Custom Soil Resource Report
Levee (map symbol)
An embankment that confines or controls water, especially one built along the
banks of a river to prevent overflow onto lowlands.
Linear extensibility
Refers to the change in length of an unconfined clod as moisture content is
decreased from a moist to a dry state. Linear extensibility is used to determine
the shrink-swell potential of soils. It is an expression of the volume change
between the water content of the clod at 1/3- or 1/10-bar tension (33kPa or
10kPa tension) and oven dryness. Volume change is influenced by the amount
and type of clay minerals in the soil. The volume change is the percent change
for the whole soil. If it is expressed as a fraction, the resulting value is COLE,
coefficient of linear extensibility.
Liquid limit
The moisture content at which the soil passes from a plastic to a liquid state.
Loam
Soil material that is 7 to 27 percent clay particles, 28 to 50 percent silt particles,
and less than 52 percent sand particles.
Loess
Material transported and deposited by wind and consisting dominantly of silt-
sized particles.
Low strength
The soil is not strong enough to support loads.
Low-residue crops
Such crops as corn used for silage, peas, beans, and potatoes. Residue from
these crops is not adequate to control erosion until the next crop in the rotation
is established. These crops return little organic matter to the soil.
Marl
An earthy, unconsolidated deposit consisting chiefly of calcium carbonate mixed
with clay in approximately equal proportions; formed primarily under freshwater
Iacustrine conditions but also formed in more saline environments.
Marsh or swamp (map symbol)
A water-saturated, very poorly drained area that is intermittently or permanently
covered by water. Sedges, cattails, and rushes are the dominant vegetation in
marshes, and trees or shrubs are the dominant vegetation in swamps. Not used
in map units where the named soils are poorly drained or very poorly drained.
Mass movement
A generic term for the dislodgment and downslope transport of soil and rock
material as a unit under direct gravitational stress.
