Definition of Agricultural Waste

A general definition of 'agricultural waste' is not available in the literature. According to the United States Environmental Protection Agency (USEPA), agricultural waste is the byproducts generated by the rearing of animals and the production and harvest of crops or trees. Animal waste, a large component of agricultural waste, includes waste (e.g., feed waste, bedding and litter, and feedlot and paddock runoff) from livestock, dairy, and other animal-related agricultural and farming practices. Organisation for Economic Cooperation and Development (OECD) defines 'agricultural waste' as waste produced as a result of various agricultural operations including manure and other wastes from farms, poultry houses and slaughterhouses; harvest waste; fertilizer run-off from fields; pesticides that enter into water, air or soils; and salt and silt drained from fields. In the context of this chapter, agricultural waste is defined as waste in the form of the crop residues in the farm, manure from livestock operations, including dairy and piggery effluent, and poultry litter.
