Arable farming is influenced by physical and human factors. Crops such as wheat or oats require a warm climate and fertile soil to flourish. They also require flatland that allows the use of combine harvesters and other machinery. Most arable farmers use crop rotation to maximize their yields.
Arable farming deals mainly with cultivating crops on viable land. Crops grown by arable farming include vegetables, cereals and plants that produce cloth or oils.

The best known type of integrated mixed farming is probably the case of mixed crop-livestock systems. Cropping in this case provides animals with fodder from grass and nitrogen-binding legumes, leys (improved fallow with sown legumes, grasses or trees), weeds and crop residues.
Agriculture as practiced in one place by a settled farmer in which fields are not rotated is called sedentary agriculture. The term was used for primitive agriculturists in tropical Africa who farmed the same piece of land indefinitely in contrast to shifting cultivation.
