Sources of Agricultural Land Classification (ALC) information.

The only way to accurately determine the agricultural quality of land is through a detailed ALC survey in accordance with the Ministry of Agriculture, Fisheries and Food (MAFF) ALC guidelines 1988 (external link).

Provisional ALC Maps have been produced for Wales. These maps predate the current 1988 ALC guidelines and are not suitable for assessing individual sites.

ALC information is also available from the Land Quality Advisory Service.
