This led to the clearing of northern European forests and an increase in agricultural production, which in turn led to an increase in population.<ref name=Backer>{{cite web |url= |title=Part 1 – Medieval European history |author=Backer, Patricia |publisher=San Jose State University |accessdate=24 April 2013 |work=History of Technology}}</ref> At the same time, farmers in Europe moved from a two field [[crop rotation]] to a three field crop rotation in which one field of three was left fallow every year. This resulted in increased productivity and nutrition, as the change in rotations permitted [[nitrogen-fixing]] [[legumes]] such as peas, lentils and beans. Improved [[horse harness]]es and the [[whippletree (mechanism)|whippletree]] further improved cultivation.<ref name=Backer/> [[Watermill]]s were introduced by the Romans, but were improved throughout the Middle Ages, along with [[windmill]]s, and used to grind grains into flour, to cut wood and to process flax and wool.<ref>{{cite book |url= |title=Daily Life in the Middle Ages |author=Newman, Paul B. |pages=88–89 |publisher=McFarland |isbn=0786450525 |year=2001}}</ref>
Crops included wheat, [[rye]], barley and [[oats]]. Peas, beans, and [[vetches]] became common from the 13th century onward as a [[fodder crop]] for animals and also for their [[nitrogen-fixation]] fertilizing properties. Crop yields peaked in the 13th century, and stayed more or less steady until the 18th century.<ref name=Campbell1>{{cite journal |last=Campbell |first=Bruce M. S. |author2=M.
