America

CLIMATE Precipitation average of 20-35 in. Temperature from -40 F to 100F Prairie: Temp from 20-70, 10-30 inches Steppes: 10-20 inches Pampas: 64 Degrees Cold winters, dry, hot summers,

humidity

SOIL Dark and Deep Fertile upper layers High in calcium carbonate-good for

fertility Chernozem-phosphorus and ammonia,

really fertile. Loess-windblown silt, sometimes

derived from glacial deposits(MS river)

LIMITING FACTORS Human agricultural use Low precipitation levels Fires Absence of tree cover
