Income Tax Deduction for Urban Farmers who try to and/or do use their homes within Urban areas as farms.
As defined by the USDA on the website.
Urban agriculture is loosely defined as the production, distribution, and marketing of food and other products within the geographical limits of a metropolitan area. This includes community and school gardens, backyard and rooftop plots, and non-traditional methods of caring for plants and animals within a constrained area. Some definitions also include farms that supply to urban farmers markets, community supported agriculture, or farms located within metropolitan green belts.
