Fallow water retention

Japanese: 休閑保水 - きゅうかんほすい
Fallow water retention

...In these places, in order to retain the little rainfall in the soil and make effective use of it, the land was left fallow for a year or more, during which time the topsoil was often cultivated shallowly with a plough to cut the soil's capillaries and suppress evaporation and retain moisture, and millets, beans, and wheat were cultivated the following summer, or wheat and oats in the winter. In arid regions where irrigation water is not available, such as Southwest Asia, Northwest India, and the northern Mediterranean, fallow farming, which retains moisture from the little rainfall, made it possible to cultivate crops, and together with irrigation farming, fallow farming supported the construction of ancient civilizations in these regions. A typical example of fallowing for weed control is the three-field farming system (three-field system) under the open land system in feudal Europe.
