(1)This section applies where a contract for a tenancy of an agricultural holding provides for the maintenance of specified land, or a specified proportion of the holding, as permanent pasture.
(2)Where this section applies, the landlord or tenant may, by notice in writing served on the other, demand a reference to arbitration under this Act of the question whether it is expedient in order to secure the full and efficient farming of the holding that the area of land required to be maintained as permanent pasture should be reduced.
(3)On a reference under subsection (2) above the arbitrator may by his award direct that the provisions of the contract of tenancy as to land which is to be maintained as permanent pasture or is to be treated as arable land and as to cropping shall have effect subject to such modifications as may be specified in the direction.
(4)If, on a reference under subsection (2) above, the arbitrator gives a direction reducing the area of land which under the contract of tenancy is to be maintained as permanent pasture, he may order that the contract of tenancy shall have effect as if it provided that on quitting the holding on the termination of the tenancy the tenant should leave—
(a)as permanent pasture, or
(b)as temporary pasture sown with seeds mixture of such kind as may be specified in the order,
such area of land (in addition to the area of land required by the contract of tenancy, as modified by the direction, to be maintained as permanent pasture) as may be so specified.
(5)The area of land specified in an order made under subsection (4) above shall not exceed the area by which the land required by the contract of tenancy to be maintained as permanent pasture has been reduced by virtue of the direction.
