Farms can be categorized as big, medium, small, or marginal depending on their size. Big and medium farms employ mechanized and commercial production systems focused on maximum output through green revolution practices with little marketing strategy. They generate profit through commercial crops but carry diversified and risk-prone practices. Modern big farms specialize in fields, gather market intelligence, and utilize marketing strategies as part of high-tech, scientific, standardized, and qualitative precision farming approaches compared to old practices.
