Designation for an agriculturally used area that is intended for resting. However, this also refers to the corresponding period of time. A vineyard fallow is necessary for at least one to three years after a vineyard has been grubbed up to ensure that new vines can thrive. Several years are necessary if the old vines had to be removed due to diseases caused by nematodes or viruses or because of stunted growth. The grubbing up is followed by a cover crop (short-time greening). This involves planting plants that root the soil well and enrich it with organic matter. The size of vineyards usually includes the fallow parts. An old term for an unused area of arable land or an area of v ines that is planted but unused is driesche.
