Term

Alfisol

(Definition)

Definition

found in semiarid to moist areas Come from leached clay minerals make up 10% of of worlds surface

(Name the soil order)

Term

Andisol 

(Definition)

Definition

- high water and nutrient holding capacity

- found in cool areas with moderate precipitation especially near volcanic materials

- highly productive soils

-make up 1% of world

(name soil order)

Term

Aridisol

(Definition)

Definition

- lack of moisture restricts rapid weathering 

- common in deserts of the world

-accumulates gypsum, salt and calcium carbonate (which are easily leached from soils)

- make up 12% of world 

(name the soil order)

Term

Entisol

(Definition)

Definition

- little or no evidence of horizon development

- occur in areas where parent material had been recently deposited or where erosion is faster than soil development.

- have ochric epipedon

-make up 8% of world

-examples are dunes, or floodplains

(name soil order)

Term

Gelisol

(Definition)

Definition

- have permafrost near soil surface

-common in higher latitudes and elevations

- make up 9% of world soil 

(name soil order)

Term

Histosol 

(Definition)

Definition

- high organic matter content

- saturated year-round 

- form in decomposed plants that accumulate more than they decay

-make up 1% of worlds soils 

(name soil order)

Term

Inceptisol

(Definition)

Definition

-from semi-arid and humid environments

-moderate weathering and development

- Lack of development due to erosion, resistant PM, or recent deposition

- make up 9% of the worlds soils

(name soil order)

Term

Mollisol

(Definition)

Definition

-high organic matter in upper horizons

-very fertile

- form under grass from climates that have moderate seasonal moisture deficit

- make up 7% of the worlds soils

(name soil order)

Term

Oxisol

(Definition)

Definition

- highly weathered soil from tropic to sub-tropic areas

-have indistinct horizons 

- low activity minerals (ir kaolinite, quartz and iron oxides)

- low natural fertility and low ability to retain additions and fertilizer

- make up 8% of worlds soils

(name soil order)

Term

Spodosol

(Definition)

Definition

- form form weathering process that strip organic matter

-commonly occur in areas course-textured deposits, forests and humid regions

-tend to be acidic and infertile

- make up 4% of the worlds soils

(name soil order)

Term

Ultisol

(Definition)

Definition

- high leaching and weathering

leaving clay-enriched subsoil

- found in humid areas

-acid soils with nutrients found in top

few inches of soil

-make up 8% of worlds soils  

(name soil order)

Term

Vertisol

(Definition)

Definition

-high content of expanding clays 

- swell when wet, transmit water slowly meaning slow leaching

-high in natural nutrients

- make up 2% of the worlds soils
