Crop Yield and Root Growth Responses to Soil Warming from HVDC Cables

An integrated dataset from a greenhouse experiment assesses the effects of elevated root zone temperature, simulating underground HVDC cables, on four crops. The data includes measurements of plant growth, root development, yield, and nutrient concentrations across two soil types and three water regimes. The dataset, created by Ken Uhlig and last updated in May 2026, provides a framework for evaluating agricultural risks of energy infrastructure.

Use Cases

• Modeling crop yield response to soil warming based on experimental temperature manipulation data.
• Analyzing root growth intensity changes under elevated soil temperatures across different crops.
• Investigating trade-offs between crop yield and quality parameters like protein and sugar content under warming.
• Assessing the persistence of soil heating effects over sequential crop growth phases mentioned in the description.

Strengths

• Data covers a sequential crop sequence of four species (spring barley, sugar beet, spring wheat, lucerne), enabling comparative analysis.
• Experiments were conducted under controlled greenhouse conditions on two contrasting soils and three water regimes, suggesting controlled variability.
• The dataset applies a group-specific ratio normalization to isolate heat-induced responses across the crop sequence.

Limitations

• The dataset is small (11.0 KB), indicating limited scope and likely a summary or processed results rather than raw observations.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
