The key uses field morphological properties (texture, pedality, colour, coarse fragment content) to map the spatially diverse materials that strongly affect plant growth and the success of mine pit rehabilitation (Tables 1 and 2).
Distinct zones of morphological properties (texture, pedality, colour, coarse fragment content) can be described using the key.
3]), coarse fragment content (CF, %), and thickness (cm), representing the mass of carbon per area over a specified depth (t/ha of carbon) (Ellert et al.
3) The effect of coarse fragments on the accuracy of the BD collection methods was tested in constructed soils (0-33% coarse fragments by volume).
Soil samples were analysed to determine particle-size distribution (hydrometer method), calcium-carbonate equivalent (HCI treatment or titrimetric method), organic matter content (Walkley-Black method), soil reaction (saturated paste), percentage of coarse fragments (by volume), and bulk density (by cylinder method) (Soil Survey Staff 1996).
Our data indicate that all selected soil properties except coarse fragments are normally distributed.
The presence of this community in more humid climates is due to the higher topographic position of the shell bars and low water retention of the soils with abundance of sand and coarse fragments
All the sub-layers contain a few visible coarse fragments of variable composition.
It also contains a higher amount of coarse fragments.
The coarse fragments were measured and used to correct the bulk density.
There were few coarse fragments at the upper end of this size class included in the small cores.
The red material contained few coarse fragments
of quartz and feldspars and was very uniform in colour and texture (clay loam to light clay) irrespective of its position in the landscape.
