Abiotic CO2 Emissions from Agricultural Soils Treated with Gallic Acid

An experiment measured CO2 emissions from 4-hour incubations of soil from 5 different management systems, 18 archived benchmark soils from sites across the U.S., and 4 samples of reagent-grade metal oxides. Treatments included water, pH 4 phthalate buffer, glucose, or gallic acid to understand abiotic CO2 sources. The data was published by the Department of Agriculture and last updated on March 13, 2026.

Use Cases

• Modeling abiotic CO2 production rates based on soil type and treatment conditions mentioned in the description
• Comparing CO2 emissions from different agricultural management systems referenced in the experiment
• Analyzing the effect of phenolic compounds like gallic acid on soil redox reactions and carbon cycling
• Benchmarking soil reactivity using archived soil samples from across the U.S.

Strengths

• Experiment includes 18 archived benchmark soils from sites across the U.S.
• Data covers 4 distinct chemical treatments (water, buffer, glucose, gallic acid).
• Published under a CC0-1.0 public domain license for unrestricted use.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
