“…Rehabilitated mined site is dominated by lantana camara providing soil fertility through leaf foliage in contrast with undisturbed site which had no vegetation beneath the woody vegetation and recently mined site had no vegetation. This result compares favorably with studies done by Emadi et al, 2008;. Various studies have examined the effects of land use on physio-chemical properties of soil (Emadi et al, 2008).…”

The woody vegetation in semi-arid area is important in providing ecosystem services and goods. However, it faces threats manifested in land-use changes such as mining. This study aimed at assessing the composition and diversity of woody vegetation as well as inherent soil physico-chemical parameters in a previously mined area and comparing it with a semi-pristine adjacent area. Six transects containing five plots each were established within two blocks separated by a river. In each plot, data was collected on woody tree growth characteristics and soil parameters. Thirteen woody species were recorded in the rehabilitated mined and twenty two in semi-pristine sites with Ficus sycomorus L Moraceae being the dominant species at the two sites. Woody vegetation diversity was higher in semi-pristine site than in the rehabilitated mined site. However, this was not significant (t-test, =D.F=1 P=0.767). Mean soil nutrients (F 2 , 7 . = P=0.821), pH (F 2 , 7 . =109.88, P=xxx), was higher in rehabilitated mined sites while mean soil temperature (F 2 , 7 . =9.08, P=0.011) was higher in mined areas. Rehabilitating mined sites can bring back species diversity, composition, however what is not clear is whether ecosystem functions are restored.

“…The smaller aggregates in the cropland soils are therefore consistent with the lower SOM content (Emadi et al, 2008). Loss of the larger aggregate sizes in cropland could also be due to tillage rapidly destroying live and decaying plant roots, fungal hyphae, earthworms and termites.…”

“…There were no significant differences in MWD between forest and pasture soils (Emadi et al, 2008) Although the importance of organic matter to improve soil aggregate stability is well known, the experiments showing the beneficial effects of organic matter on aggregate stability have been varied. For instance, some workers (Christensen 1986) found a significant correlation between organic matter and aggregate stability.…”

Addis H., Klik A., Oweis T., Strohmeier S. (2016): Linking selected soil properties to land use and hillslope -A watershed case study in the Ethiopian Highlands. Soil & Water Res., 11: 163−171.Deforestation of native forests for crop production in the Gumara-Maksegnit watershed, located in the Lake Tana basin, Ethiopia, dramatically increases the vulnerability of the soil for rainfall driven erosion. Hence, the central task of the study is to investigate general links of land-use and topography related to selected soil properties. The 53.7 km 2 watershed was divided into a 500 × 500 m square grid to sample bulk density (ρd), pH, soil organic carbon (SOC), total nitrogen (TN), available phosphorus (AP), and texture of topsoil. Such properties were investigated with respect to the two main land-uses, forest and agriculture, and three different slope steepness classes, 0-10%, 10-30%, > 30%. Descriptive statistics and correlation analyses were undertaken to explore potential dependencies of the obtained soil parameters according to land-use and slope steepness. The study indicates higher SOC, TN, silt and sand content in forest soils compared to agricultural soils, while solely ρd is lower in the forest soil. Overall increases of SOC, TN, silt, and sand content from the gentle to the steep slopes have been observed for both land-uses. In contrast, clay content and ρd seem to increase from steep to gentle slopes on agricultural areas, which might be due to accumulation of particularly fine soil particles eroded from the steep areas. Basic correlations valid for all land-uses and slope steepness classes have not been detected. Nevertheless, the study suggests slope steepness as a tool to assess the potential drivers of soil depletion in the Ethiopian Highlands.
