What impact did the moldboard (heavy) plow, the three-field system, and the increase use of iron horseshoe shod horses have on agricultural production and the quality of life of peasants during the European Middle Ages?

Answer: Quality of life Improved and Population grew.

Explanation:

The combination of these three inventions shaped what at the time was an agricultural revolution. The three-field system ensured soil fertility by rotating crops according to their soil nutrient usage. The moldboard plow allowed agricultural development in northern europe, which had rougher clay-like soil, more fertile but more difficult to break through that southern europe 's soil. The iron horseshoe protected the horse's hooves and thus meant an increase in productivity and usage of the animal. These factors enabled a population boom and the shift of urban centers from southern to northern europe. The availability of food also meant a better quality of life for the peasants, which could now more easily aquire food and feed themselves and their families.
