Root Zone Temperature Effects on Crop Yield and Growth from Greenhouse Experiments

Ken Uhlig's dataset from 2026 quantifies the effects of underground HVDC cable-induced soil warming on agricultural systems. It contains results from a controlled greenhouse experiment using a HeAted soiL Monolith (HAL-M) system simulating heating at 1.4 m depth. The data covers a sequential crop sequence of spring barley, sugar beet, spring wheat, and lucerne grown on two soils under three water regimes.

Use Cases

• Modeling crop yield response to soil warming based on root zone temperature data.
• Analyzing crop-specific nutrient composition changes under elevated soil temperatures.
• Assessing root growth intensity variations across different soil types and water regimes.
• Evaluating mitigation strategies for underground cable routing based on experimental yield impacts.

Strengths

• Data is derived from a controlled greenhouse experiment simulating real-world cable heating at 1.4 m depth.
• Covers a sequential crop sequence of four species (spring barley, sugar beet, spring wheat, lucerne) on two soils under three water regimes.
• Employs a group-specific ratio normalization to isolate heat-induced responses across different crops.
• Dataset is licensed under CC-BY-4.0, allowing for open reuse and modification.

Limitations

• The dataset is very small at 5.9 KB, indicating limited scope or a summary-level dataset.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
