sole

CONT: En partageant la sole de plantes sarclées entre betteraves et pommes de terre, on étale déjà davantage les besoins de main-d'œuvre, puisque la plantation et la récolte de ces deux plantes sont successives et non simultanées.

CONT: Arable land is usually worked on some fixed rotation based on the Norfolk four-course of roots, barley, clover, wheat. The portion of arable land under any one of the rotation crops is referred to as a ""break"", e.g., turnip break refers to all the land on the farm under that particular crop.
OBS: The terms ""field"" or ""fields"" are used in Canada to designate this concept. The term ""block"" is also used in England.
