Crop Response to Soil Salinity on the Delmarva Peninsula with Drone and Soil Data

2.1 MB of integrated data from 10 field sites (S1-S10) on the Delmarva Peninsula, used to evaluate crop responses to coastal soil salinity. The dataset includes Normalized Difference Vegetation Index (NDVI) from drone imagery, log-transformed soil sodium (lnNa), and digital elevation model (DEM) data, aggregated into 5x5 meter grid points. It was authored by JARROD MILLER and last updated on 2026-05-08.

Use Cases

• Mapping spatial relationships between elevation and soil sodium accumulation based on DEM and lnNa data.
• Identifying threshold responses and transition zones for crop stress using integrated NDVI and soil salinity metrics.
• Delineating site-specific management zones for salinity in humid coastal agricultural systems.
• Analyzing lead-lag relationships between root-zone salinity and canopy-level stress indicators.

Strengths

• Integrates three distinct data types: drone-derived NDVI, soil chemistry (lnNa), and topographic (DEM) data.
• Data is aggregated into a consistent 5x5 meter fishnet grid across 10 field sites, facilitating spatial analysis.
• Released under a permissive CC0-1.0 license, allowing for unrestricted use.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to its collection on the Delmarva Peninsula.
