Shifting cultivation (or slash and burn) is a system in which forests are burnt, releasing nutrients to support cultivation of annual and then perennial crops for a period of several years. [144] Then the plot is left fallow to regrow forest, and the farmer moves to a new plot, returning after many more years (10–20).
When plants of the same species are cultivated in rows or other systematic arrangements, it is called crop field or crop cultivation. Most crops are harvested as food for humans or fodder for livestock. Important non-food crops include horticulture, floriculture, and industrial crops.
The Moors may have also brought rice to Sicily, with cultivation starting in the 9th century, [37] where it was an important crop [36] long before it is noted in the plain of Pisa (1468) or in the Lombard plain (1475), where its cultivation was promoted by Ludovico Sforza, Duke of Milan, and demonstrated in his model farms.

The system (wheat, turnips, barley and clover) opened up a fodder crop and grazing crop allowing livestock to be bred year-round.

As maize cultivation became more important, communities became larger and more settled, although hunting and gathering wild foods remained important. Several of the agricultural towns in the Southwest, such as Casa Grande and Casas Grandes plus Pueblo and Opata settlements may have had populations of 2,000 or more at the peak of their influence.
Many have important trade contacts and trade items that they can produce because of their special skills or special access to resources valued in the marketplace. [3] Subsistence farming today is most common in developing countries. [3]
