WORLD HISTORY

Detailed explanation-1: -In the old two-field system half the land was sown to crop and half left fallow each season; in the three-field system, however, only a third of the land lay fallow.

Detailed explanation-2: -This meant farmers had to break their holdings into three fields–one to be planted with wheat or rye in the fall, for human consumption; a second to be used in the spring to raise peas, beans, and lentils for human use and oats and barley for the horses.

Detailed explanation-3: -The three-field system of crop rotation was employed by medieval farmers, with spring as well as autumn sowings. Wheat or rye was planted in one field, and oats, barley, peas, lentils or broad beans were planted in the second field. The third field was left fallow.

Detailed explanation-4: -The three-field system had great advantages. First, it increased the amount of land that could be planted each year. Second, it protected farmers from starvation if one of the crops failed.

Detailed explanation-5: -The three-field system predominated in Russian peasant agriculture until the Stalin era. Plowland was divided into three sections: each year one section was sown in the winter, a second was sown to another grain in the spring, and a third was left fallow to restore its fertility.
