Why temperate zone is called graneris of the world?
Answers
Temperate grasslands are located in the interior parts of continents between 35 to 55 latitudes in the both hemispheres.
They experience an extreme or continental type of climate.
Vegetation is chiefly prophytic in nature, that is, these grasses are capable of regenerating themselves even after a destructive fire.
The soils of these regions are black earths called chernozems.
Most of the grasslands have been converted to wheat farms, especially in the Northern Hemisphere.
Farms are large in size ranging on an average 400 hectares. Wheat is the main crop though maize, beans and potatoes are also grown. Farming is mainly mechanised because farm hands are scarce and landholding are large. Yield per acre is low but Yield per person is high. The grain is mainly cultivated for export.
Thus, Temperate grasslands have become the granaries of the world.
