Nutrient Leaching from Poultry Litter-Amended Soils with Biochar and Chemical Amendments

An in-situ pot experiment on coarse-textured soil with corn measured nitrate, phosphate, and dissolved organic carbon in leachate across five rainfall events. The dataset compares six treatments, including poultry litter alone and with biochar, alum, or iron sulfate amendments. The data was published by Soura Shuvra Gupta on figshare in March 2026.

Use Cases

• Compare the effectiveness of biochar versus conventional chemical amendments for nutrient retention based on the described treatment results.
• Model the relationship between dissolved organic carbon and nutrient leaching based on the reported significant correlations.
• Assess the impact of soil amendments on crop yield in the context of nutrient leaching based on the grain yield results mentioned.
• Analyze nutrient loading trends across multiple rainfall events based on the cumulative average reductions reported for different amendments.

Strengths

• Includes specific concentration ranges for nitrate and phosphate across multiple treatments, e.g., 0.53–51.5 mg L⁻¹ for NO₃-N.
• Reports quantitative results from a controlled experiment with six distinct treatments and five sampling events.
• Provides statistical correlations between dissolved organic carbon and nutrients, e.g., r = 0.83 for DOC and PO₄-P.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 14.7 KB, indicating limited scope.
