. Mean DTPA-extractable soil Zn concentrations increased from 0.6 mg/kg in the controls to 652 mg/kg in the pots treated with 4000-mg Zn/kg soil. Tissue Zn concentrations increased from a low of 50 mg/kg for grass on the control pots to a high of 1500 mg/kg for plants grown in soil treated with 4000 mg/kg soil. No consistent deleterious effects were observed on the grass tissue of any of the varieties. Our study demonstrates that creeping bentgrass is capable of tolerating very high levels of Zn without tissue damage."
