This dataset represents the soil moisure regimes from SSURGO and STATSTO soil descriptions for soil map units in the state of northern California that lie within the North Pacific Landscape Conservation Cooperative.
"The term 'soil moisture regime' refers to the presence or
absence either of ground water or of water held at a tension of
less than 1500 kPa in the soil or in specific horizons during
periods of the year. Water held at a tension of 1500 kPa or
more is not available to keep most mesophytic plants alive. The
availability of water is also affected by dissolved salts. If a soil
is saturated with water that is too salty to be available to most
plants, it is considered salty rather than dry. Consequently, a
horizon is considered dry when the moisture tension is 1500
kPa or more and is considered moist if water is held at a
tension of less than 1500 kPa but more than zero. A soil may
be continuously moist in some or all horizons either throughout
the year or for some part of the year. It may be either moist in
winter and dry in summer or the reverse. In the Northern
Hemisphere, summer refers to June, July, and August and
winter refers to December, January, and February.
