### soil:

Frozen soil
* acts like saturated soil.
* are clearly important to cold regions, as is better representation of the snow pack.
* decrease the amount of infiltration, especially when ice content is high.
* is funny stuff since it still contains liquid water.
* play an important role in water redistribution on North Dakota landscapes.

Gleyed soil
* are neutral gray and occasionally greenish or bluish gray
  - or greenish or bluish gray
* has a gray, greenish gray, or bluish gray color.

### soil:

Good soil
* absorbs and retains water much better than poor soil.
* can provide a home for a billion nematodes per acre.
* drains well and can hold the oxygen and nutrients essential to growth.
* have significant pores.
* holds moisture and nutrients.
* is essential for most agriculture
  - to grow healthy plants that are able to survive pests and diseases
  - made up of older plants that have died
  - necessary for optimal plant growth
* is the foundation of a healthy lawn
  - legacy of pioneer grasses and plants now long gone
  - vital for healthy growth
* makes a difference in weed control.
* needs many pores, varying in size with some holding air and some water.
* produces the best plants, which bear the best crops.
* world of working microbes.

Grangemont soil
* are fine-silty and are on plateaus.
* contain fragic material and are on concave positions on plateaus.

Hard soil
* indicate low organic matter or high clay content.
* prevents the fine roots from growing.

Heavy soil
* Most heavy soils contain enough natural potassium for crop and pasture growth.
* can cause tubers to be small and rough.
* compacts in containers and slows water and oxygen from reaching the root zone.
* contain rhizomes.
* have relatively poor drainage and aeration capabilities.
* holds water for years and can cause potential flood risk.
* increase the difficulty of separating crowns when dug.
* needs more material than sandy soil.
* tend to become water-logged.

Heiden soil
* are on erosional uplands.
* occur on similar landscapes.

Hollis soil
* are shallow to bedrock
  - underlain by bedrock dominantly composed of granite, schist, and gneiss
* have rock fragments of gneiss, granite, or schist.

Hosmer soil
* are commonly on summits, shoulders, and backslopes of loess hills
  - on similar landform positions and have fragipans
* contain a fragipan, have browner sola and are on higher topographic positions.
* have fragic properties in the lower part of the solum.

Hydric soil
* are generally organic soils, but sandy and mineral soils can also be hydric.
* have a spherical soil component surrounded by air spaces occupied by water.

Irongold soil
* are on fan remnants.
* lack argillic horizon and have carbonatic mineralogy.

Lamont soil
* are more acid and are coarser textured in the lower C horizon.
* range from medium acid to strongly acid in the most acid part.

Lebeau soil
* are slightly acid to moderately alkaline throughout the solum.
* have upper sola that are more acid, and have a grayer matrix.

Light soil
* absorb water faster but dry out quicker.
* are suitable for early crops, whereas heavier soils are preferred for later crops.

Loess soil
* are loose and silty, piled high by wind erosion
  - usually well drained
* fine-grained, wind blown sediment.

Loose soil
* allows water to infiltrate to the plant roots rather than runoff.
* is important so that the pegs can penetrate the soil easily.
* promotes better drainage and makes it easier for the roots to spread.

Loughboro soil
* are on nearly level areas at the base of the mountains.
* have colors of lower chroma and a clayey subsoil and are on nearly level uplands.

Ludlow soil
* are nearly level to strongly sloping and are on till plains, hills, and drumlins.
* have a seasonal high water table.

Marlow soil
* are nearly level to very steep soils on drumlins and uplands.
* have a dense substratum.
