When talking about agricultural production in the feudal world, we soon remember that working on the land sought to meet basic needs. Unlike in other times, medieval agriculture had a low productive performance that limited the occurrence of natural exchanges and trade. In general, this subsistent characteristic is related to the poor quality of the seeds used and the limitation of the instruments and techniques of the time.
Despite the relevance of these factors, we must take into account that the medieval peasants also used the system of crop rotation. In this technique, a lot of arable land was divided into three equivalent portions. In the first two, the servant established the planting of two distinct cultures. The remaining lot was not used, so that the land plot was not completely worn out.
