Soil log showing the main pedological horizons (i.e. A, Er, Brt, Bcr and Cr—A = surface (topsoil) horizon; E = eluvium soil horizon (horizon leached of its mineral and/or organic content, B = subsoil horizon (layers which are significantly altered by pedogenesis, mostly with the formation of iron oxides and clay mineral); C = parent material horizon (layer marginally affected by pedogenesis). When indicated, abbreviations for master soil horizon subdivisions are: r = weathered or soft; t = accumulation of silicate clays; c = concretions or hard nodules), semi-quantitative colony forming unit (CFU) counts of B. pseudomallei (CFU g−1), and soil physical parameters along the 300-cm deep profile: texture (i.e. percentages of silt, sand and clay), porosity (Poro), bulk density (BD), volumetric water content (WC), groundwater persistence rate (GPR) and saturated hydraulic conductivity (Ks).
