Moran’s I correlograms for soil MBC concentration under three N fertilization treatments (i.e. NN, LN and HN) in SG and GG cropland soils in a three-year long fertilization experimental site at the Tennessee State University (TSU) Agricultural Research Center in Nashville, TN, USA. Filled circles denote Moran’s I values that exhibited significant positive or negative autocorrelation. Obs: observations; LCL: low confident limit; and UCL: Upper confidence limit. Other abbreviations are referred to Table 1.
