Distinct zones of morphological properties (texture, pedality, colour, coarse fragment content) can be described using the key.
The reason for using only the aspect of presence and absence of pedality as a grouping criterion was that further details of descriptive soil structural information, such as the degree of soil structural development and the shape and size of soil structural units (i.
Soil water retention properties were calculated for each soil, based on estimates of texture, bulk density, and pedality made from the CSIRO National Soil Profile Database and the pedo-transfer approach.
Despite the reduced flooding frequency by the tides and the restricted entrance of fresh water in the tidal flat (Zack and Roman-Mas 1988), especially compared with mangrove forest soils, both hypersaline tidal flat soils showed weak pedality (Table 1, Fig.
1983) noted that the presence of pedality, particle size composition and the grade of structure were most consistently associated with differences in [psi]([theta]), while field texture and the presence of montmorillonite, vermiculite, iron oxide, and quartz were also associated with form and position of the [psi]([theta]).
Highly developed soil features occur throughout the 3 parna layers, particularly the 2 older ones, such as significant pedality, distinctive cutans on ped faces, Fe-Mn oxide and carbonate nodules.
Compound pedality occurs where large peds separate along natural planes of weakness to form smaller peds, which may again part to smaller peds, and so on to the smallest or primary peds.
