Modern agriculture in the United States is best described as
increasingly specialized (concentrating on limited numbers of crops or
types of animals). Although mixed crop and livestock farming still

animals. Examples include dairy farming, corn and soybean farms,
pig-raising operations, specialized vegetable farming around cities, and
large-scale wheat production.
