Changes have been made to meet the needs of tenant farmers and the requirement would not be introduced until 2030, giving farmers time to adjust with support from the Welsh Government.
Mae newidiadau wedi cael eu gwneud er mwyn diwallu anghenion ffermwyr tenant, ac ni fyddai'r gofyniad yn cael ei gyflwyno tan 2030, gan roi amser i ffermwyr addasu, gyda chymorth gan Lywodraeth Cymru.
