EXTENSIVE MECHANISED GRAIN CULTIVATION

EXTENSIVE MECHANISED GRAIN CULTIVATION
A recent development in the continental lands of the mid­latitudes, which were once roamed by nomadic herdsmen, this kind of agriculture was motivated by the invention of farm machinery. Farmers are able to cultivate grain on a large scale, and there is specialisation in wheat monoculture in many regions. The Eurasian Steppe, the Canadian and American Prairies, the Pampas of Argentina, the Veld of South Africa, the Australian powns, and the Canterbury Plain of New Zealand are the major regions practising this type of agriculture. It is characterised by large farms, use of mechanised cultivation, monoculture of wheat (though other crops are becoming important), low yield per acre but high yield per person.
