Table 4 Summary of significant distance for spatial dependence based on Moran’s I values for MBC, MBN and MBC:MBN in 12 plots in a three-year long fertilization experimental site at the Tennessee State University (TSU) Agricultural Research Center in Nashville, TN, USA. The unit of the distance for spatial dependence is meter. The abbreviations are referred to Table 1.
