3Various kinds of maizeOxen pull a plow in PortugalShifting Agriculture-Slash & Burn, Patch or MilpaTropical areas-red soil is heavily leached.Plot of land is cleared by burning-ash replenishes soil.A type of crop rotation-tubers in warm tropics, grains in humid subtropics, fruit in cooler regions.Not nomadic-central village with parcels of land worked in successionConserves forests & soil, requires organization
4Shifting Cultivation is usually practiced in tropical areas with poor soils-soil fertility is maintained by rotating fields-note burned stumps with corn and beans interplanted. (land cleared is called Swidden)Requires less intense farming or work-but supports a lower population density than traditional farming.To outsiders Slash and Burn appears to be destructive, wasteful and disorganized-there are no neat rows of monocrops-no carefully plowed soil-Instead there are a variety of crops grown next to each other in what appears to be a jumble.
