Determination of soil moisture and texture impact on water origin in splashed soil-water droplets using deuterium-labelled water

The deposited data were collected as part of a research project entitled "Determination of soil moisture and texture impact on water origin in splashed soil-water droplets using deuterium-labelled water", funded by the National Science Centre, Poland, under the SONATA-18 project (no. 2022/47/D/ST10/02480). The aim of the project was to determine the origin of water in splashed droplets depending on soil properties such as moisture content, texture, and the energy of the impacting water drop. Water in these droplets originates from two sources: the drop hitting the soil surface and the water present in the soil. The use of isotopic labelling makes it possible to determine the proportion of water in splashed droplets derived from each source. The research was conducted at the Department of Environmental Biogeochemistry of the Institute of Agrophysics, Polish Academy of Sciences. The data was compiled on the basis of laboratory tests. Methods Isotope measurements were performed using a Delta V Advantage isotope ratio mass spectrometer (IRMS) (Thermo Scientific, USA) coupled with a vario PYRO cube elemental analyzer (Elementar, Germany). The δ2H value of the water sample was expressed relative to VSMOW (Vienna Standard Mean Ocean Water). Soil organic carbon concentrations were measured with a TOC-VCPH analyzer (Shimadzu Corp., Kyoto, Japan). The soil sand, silt, and clay contents weere determined with the laser diffraction method using a Mastersizer 2000 (Malvern, UK) with HydroG dispersion.
