The agricultural method characterized by dividing arable land into three parts is a crucial aspect of medieval agricultural history. Two fields are planted with different crops, such as wheat or rye and oats or barley, while the third lies fallow. This rotation allows the soil to replenish its nutrients, enhancing long-term productivity.
This rotational approach offered significant advantages over previous two-field systems. It increased the amount of land under cultivation at any given time, leading to greater yields and a more secure food supply. The diversification of crops also contributed to a more balanced diet for the population and provided fodder for livestock, supporting animal husbandry. The system’s implementation played a significant role in supporting population growth and the development of medieval society.
