On-Farm Soil Test and Topographic Data for Legacy Phosphorus Study in Maryland, 2022

Caroline County, Maryland, USA, is the location for this dataset supporting spatial analysis of legacy phosphorus dynamics in the Lower Chesapeake Bay watershed. It includes tabular data, shapefiles, and raster maps derived from field measurements and Random Forest modeling. The dataset was created by MARYAM FOROUGHI and last updated in 2026, funded by USDA-NRCS and USDA-ARS projects.

Use Cases

• Modeling legacy phosphorus transport based on field soil test data and topographic metrics.
• Spatial analysis of soil properties using provided shapefiles and raster maps.
• Evaluating the effectiveness of conservation practices in the Lower Chesapeake Bay watershed.
• Training Random Forest models for predicting phosphorus dynamics from environmental variables.

Strengths

• Data integrates multiple sources, including on-farm soil tests and LIDAR-derived topographic metrics.
• Dataset is 115.9 MB and includes tabular data, shapefiles, and raster maps for comprehensive spatial analysis.
• Funded by USDA-NRCS and USDA-ARS, indicating institutional support for agricultural research.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
