1826
Factors influencing location of agriculture • Climate and natural environment Urban market • Culture • Economic factors High transportation cost items (vegetables, eggs, dairy, flowers) Intensive land use – high land rent Medium transportation cost items (corn, soybeans, mixed farming) More extensive land use – medium rent Lowest transportation cost items (forestry, wheat, livestock ranching) Most extensive land use – lowest land rent Simplified von Thünen model of agricultural land use (1826)
Bid Rent Theory Land closer to the city center costs more. Land farther away costs less.
