| Abstract/Contents: | "Athletic fields and golf course greens are often constructed of calcareous sands. Supplemental calcium (Ca) applications are frequently recommended to these areas based on the belief that the Ca from the CaCO3 in the medium has limited availability to the plant. Our objectives were to determine if applications of additional Ca to grass grown on both calcareous and silica medium increase the amount of Ca absorbed by the plant and if Ca applications increase the clipping yield and quality of the grass plant. 'Midnight' Kentucky bluegrass (Poa pratensis L.) and 'Penncross' creeping bentgrass (Agrostis palustris Huds.) were grown on either calcareous or silica sand during two greenhouse experiments. Treatments included a control, calcium sulfate (CaSO4), calcium carbonate (CaCO3), calcium nitrate [Ca(NO30)2·4H2O], and calcium chelate incorporated into the media at 23 g·m-2 Ca. The Ca treatments did not affect the clipping weights of Kentucky bluegrass grown on calcareous sandin either experiment. Of the five Ca treatments applied to creeping bentgrass grown on calcareous sand in the first study, only CaCO3 increased total clipping weight. This effect was not repeated in the second study. There were no differences in Ca tissue content in response to Ca treatment for either species grown on calcareous sand. With the exception of the CaSO4 treatment in the second study, adding Ca to silica sand increased the concentration of Ca of creeping bentgrass an average of 78% in study 1 and 60% in study 2. In the first study, adding CaCO3 or Ca chelate to Kentucky bluegrass grown on silica sand also increased the leaf Ca content by 48%. But these increased concentrations of Ca on silica sand were not different from the amount of Ca found in grass grown on the calcareous control. Kentucky bluegrass and creeping bentgrass are capable of obtaining Ca from calcareous sands, and no additional Ca is needed." |
