Redefinition of new Rooting Depth classes

Current situation

The rooting depth in CGMS was first based on rules described by van Dam et al. (1994) and later updated by van Diepen (1997). Around 1998 rooting depth was updated again using pedotransfer rules described by King et al. (1995) and based on the three attributes:

• FAO soil name,
• parent material and
• phase.

Table 6-1 shows the different rooting depth classes used in CGMS.
