Soil Hydraulic Properties from Centrifuge Method in Mississippi and Texas, 2022-2025

Van Genuchten–Mualem soil water retention parameters estimated using the centrifuge method. The dataset includes residual and saturated water content, scaling and fitting parameters, and plant-available water metrics like field capacity and permanent wilting point. Authored by Yasas Gamagedara and last updated in May 2026, the data originates from soil samples collected in Mississippi and Texas, USA.

Use Cases

• Calibrating soil water retention models based on van Genuchten parameters like θr and θs.
• Estimating plant-available water content for irrigation planning based on the AWC metric.
• Comparing spectroscopy-based estimation methods against traditional pedotransfer functions using parameters like α and n.
• Analyzing soil pore structure and drainage characteristics based on the shape factor m and field capacity FC.

Strengths

• Includes key van Genuchten–Mualem parameters (θr, θs, α, n, m) essential for hydraulic modeling.
• Provides derived agricultural metrics like Available Water Content (AWC), Field Capacity (FC), and Permanent Wilting Point (PWP).
• Data collection uses the standardized centrifuge method for estimating soil hydraulic properties.
• Covers a defined geographic area (Mississippi and Texas, USA) and time range (2022-2025).

Limitations

• The dataset size is listed as 0.0 B, indicating a very limited scope or potential placeholder status.
• Column-level documentation is absent; field semantics and data structure must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
