Although debatable,  many agricultural historians also believe that the introduction of convertible husbandry was brought about with the introduction of the turnip. They argue that "the lowly turnip made possible a change in crop rotation which did not require much capital, but which brought about a tremendous rise in agricultural productivity."Timmer, C. Peter, "The Turnip, New Husbandry, and The English Agricultural Revolution", The Quarterly Journal of Economics, Vol. 83, No. 3 (Aug., 1969), pp. 375-395 They believe that this "fodder" crop pushed agriculture in a direction in which "alternating" husbandry was seen as more efficient than traditional permanent pasture farming and jump-started the improvement of crop rotation and agricultural output versus capital. Although the turnip was popularized by Lord Townshend during the mid-18th century, the use of turnips being grown as fodder was seen as early as the 16th century. Convertible husbandry has been praised as the "best way to keep high fertility on both arable and pasture and to retain excellent soil texture and composition."Slicher van Bath, B.H., "Agrarian History of Western Europe", 1963, pp 249-54. It is adaptable to the type of land or soil at the location, and it provided a rotation between pasture and arable land which "not only produced the same amount of grain on a much reduced area, but broke the agrarian cycle of diminished returns by allowing more sheep and cattle to be kept, animals whose dung maintained" fertility.
Although often praised as increasing yields and efficiency, this is debatable. Yields were often poor in the late Middle Ages and approximately equivalent to regular common fields. It was not always adaptable to the type of land or soil at all locations. Kitsikopoulos claims it was the introduction of fodder legumes, such as clover, in the early modern period which eventually truly achieved greater agricultural productivity.
