The existing literature on the economy of medieval England views the practice of convertible husbandry as a more efficient alternative to regular common fields. The article challenges this view by measuring the productivities of the systems, which are found to be approximately equivalent. In interpreting this finding, it is suggested that edaphic conditions and wrongful managerial practices account for the poor performance of convertible husbandry during the Middle Ages, whereas the greater productivity achieved by the system in the early modern period is attributed to the introduction of fodder legumes, such as clover, which were absent in previous centuries.
