Greenhouse Gas Emissions from Four Linseed Genotypes at Two UK Field Sites, 2024-2025

Conor Walthall's dataset contains measurements of greenhouse gas emissions from four elite linseed genotypes at two UK field sites in 2024 and 2025. The data includes weekly GHG fluxes, soil temperature, volumetric soil moisture, and crop height, analyzed with ANOVA and linear mixed-effects models. The study found significant site- and year-driven differences in emissions, with genotype VT50 showing a significant methane sink in 2025.

Use Cases

• Modeling the relationship between crop height and CO2 fluxes based on the described positive correlation.
• Analyzing the interactive effects of soil temperature and moisture on CH4 and N2O fluxes as mentioned in the description.
• Comparing cumulative GHG emissions across different field sites and years to assess environmental dominance over genotype.
• Evaluating the potential of specific linseed genotypes, like VT50, as low-emission crops based on its methane sink behavior.

Strengths

• Includes data from two distinct UK field sites and two growing seasons (2024, 2025), allowing for temporal and spatial comparison.
• Measures multiple variables: GHG fluxes (CO2, CH4, N2O), soil temperature, volumetric soil moisture, and crop height.
• Analysis includes statistical methods like ANOVA and linear mixed-effects models, as described.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is contained in a DOCX file (4.1 MB), which may require extraction and formatting for analysis.
