Agricultural Land Classification (ALC) Grades - Post 1988 Survey (polygons)

Alternative title(s)

ALC Grades post 1988

Abstract

Agricultural Land Classification Grade and Job number for post-1988 ALC surveys for England Only. Polygons showing 5 classes of agricultural land plus classifications for urban and non-agricultural land. Grade one is best quality and grade five is poorest quality. A number of consistent criteria were used for assessment which include climate (temperature, rainfall, aspect, exposure, frost risk), site (gradient, micro-relief, flood risk) and soil (depth, structure, texture, chemicals, stoniness).

Lineage

Post 1988 Agricultural Land Classification (ALC) site data – scanned original paper maps and reports for individual sites surveyed in detail by the then Ministry of Agriculture Fisheries and Food (now the Department for Environment, Food and Rural Affairs (Defra)); which include subdivisions of Grade 3 Land between 1989 and 1999. Individual sites have been mapped at varying scales and level of detail from 1:5,000 to 1:50,000 (typically 1:10,000). This is the most detailed and up to date ALC dataset.
