Soil environment parameters
The dominant soil of a land resource inventory area is mapped according to the following key soil physical attributes: flood return interval and soil temperature regime (0.3 m depth).
Flood return interval
The classes are described more fully in Webb and Wilson (1995). Frequency of flooding is important for most land activites.
Soil temperature regime
Soil temperature (ºC)at 0.3 m depth. Soil temperature affects crop suitability and yield. The classes used originate from and are described more fully in Webb and Wilson (1995), which in turn is based on the work of Aldridge (1982, 1984) and Aldridge and Cook (1983).
