| Abstract/Contents: | "There is a widely held belief in the turfgrass industry that bicarbonate from irrigation water can accumulate and cause physical problems in the soil despite a lack of evidence for this claim. The objective of this study was to quantify accumulation of carbonate (soil inorganic C [SIC]) from irrigation water in a simulated root zone of a sand putting green fertilized with two different N sources (ammonium sulfate or potassium nitrate). To track SIC additions from irrigation water, sand columns were irrigated with low salinity, carbonate-enriched water containing 13C-labeled bicarbonate and compared with a control irrigated with deionized water. After 20 mo, which was equivalent to about 3.5 yr of typical irrigation on a golf course, soil pH, SIC, and δ13C were measured by depth. Acidity from nitrification of ammonium sulfate applications offset alkalinity inputs from carbonate-enriched irrigation water and resulted in net acidification of soils, especially from 0 to 5 cm in depth. Soil inorganic C accumulation was observed in columns irrigated with carbonate-enriched water but did not result in decreased air permeability of the root zone. There were no significant differences in soil δ13C among experimental treatments despite δ13C differences in turf leaf tissue. This suggests that SIC applied through irrigation may accumulate in the soil, but is subject to isotopic exchange with atmospheric CO2 (gas). These findings do not support the claim that irrigating turfgrass with water containing elevated levels of bicarbonate will negatively impact soil physical properties." |
