Abstract/Contents:"Sand-based athletic fields and golf course greens often contain large amounts of calcium carbonate. Calcium (Ca) is frequently applied to these areas based on the belief that the Ca within the calcium carbonate is not readily available for plant use. Our objectives were to determine if applications of additional Ca to grass grown on a calcareous media increase Ca uptake, and affect the clipping yield or quality of the grass plant. In 1999, a two-year field trial was established on a sand-based `Crenshaw' creeping bentgrass green. Treatments, including a control, gypsum, calcium carbonate, calcium nitate, and liquid calcium chelate, were applied over 5 months at 4.5 g Ca m-2 per month. Urea was added to balance the N found in the calcium nitrate and calcium chelate treatments. During the first year, there were no differencesin tissue Ca content, visual quality or clipping yield in response to the Ca treatments. The control had an average Ca concentration of 5.4 g kg-1, and the calcium sulfate, calcium carbonate, calcium nitrate, and calcium chelate had average Ca concentrations of 5.6, 5.6, 5.6, and 5.8 g kg-1, respectively. Application of Ca did not affect the concentrations of any other nutrient."
