Give geographical reason: Extensive agriculture is a commercial type of agriculture.

Answer: Because it is practised on very large farms with machinery to produce crops mainly for sale.

• Extensive farming is carried out in sparsely populated temperate grasslands such as the Prairies, Pampas, Steppes, Veld and Downs.
• Farms are very large (hundreds of hectares) and are worked with tractors, combines and other machines, with little labour.
• Usually a single crop such as wheat is grown on a large scale; yield per hectare is low but total output and yield per worker are high.
• The produce is far more than local needs and is sold in national and international markets, so it is commercial agriculture.
