Land is categorised into one of the following grades:

  • grade 1: excellent quality agricultural land
  • grade 2: good quality agricultural land
  • grade 3a: good to moderate quality agricultural land
  • grade 3b: moderate quality agricultural land
  • grade 4: poor quality agricultural land
  • grade 5: very poor quality agricultural land

Planning policy defines grades 1 to 3a as the ‘best and most versatile’ agricultural land. This is about 7% of the land in Wales. Planning applications and local development plans should include survey evidence when they cover grade 1, 2 or 3a land.
