Abstract/Contents:"Organic matter accumulation and carbon sequestration are ecosystem services provided by urban landscapes that are dominated by continuous grass cover, such as residential lawns. These parameters are expected to increase over time, but few studies have determined potential accumulation from residential lawns in semiarid climates. The objectives were to evaluate physicochemical attributes of urban soils established under turfgrass landscapes of different ages and determine soil factors that segregate urban soils in a semiarid climate. Soil samples were obtained from 10 locations within each home age category: oldest (pre-1970), middle (1971-1990), newer (1991-2010), and newest (2011-present). Soil texture, bulk density, extractable nutrients, pH, soil organic matter (SOM), soil organic carbon (SOC), and total nitrogen (TN) were determined to a 10 cm depth. Bulk density and pH were highest in newest homes and lowest in oldest homes, but no differences in CEC, K, Mg, or Ca were identified. Increasing home age increased SOM, SOC, and TN regardless of management practices as determined by homeowner surveys and variation of visual quality of turfgrass within home age categories. This result suggests management practices may not affect accumulation rates. In principal component analysis, SOM, SOC, and TN contributed most to PC1 (36.2%), with primarily soil texture components for PC2 (22.5%). These findings support previous research that limiting C-intensive management practices would not alter SOM or SOC accumulation in a semiarid environment, but would reduce the C footprint of the urban landscape."
