“…Available forms of K (K AAE , K CO2 and K W ) varied considerably across the canton and presented a coefficient of variation (CV) higher than 50%. Such variability has already been reported at field and/or region scales (Lauzon et al, 2005;Wilding and Drees, 1983), with an increased variability at larger scales (Wilding and Drees, 1983). The correlation between K CO2 and K W (Fig.…”

“…Descriptive statistics (minimum, maximum, mean, and coefficient of variation [CV]) for each cycle are summarized in (Wilding and Drees 1983;Nielsen and Bouma 1985). Variations in soil characteristics are often attributed to differences in parent material, pedogenesis, and land use (Shi et al 2008), and moderate variability of SOM reflects low variation in soil type (Fig.…”

“…A classification scheme identifies the extent of variability for soil properties based on their coefficient of variation [32]. Consequently, CV values of <0% -15%, 16% -35% and >36% indicate little, moderate, and high variability, or Classes I, II and III soils, respectively.…”

“…Consequently, CV values of <0% -15%, 16% -35% and >36% indicate little, moderate, and high variability, or Classes I, II and III soils, respectively. On the basis of this classification scheme [32], the variability in bulk density values for the soils can be described as showed the greatest variability in aggregate stability due to absence of vegetation. Large variability in soil properties was noted for the degraded forest soils elsewhere in the humid tropics [33].…”

Land degradation caused by surface mining of gold has been extensive in Ghana. In recent years rehabilitation of some degraded lands by re-vegetation has been undertaken. This study provides quantitative data on the quality of some rehabilitated and un-rehabilitated mined soils within the AngloGold-Ashanti gold concession in parts of the semi-deciduous forest zone of Ghana. Soil properties determined included texture, bulk density and aggregate stability, pH, organic carbon, available phosphorus, total nitrogen, cation exchange capacity, exchangeable bases, exchange acidity, Fe, Mn, Ni, Cu, Zn, Cd, and Pb. Aggregate stability as a physical quality indicator revealed that aggregates of the rehabilitated mined soil had become more stable and similar to the control unmined soil due to litter and carbon additions from planted trees. The nutrient levels were very low because of the presence of low activity clays inherent in the native soil. Organic carbon content in the rehabilitated soil had increased above that of the unrehabilitated soil. Variability in soil properties, especially organic carbon and aggregate stability, was minimal in the unmined and rehabilitated soils implying that soils at the two sites were most robust and resistant to crushing and rupture. Quality index of the unmined control soil was 36.5% indicating that the quality of the soil was 63.5% relative to the optimum quality because of inherent poor soil properties. The mined rehabilitated and unrehabilitated soil had index values of 32.5% and 24.4%, respectively. The marginal difference of 4% in soil quality between the control and rehabilitated soil shows that it is possible to maintain the health of soils with inherent physical and biochemical deficiencies if reclamation regulations are adhered to. In this way, the socio-economic dilemma of exploiting natural resources for the benefit of societies is ameliorated while maintaining an ecosystem balance.
