The tread + dung treatment accounted for ~50% of TP losses for the Brown soil, followed by 45, 65, and 45% of TP losses for the Melanic, Pallic, and Recent Gley soils, respectively.
Figure 3a illustrates that while the Pallic and Brown soils appeared to be more affected by aggregation, especially within the light sample, only the Pallic soil was significantly different, and only for the light sample compared with the Melanic soil.

The ASC successfully recognises characteristics of near surface horizons with reference to Peaty, Humose, Melacic, or Melanic Subgroups available to most Orders.
Few (Fitzpatrick and Le Roux 1977) basic studies have been conducted on the clay mineral association in melanic horizons in South Africa.
As far as mineralogy is concerned, however, virtually no basic studies have been conducted on the phyllosilicate associations of melanic horizons in South Africa.
Evaluation of the above data (Van der Merwe 2000) showed that melanic soils in South Africa cover an area of about 2.
The melanic A horizons investigated in the present study contained one or more of the clay minerals, viz.
Melanic soils, per definition, must exhibit a dark colour, a relatively high base status and a blocky structure (MacVicar et al.
For this reason the clay mineral associations in the melanic horizon have been grouped on the basis of their layer charge characteristics (Fig.
No less than 24 (>40%) of the melanic horizons were devoid of mica and HIV, the vast majority of them being dominated by smectite and vermiculites.
