Agricultural Land Classification detailed Post 1988 survey ALCB20588

所有者: 

Post 1988 Agricultural Land Classification (ALC) site survey data – scanned original paper maps and survey reports for individual sites surveyed in detail between 1989 and 1999 by the Ministry of Agriculture Fisheries and Food. Where Grade 3 is mapped this includes the subdivision of Grade 3 into subgrades 3a and 3b.

Surveys use the current grading methodology as described in "Agricultural Land Classification of England and Wales. Revised guidelines and criteria for grading the quality of agricultural land (MAFF, 1988)":http://webarchive.nationalarchives.gov.uk/20130402151656/http:/archive.d.... Individual sites have been mapped at varying scales and level of detail from 1:5,000 to 1:50,000 (typically 1:10,000). Unedited sample point soils data and soil pit descriptions are also available for some surveys.
