ALCC11594: Detailed Agricultural Land Classification Survey Maps and Reports (1989-1999)

Post-1988 Agricultural Land Classification (ALC) survey data for the Naseby, Portly Ford Farm site, collected by the Ministry of Agriculture, Fisheries and Food between 1989 and 1999. The dataset includes scanned original paper maps and survey reports, with some surveys providing unedited sample point soils data and soil pit descriptions. Maps were created at scales from 1:5,000 to 1:50,000, typically 1:10,000, and use the grading methodology from the 'Agricultural Land Classification of England and Wales' guidelines.

Use Cases

• Classify agricultural land capability based on the detailed grading methodology described in the survey reports.
• Analyze soil characteristics and variability using the available unedited sample point and soil pit description data.
• Integrate historical land classification maps into modern GIS systems for temporal land-use change analysis.

Strengths

• Data collection spans a defined 10-year period from 1989 to 1999.
• Surveys provide detailed subdivision of Grade 3 land into subgrades 3a and 3b.
• Includes original scanned maps and reports, preserving the primary survey record.

Limitations

• Last update date is unknown; freshness unverified.
