Soil Texture and Bulk Density Measurements from Mississippi and Texas, 2022–2025

Mississippi and Texas soil samples from 2022 to 2025 provide texture and bulk density data for 335 samples collected at 0-5 cm and 5-10 cm depths. Author Yasas Gamagedara measured soil texture using a Mastersizer 3000 laser diffraction instrument and bulk density using the core method. These fundamental physical properties characterize soil structure, porosity, and compaction.

Use Cases

• Estimating soil hydraulic parameters like field capacity and permanent wilting point based on soil texture percentages
• Improving predictions of the soil water retention curve based on combined soil texture and bulk density data
• Characterizing soil structure and compaction levels based on measured bulk density and texture
• Providing input variables for Rosetta Model 2 and Model 3 pedotransfer functions as described

Strengths

• 335 soil samples provide a substantial measurement base
• Data includes measurements for two distinct soil depths (0-5 cm and 5-10 cm)
• Specific, standardized measurement methods are documented: Mastersizer 3000 for texture and core method for bulk density

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data may reflect geographic bias inherent to the specific Mississippi and Texas collection sites
