The use of mechanized farming techniques is well suited to geographic areas that c. have large expanses of flat land. Regions such as the Canadian Prairies is a large expanse of flat land and as such easily supports mechanization in planting crops such as wheat. Mechanization in agriculture would be hampered in areas that experience frequent flooding as equipment could get stuck in mud or suffer other water damage.
