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 10 to 15% of the land in Wales. Planning applications and local development plans should include survey evidence when they cover grade 1, 2 or 3a land.
