The adoption of the following two practices helped to increase the amount of food produced per unit area of farmland: four-field crop rotation and selective livestock breeding.

It was during the 16th century that new agricultural technologies innovated the way farm fields were worked. The four-field crop rotation that allowed farmers to diversify the kind of crops that grew in the same place, represented a great advancement for agriculture.
