<b>Combining Subsurface Pipe Drainage with Organic Amendments to Regulate Soil Salinity an

A two-year field experiment data evaluating six treatments for ameliorating heavily saline-alkaline soil. The dataset includes measurements for soil electrical conductivity, pH, organic carbon, total nitrogen, microbial biomass, and enzyme activities. The data was authored by Kunyu Duan and last updated in May 2026.

Use Cases

• Modeling the relationship between subsurface pipe drainage and soil salt leaching based on electrical conductivity (EC) and pH data.
• Analyzing the impact of organic amendments on soil microbial activity based on microbial biomass carbon (MBC) and nitrogen (MBN) measurements.
• Comparing synergistic effects of combined treatments on soil enzyme activities such as S-CL, S-UE, and S-POD.
• Investigating changes in soil nutrient retention capacity based on microbial stoichiometric ratios (MBC:SOC and MBN:TN).

Strengths

• Data is derived from a two-year field experiment with six distinct treatment groups, including a control.
• Dataset reports specific percentage changes for key metrics, such as a 12–16% reduction in EC and 10–29% increases in MBC and MBN for the most effective treatment.
• License is CC-BY-4.0, permitting broad reuse with attribution.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (35.1 KB), indicating a limited scope likely focused on summary or experimental results.
