Pearson correlation coefficients matrix of soil pH, electric conductivity (EC), bulk density (BD), organic matter (OM), soil porosity (SP), soil sand particle size composition (SS), soil silt particle size composition (SSI), soil clay particle size composition (SC), soil water content (SW), total nitrogen (TN), > 0.25 mm soil aggregate content (SA > 0.25). The correlation coefficients were listed in the upper right matrix and the significance were presented in the lower left of matrix. The red color indicates positive correlation, and the blue color indicates negative correlation. The * and ** designates the coefficient is significant at the 0.05 and 0.01 level of probability, respectively.
