Fallow is a farming technique in which arable land is left without sowing for one or more vegetative cycles. The goal of fallowing is to allow the land to recover and store organic matter while retaining moisture and disrupting the lifecycles of pathogens by temporarily removing their hosts.
It is a technique often used in crop rotation. Existing weeds may be affected by predators and pests. These, along with the use of green manure can ensure the restoration of depleted nutrients to the soil composition before another crop cycle.
