What types of farming did the peasants of the middle ages do?
nic 256 was on the right track with his answer. In the earlier parts of the Middle Ages, the peasants ran a two-field rotation. This meant farming one field while using the other for grazing, and then flipping them the next year. Later they moved to a 3-field system. The farmed one with their main crop, farmed the second with a complimentary crop (this helps retain certain nutrients in both fields), and used the third for grazing. Then they rotated each year. This 3-field system of farming was the most efficient way to farm and was the most environmentally friendly during the Middle Ages.
