Fallowing

Fallowing is a farming technique in which arable land is left without sowing for one or more vegetative cycles, so that the soil can recover and build up organic matter while maintaining moisture levels; the practice also helps interrupt pest cycles and eliminate soil-borne pathogens by removing their host plants. Historically, farming systems incorporated fallowing as a standard practice, with farmers leaving certain fields unseeded each year, but modern intensive agriculture, particularly the adoption of cover crops as an alternative, has significantly reduced fallow acreage. Fallows have long been a primary habitat for farmland bird populations, so the decline of these uncultivated areas has contributed to reduced biodiversity in agricultural regions.
