Correlation matrix based on Pearson’s correlation coefficients among soil chemical properties in the study area.

		Correlations
				pH	EC (dSm^−1)	SOC (%)	Total N (%)	Av P (ppm)	Av K (ppm)	Av S (ppm)
pH	Pearson correlation	1
EC (dSm^−1)	Pearson correlation	−0.177	1
SOC (%)	Pearson correlation	0.342	−0.652	1
Total N (%)	Pearson correlation	−0.011	0.358	−0.209	1
Av P (ppm)	Pearson correlation	0.290	−0.174	0.501	0.041	1
Av K (ppm)	Pearson correlation	0.419	−0.173	0.558	0.001	0.413	1
Av S (ppm)	Pearson correlation	0.144	−0.235	0.094	−0.084	0.246	0.053	1

Correlation is significant at the 0.01 level (2-tailed). Correlation is significant at the 0.05 level (2-tailed).
