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).

A new Predictive ALC Map (external link) has been produced for Wales. This map has been prepared in line with the current ALC guidelines.

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