Topsoil Salinity and Chemistry in the Tailan River Irrigation District, Xinjiang (2024)

April 20-21, 2024 survey of 118 sampling points in the Tailan River Irrigation District, Xinjiang, China, resulting in 807 soil samples. Author Qianxi ZHANG collected data on soil pH, electrical conductivity, moisture, total soluble salts, and eight major ions from 0-120 cm depths. This dataset provides spatial distribution characteristics of soil salinity to support land improvement and precise agricultural management.

Use Cases

• Model spatial distribution of soil salinity based on 118 georeferenced sampling points.
• Analyze relationships between soil electrical conductivity (EC) and major ion concentrations.
• Assess topsoil moisture content variation across different depths (0-120 cm).
• Support precision agriculture and land reclamation policy based on soil pH and total soluble salts data.

Strengths

• Data from 807 soil samples collected at 7 depths per point, providing vertical profile detail.
• Collection followed Chinese agricultural industry standard NY/T 395-2025 and FAO pretreatment procedures.
• Includes 118 qualified sampling points after data accuracy verification and parallel tests.

Limitations

• Row count and specific column names are unknown, limiting suitability assessment.
• Data is from a single two-day period in April 2024; seasonal variation is not captured.
• Geographic scope is limited to one irrigation district in Xinjiang.
