Extensive farming (as opposed to intensive farming) is an agricultural production system that uses little inputs on vast areas of land, such as the Great Plains. Extensive farming most commonly refers to sheep and cattle farming in areas with low agricultural productivity, but can also refer to large-scale growing of wheat, barley and other grain crops in areas like the Murray-Darling Basin. Here, owing to the extreme age and poverty of the soils, yields per hectare are very low, but the flat terrain and very large farm sizes mean yields per unit of labour are high. Nomadic herding is an extreme example of extensive farming, where herders move their animals to use feed from occasional rainfalls.
Intensive farming (or Capital Intensive farming) has a large investment and usually works with alot of food production at one time, Bernard Mathews is an example of a capital intensive farming system, with lots of animals in a small space.
