“…Increased soil P availability and changes in foliar P properties in urban and suburban forests are likely a result of increased P inputs from animal droppings, vehicles, dustfall, precipitation (Pett-Ridge 2009) and various anthropogenic waste deposits (Zhang et al 2001;Chen et al 2010b), although they have not yet been quantified in our study area. However, this P enhancement is also likely due to increased decomposition of organic matter and accelerated weathering induced by elevated N deposition, CO 2 , O 3 and temperature as separate process or in combination (Isebrands et al 2001;de Groot et al 2003;Campbell and Sage 2006;Ghannoum et al 2010).…”

“…High P accumulation in urban and suburban soil is a potential non-point pollution source for surface and ground waters (Zhang et al 2001). Scientists have been interested in quantitatively assessing high soil P storage as an indicator of the potential for P leaching (Hesketh and Brookes 2000).…”

“…However, soil P can also be a pollution source and a threat to water quality when P availability increases so substantially that P is transported to water bodies by surface runoff and groundwater infiltration (Heckrath et al 1995;Zhang et al 2001Zhang et al , 2005. Because soil P turns over slowly, the legacy of enhanced soil P patterns may affect freshwaters for centuries (Bennett et al 2004).…”

“…Because soil P turns over slowly, the legacy of enhanced soil P patterns may affect freshwaters for centuries (Bennett et al 2004). Soil total P levels as well as varied fractions have been reported to be elevated in urban regions compared to suburban and rural regions (Zhang et al 2001;Zhang 2004;Yuan et al 2007). The accumulated P has become a potential non-point source of pollution for surface and ground water in some cities (Zhang et al 2001(Zhang et al , 2005.…”

“…In urban forests, soil P can be imported with animal droppings, vehicles, dustfall, precipitation and various anthropogenic waste deposits (Waller 1977;Zhang et al 2001). Therefore, soil P transformation and plant P uptake (P cycling) may be altered with urbanization.…”

Urbanization has been rapid across the world but the responses of phosphorus (P) cycling to urbanization have not been well-investigated. This study was to understand the influences of rapid urbanization on forest P cycling in a developing country. Soil P fractions and P resportion were determined for nine slash pine (Pinus elliottii Engelm.) forests along a 30-km long urban-suburban-rural gradient in Nanchang City, southern China. The total P stocks in the surface soils in urban and suburban forests were 317% and 182% higher, respectively, than levels found in rural forests. The concentrations of soil available P, labile P, slow P, occluded P and total extractable P were also much higher in urban and suburban forests than in rural forests (P<0.05). Soil weathered P concentrations were highest in urban forests. Annual mean foliar P concentrations were enhanced in urban and suburban forests compared to rural forests. The P resorption efficiency (PRE) was higher in rural forests than in suburban and urban forests, while the P resorption proficiency (PRP) was lower in rural forests than in suburban and urban forests. Urbanization associated with high extraneous P inputs has altered soil P status and plant P uptake. Foliar P concentration, PRE and PRP were largely dependent on soil P availability in our study forests.

Human activities can affect the biogeochemical cycling of phosphorus substantially. However, the relationship between P accumulation and urban development process is largely unknown. This study investigated the influence of urban development on the P accumulation in urban and suburban soils, using Nanjing (China) as a case. Based on its urban development history, Nanjing was divided into suburban and urban area, and the urban area was subdivided into urban north and urban south. Soil total P (TP) and available P (AP) of 578 samples from 68 pedons at different locations were measured. Thickness‐weighted mean P content of each pedon (Pw), P content of the surface soil layer (Ps), the highest P content of each pedon (Ph), and the lowest P content (Pl) of each pedon were selected as statistical indices. Compared with the background value, urban and suburban soils were enriched in P. The highest TP content was up to 11.14 g P kg–1, and the highest AP content was up to 360 mg P kg–1. However, analysis of variance (ANOVA) and multiple comparisons of Pw, Ps, Ph, Pl showed that urban south with longest residential history had the highest TPw, TPs TPh, and APw, APl contents, and urbanizing suburban had the lowest TPw and APw, APl contents. For both APs and APh, there was no significant difference between suburban and urban area. However, significant differences between urban south and urban north were observed. The results demonstrated that urban development process, including population quantity and level of urban infrastructure, could influence soil P accumulation and distribution in urban environment. A more detailed assessment is required to avoid the potential secondary eutrophication caused by excess P release from those anthropogenic high‐P soils.
