Partial Least Squares Regression (PLS-R) analysis where the natural logarithm of the semi-quantitative colony forming unit (CFU) counts of B. pseudomallei (logCFU) are compared with soil physico-chemical variables: (a) logCFU in the correlation circle with the 24 soil parameters; (b) Measured and predicted logCFU using the PLS-R model; (c) Variable importance for the projection (VIP) score plot of the 24 soil physico-chemical variables. Fe total iron concentration, Al total aluminum concentration, Mn total manganese concentration, S total sulfur concentration, Ti total titanium concentration, K total potassium concentration, Si total silicium concentration; pH, OM organic matter content, Mg_e exchangeable magnesium fraction, Ca_e exchangeable calcium fraction, Na_e exchangeable sodium fraction, K_e exchangeable potassium; silt, sand and clay textural fractions; Poro soil porosity, BD bulk density, WC volumetric water content, GPR groundwater persistence rate, Ks saturated hydraulic conductivity.
