Data Sheet 1_Optimizing planting density for enhancing the synergistic effect of electroki

A research document detailing a 60-day experiment on optimizing tall fescue planting density for electrokinetic-phytoremediation of petroleum-contaminated soils. The study, authored by Peng Gao and last updated in April 2026, provides empirical data on removal rates, soil ion concentrations, zeta potential, and water-holding capacity across four density levels. It identifies an optimal planting density of 1 plant/cm² for the synergistic remediation effect.

Use Cases

• Modeling the relationship between planting density and petroleum removal rate based on the reported 60-day experimental results.
• Analyzing soil property changes (water-soluble ions, zeta potential) during the electrokinetic-phytoremediation process described in the study.
• Optimizing remediation protocols for contaminated sites based on the identified optimal planting density of 1 plant/cm².

Strengths

• Provides specific quantitative results, including petroleum removal rates of 2.37% to 6.75% for different planting densities.
• Identifies a clear optimal parameter (1 plant/cm² planting density) for the combined remediation technique.
• Released under a permissive CC-BY-4.0 license, allowing for reuse and redistribution.

Limitations

• The dataset is a 847.1 KB DOCX file, suggesting a limited scope focused on a single study's findings.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for computational analysis.
