2  Found in middle latitudes and prairie regions  Areas with moderate temps and precipitation  Organic decomposition is responsible for thick dark topsoil  Results  Soil generally high in nutrients

4  Mollisols cover 7% of the Earth’s ice free land surface.  Primarily in the middle latitudes  Large amounts in central/northern U.S.  Significant amounts of mollisols are also found in Eastern Europe, Central Asia, and even South America

5 U.S. land surface Mollisols are found in the continental U.S. in abundance. Most abundant soil order in the U.S. Covers 21.5% of U.S. land Most mollisols are found in central and western U.S.

6  Granular texture.  High amounts of organic decomposition  A - shows topsoil with thick dark organic matter  Mollisols are used for agriculture when soil isn’t at water table  Suitable for corn, soybeans, and grains  Also support grazing and pasture lands for livestock.

7  Mollisols are found in moderate climates  Mollisols are formed on top of glacial till and cover a large portion of the U.S. grainbelt  They are generally fertile  High absorption of H20. soil is often saturated in wet seasons.  High amounts of clay in subsurface horizons
