This is also defined in section 1 as follows:

rural land means land that is used or apparently intended to be used for gain or profit for grazing of livestock, dairying, poultry farming, viticulture, orcharding, beekeeping, horticulture, the growing of crops of any kind, vegetable growing or any other purpose declared by the regulations to be a rural purpose.

Note that the definition is very broad with ..intended to be used.. and ..the growing of crops of any kind, .. This means that almost all rural properties with some sort of agricultural land use or intended to be so used is rural land. If a hobby farmer sells his/her livestock on a regular basis then that use should come under the clause ..used for gain or profit... even though the enterprise is being run at a loss.
