Pastoral farming (also known in some regions as ranching, livestock farming or grazing) is aimed at producing livestock, rather than growing crops. Examples include dairy farming, raising beef cattle, and raising sheep for wool. In contrast, arable farming concentrates on crops rather than livestock. Finally, mixed farming incorporates livestock and crops on a single farm. Some mixed farmers grow crops purely as fodder for their livestock; some crop farmers grow fodder and sell it. In some cases (such as in Australia) pastoral farmers are known as graziers, and in some cases pastoralists (in a use of the term different from traditional nomadic livestock cultures). Pastoral farming is a non-nomadic form of pastoralism in which the livestock farmer has some form of ownership of the land used, giving the farmer more economic incentive to improve the land. Unlike other pastoral systems, pastoral farmers are sedentary and do not change locations in search of fresh resources. Rather, pastoral farmers adjust their pastures to fit the needs of their animals. Improvements include drainage (in wet regions), stock tanks (in dry regions), irrigation and sowing clover. Pastoral farming is common in Argentina, Australia, Brazil, Great Britain, Ireland, New Zealand, and the Western United States and Canada, among other places. Characteristics There are many factors that are taken into account to decide what type of farming should take place on a certain area of land including, topography, altitude, exposure, and rainfall. Soil plays a large role in determining how land will be used. Mollisol lands are typically described as semi-arid to semi-humid areas that are grassy and wet. This is where most intensive cattle operations occur which produce beef and dairy. Although a majority of pastoral farming is conducted in Mollisol lands, pastoral farming can also be found in areas with soil made up of Entisol, Aridisol or Alfisol. Aside from soil order, pastoral farming is more likely to be found than arable farming in areas with steep slopes, cold strong winds and a wet climate. All of these conditions are more advantageous to raising livestock than crops. Raising of sheep is often found in cooler regions with steep hills and above-average rainfall. The wetness of the area and incline would make it unsuitable to grow crops. A similar conclusion is drawn by looking at dairy farms which are often found in warm wet climates.
