Geog 107 Final Soils And Biomes

Front 1

Oxisols

Back 1

Tropical Soils, low in nutrients

Front 2

Aridisols

Back 2

Desert Soils, lack organic matter and can have lots of salts.

Front 3

Mollisols

Back 3

Grassland Soils, most important agricultural soils, very fertile.

Front 4

Alfisols

Back 4

Moderately weathered forest soils, productivity depends on moisture and temperature.

Front 5

Ultisols

Back 5

Highly Weathered Forest Soils, less fertile soil but nutrients can be restored by good crop management.

Front 6

Spodosols

Back 6

Northern coniferous forest soils, agriculture is difficult but can be greatly increased with the addition of lime to the soil.

Front 7

Entisols

Back 7

Recent undeveloped soils

Front 8

Inceptisols

Back 8

weakly developed soils from glacial till and outwash

Front 9

Gelisols

Back 9

Cold and frozen soils form in tundras at high latitude and/or elevation.

Front 10

Andisols

Back 10

Volcanic soils

Front 11

Vertisols

Back 11

Expandable clay soils

Front 12

Histosols

Back 12

organic soils from peat bogs and wetlands

Front 13

Equatorial and Tropical Rain Forest

Back 13

consistent day length, high isolation, surplus of precipitation. Soil: oxisols

Front 14

Tropical Seasonal Forest and Scrub

Back 14

Consistently warm tempts, wet and dry seasons, monsoons. Soils: Oxisols and utisols

Front 15

Tropical Savanna

Back 15

Consistently warm, seasonal precipitation and susceptible to drought and fire. Soils: Alfisols, utisols, and oxisols

Front 16

Midlatitude broadleaf and Mixed Forest

Back 16

Moist continental climates, temperate with a cold season. Soils: utisols and alfisols

Front 17

Needleleaf Forest and Montane Forest

Back 17

Short summer, cold winter, moderate precip, moist soils, frozen in winter. Soils: Spodosols, histosols, inceptisols.

Front 18

Temperate Rain Forest

Back 18

Mild summers and winters, winter wet, large surplus of precipitation. Soils: Spodosols and inceptisols

Front 19

Mediterranean Shrubland

Back 19

Hot dry summers, cool winters, water deficit in summer and surplus in winter. Soils: Alfisols and mollisols.

Front 20

Midlatitude Grasslands

Back 20

Temperate continental, summer and winter precipitation. Soils: mollisols and aridisols

Front 21

Warm and Cold Deserts

Back 21

Warm/cold, arid/semi-arid, chronic precipitation deficits. Soils: Aridisols and entisols

Front 22

Artic and Alpine Tundra

Back 22

Only 2-3 months above freezing with little precipitation. Soils: gelisols, histosols, and entisols.
