The internal soil nitrogen (N) cycle supplies N to plants and microorganisms but may induce pollution in the environment. Understanding variability of gross cycling rates resulting from global spatial heterogeneity climatic edaphic variables is essential for estimating potential risk loss. Here we compiled 4,032 observations 398 published
