Gridded Crop Yield Maps from 40+ Maryland Fields

A multi-year archive of gridded yield data derived from yield monitor data acquired from over 40 production fields in Beltsville, Maryland. The data was processed through geographic projection, outlier removal, and spatial interpolation using block Kriging to create yield maps in common file formats. This research is a contribution from the USDA-supported Long-Term Agroecosystem Research (LTAR) network.

Use Cases

• Analyze spatial yield variability within and across the 40+ production fields using the gridded, interpolated yield maps.
• Apply block Kriging techniques to the yield monitor data for comparative studies in spatial interpolation methods.
• Investigate long-term yield trends for agroecosystem research as part of the LTAR network's objectives.
• Integrate the gridded yield maps with other geospatial data for precision agriculture and farm management analysis.

Strengths

• Contains data from over 40 distinct production fields, providing a multi-field perspective.
• Data is processed and available as gridded, spatially interpolated yield maps in common, nonproprietary file formats.
• Part of the USDA-supported Long-Term Agroecosystem Research (LTAR) network, indicating a research-grade origin.

Limitations

• Specific temporal coverage, row count, column structure, and sample size are not provided in the input.
• Geographic scope is limited to fields in Beltsville, Maryland, which may limit generalizability to other regions.
• The raw yield monitor data required significant processing (outlier removal, interpolation), which may obscure original measurement nuances.
