The patterns of soil nitrogen stocks and C : N stoichiometry under impervious surfaces in China

Qian Ding, Hua Shao, Chi Zhang, and Xia Fang

Data sets

Observations of soil nitrogen and soil organic carbon to soil nitrogen stoichiometry under the impervious surfaces areas (ISA) of China Qian Ding, Hua Shao, Chi Zhang, and Xia Fang https://doi.org/10.12072/ncdc.socn.db2851.2023

Short summary

A soil survey in 41 Chinese cities showed the soil nitrogen (N) in impervious surface areas (ISA; N_ISA) was 0.59±0.35 kg m⁻², lower than in pervious soils. Eastern China had the highest N_ISA but the lowest natural soil N in China. Soil N decreased linearly with depth in ISA but nonlinearly in natural ecosystems. Temperature was negatively correlated with C : N_ISA but positively correlated with natural soil C : N. The unique N_ISA patterns imply intensive disturbance in N cycle by soil sealing.
