This dataset has been collected thanks to the long-term partnership with Department of Agricultural Land Management (DALaM), Lao PDR, which granted the permission for field access, and to the financial, scientific, technical, and/or logistical support of the Multiscale TROPIcal CatchmentS (SNO M-TROPICS; https://mtropics.obs-mip.fr/) critical zone observatory (previously MSEC). This .csv dataset includes Burkholderia pseudomallei concentrations (CFU g-1) within a 300-cm soil profile, along with physico-chemical parameters: soil texture, i.e. clay < 2 μm, silt 2–50 μm, sand 50–2000 μm (%); pH (-); organic matter content (%); bulk density (1000 kg m-3); total porosity (100(1-BD/2.65)) considering a real density value of 2.65 (%); groundwater persistence rate (%); saturated hydraulic conductivity (mm h-1); soil water content (m3 m-3); exchangeable cations (Ca2+, Mg2+, K+, and Na+; meq 100 g-1); and soil elemental concentrations (Fe, Mn, Mg, Ca, K, Na, Al, Si, Ti, and S; ppm). The authors acknowledge financial support from French national grant CNRS/INSU EC2CO-Biohefect/Ecodyn//Dril/MicrobiEen(BurLuMic) and the IRD International Joint Laboratory LUSES. Essential support with microbiological analyses was provided by the Lao-Oxford-Mahosot-Wellcome Trust-Research Unit (LOMWRU), Vientiane, Lao PDR, funded by the Wellcome Trust [Grant number 106698/Z/14/Z]. The Department of Agricultural Land Management (DALaM) of the Ministry of Agriculture and Forestry of Lao PDR facilitated access to the field and provided invaluable support with soil analyses. IRD staff in Laos would like to sincerely thank Mr Outhong Sengouthai, owner of the paddy field as well as village authorities to have permitted us to make field measurements in Ban Nabone. KP would like to acknowledge financial support for her PhD from Campus France (BGF) and expresses her gratitude to IRD GET and iEES-Paris staff in France and Lao PDR for assistance and guidance with her work.
