The introduction of the microbiological properties increased the sensitivity of the index compared with SSQI B, which considered only the biochemical properties.
Correlation coefficients of SQls with varimax-rotated scores of PC 1 obtained from all significant data were 0.94 for SSQI A and CSQI A, 0.92 and 0.93 for SSQI B and CSQI B respectively, 0.88 for MSQI 1, and 0.76 for MSQI 2.
Only the SQIs that included a physical indicator (MWD 1) were sensitive to differentiation by time under production (SSQI B and CSQ1 B).
The SSQ1 A was more efficient in separating by management system, whereas SSQI B was able to differentiate according to number of years under production.

The CSQI A was integrated by the same indicators as SSQI A.
Correlation coefficients of soil quality indices with varimax rotated scores of PC 1 obtained from all significant data were 0.97 (for SSQI A and CSQI A), 0.98 (for SSQI B, CSQI B, and MSQI 1), and 0.99 (for MSQI 2).
