| Abstract/Contents: | "Many golf courses in the arid southwestern states of the USA use irrigation water with high levels of bicarbonates. Perceived negative consequences of using such water are the accumulation of carbonates in the soil that can decrease soil porosity, infiltration rate, and in advanced stages, the formation of plugged horizons. Information is lacking on the impact of irrigation water high in bicarbonates on soil inorganic carbon dynamics and on turfgrass quality. A field study was conducted at New Mexico State University in Las Cruces to study whether a high bicarbonate concentration in irrigation water impedes infiltration due to accumulation of calcite in a native desert soil. The research area consisted of 2m by 2m Kentucky bluegrass (Poa Pratensis L.) plots, replicated three times and randomly arranged. Six unglazed ceramic bisque tiles (3-4 cm wide, 5 cm long) were randomly installed at a depth from 5 to 10 cm in each plot as an experimental matrix to determine a time-controlled accumulation of carbonates in plots irrigated with potable water (control, concentration of bicarbonates 160 ppm), with water high in bicarbonates (500ppm), and in non-irrigated soils under natural desert vegetation. Irrigation was applied daily at 80% of ETo One tile from each plot was removed monthly to determine carbonate accumulation using two methodologies. First, a quantitative estimation of calcite in a matrix material calculating concentrations of carbonates obtained analytically and expressed as a percentage of tile weight from acid dissolution followed by the volumetric analysis of the released carbon dioxide (CO2). Second, using Scanning Electron Microscopy and elemental composition control with Energy Dispersive X-ray analysis along the undisturbed surfaces of the tiles. Results of our investigation will be presented." |
