Soil Texture & Bulk Density

This dataset contains soil texture (percentages of sand, silt, and clay) and bulk density (g/cm³) measured from 335 soil samples collected across Mississippi and Texas. Soil texture was determined using a Mastersizer 3000 laser diffraction instrument, while bulk density was measured using the core method. These parameters are fundamental physical properties of soil and are commonly used to characterize soil structure, porosity, and compaction.

One primary application of this dataset is to provide input variables for the Rosetta Pedotransfer Function models, which are used to estimate key soil hydraulic parameters such as field capacity, permanent wilting point, and the soil water retention curve. Specifically, Rosetta Model 2 can be applied using soil texture data (percentages of sand, silt, and clay), while Rosetta Model 3 incorporates both soil texture and bulk density together to improve predictions.

This dataset can thus support hydrological modeling, soil physics research, and environmental management by providing key inputs for estimating soil hydraulic properties.
