“…The reduced concentration of Ca and Mg in mined soils with longer years of fallow could be due to uptake by the roots of the growing vegetation. Also, acidic soils promote leaching of Mg and Ca [ 65 , 66 ].…”

“…It was observed that the material used for filling the pits were mainly washed tailings. Washing of tailings, however, leads to a substantial loss of physicochemical properties either through leaching to deeper levels or as run off since tailings are loose soil particles [ 65 , 66 ]. OC concentration was lower in the unfilled pits as compared to the filled pits.…”

The quality of soils in rehabilitated small-scale mined sites needs thorough investigation since a lot of changes do occur. The study assessed the impacts of small-scale mining activities on concentration and distribution of soil physicochemical properties and heavy metals. The soil samples were collected from 120 (50 m × 50 m) plots. The concentrations of soil physicochemical properties (Ca, Mg, Na, N, P, K, and OC and EC) varied significantly ( p < 0.05) between unmined and mined soils. However, there were no statistically, significant differences ( p < 0.05) observed in the concentrations of Cd, Hg, Pb, As, and Cu between the unmined and mined soils. Despite the generally poor (33.8%) soil quality in the study area, mining activities further reduced it by 24.2%. Soils from mined sites with unfilled/partially filled pits had higher levels of K, Mg, and Na. As mined sites fallow period increased, concentrations of OC and Cd increased, while Ca, Mg, pH, Cu, Pb, and As and value of EC decreased. The number of years that mined land remained fallow, and whether the pits were filled or unfilled during this period should be factored into the mined land rehabilitation processes.

“…These soils are strongly leached soils with low fertility and are found in inter-tropical regions (oxisols) and humid temperate and tropical areas (ultisols) of the world 5 . Leaching of base cations and quantification of soil acidification under simulated acid rain have already been studied on these highly weathered soils of Northeast region of Thailand 6,7 . The main objective of this paper was to find out the interactions between soil base cations and extractable aluminum and iron at different acidic conditions in oxisol and ultisol treated with acidic solutions.…”

This study focuses on the interactions of aluminum and iron with exchangeable bivalent base cations (Ca 2+ and Mg 2+) at different acidity levels in soils treated with acidic solutions. Acidic (pH 5.0, 4.0, 3.5, 3.0, 2.5, 2.0) and non-acidic (7, control) solutions were applied to the soil columns for 45 days representing average annual rainfall. Soil samples from different depths were analyzed for soil pH (acidity) and target elements (Ca 2+ , Mg 2+ , Al 3+ and Fe 2+). The extractable aluminum and iron increased with a decrease in the concentration of exchangeable calcium and magnesium as the soil pH drops to 5 or low particularly in the upper layers of the investigated soils. The concentrations of soluble base cations increased as soil pH became moderately acidic and decreased as soil pH became highly acidic. However, concentration of exchangeable base cations decreased at higher levels of acidity due to accelerated transformations of exchangeable forms into soluble ones.
