True or False: The heavy plow helped increase agricultural production in medieval Northern Europe.

The story behind the answer

Equipped with an iron coulter, cutting share, and curved moldboard, the heavy plow could slice into and overturn the dense, wet clay soils common in the north. Turning the soil improved aeration and drainage, buried weeds, created deeper seedbeds, and made previously marginal land arable—raising yields and expanding the area under cultivation.

Its impact multiplied when paired with the padded horse collar and horseshoes, letting horse teams pull faster and longer than oxen. Combined with the spread of three-field crop rotation, these tools fueled a “medieval agricultural revolution”: population growth, new villages, and the consolidation of open-field systems across Northern Europe.
