“…Successional establishment of many leguminous herbaceous species on mine spoil in tropical environment can explain such higher N accumulation rate. Dancer et al [59] have suggested that 700kg ha -1 of N accumulation in soil is critical for the establishment of a substantial self-sustaining ecosystem in disturbed lands. Roberts et al [35] and Dancer et al [59] have identified accumulation of nutrients as an important feature of ecosystem development in naturally colonized spoils.…”

A pre-requisite to any revegetation plan, as well as restoration of degraded land is the knowledge of physicochemical characterization, which is crucial for prediction of ecological succession for mine overburden spoil, including soil texture, hydrological regimes, pH, organic carbon, nitrogen and extractable phosphorous. Effects of mining activities are markedly adverse, because many of the beneficial soil characteristics may require a long span of time to develop through pedogenic processes, in order to reach the native forest soil condition, which evaluates the degree of functional microbial processes for ecosystem recovery, and used as an index of the progress of soil genesis in mine overburden spoil. Mine spoil samples collected from six different age series overburdens showed progressive increase in clay (%) (r=0.982, p<0.001), water holding capacity and organic carbon, which indicates the development of soil structural stability, aggregation with the increase in age of overburden spoil. The pH of spoil samples was noted to be in acidic range (6.11-6.87). Approximately, 93.7% variability in clay (%) among different mine spoils can be explained due to the variation in organic carbon. The organic carbon, nitrogen and phosphorous content showed an improvement of 2 mg C/g spoil, 161 µg N/g spoil and 8 µg P/g spoil, respectively, over a period of 10 years. Thus, the net annual accumulation rate for carbon, nitrogen and phosphorous on hectare basis amounted to 255 kg C/ha/yr, 20 kg N/ha/ yr and 1 kg P/ha/yr, respectively. Further, it was estimated that the mine overburden spoil to attain the soil features of nearby native forest soil at study site through the process of reclamation, shall take approximately 28 years.

“…In nutrient poor soils, legumes have been shown to perform well when compared to non-legume species (Elias andChadwick 1979, Imsande andTouraine 1994). Legume growth on sandy soils increases the amount of plant-available nitrogen (NH4 + and NO3 -) up to 250 kg/ ha per year, via nitrogen fixation and leaf decomposition, and in return promotes the establishment and growth of other plant species (Dancer et al 1977, Jefferies et al 1981). Morris and Wood (1989) found that non-leguminous seedlings that established in the presence of Lupinus lepidus exhibited greater growth and flowering probability than in bare patches.…”

This open access article is distributed under the terms of the CC-BY- ABSTRACTSand dunes in the Great Lakes Basin are ecologically and economically important. One economic value of sand dunes is sand mining. However, sand mining activities reduce soil quality which represents an impediment to reclamation efforts. Soil quality improvements followed by revegetation may be necessary for successful reclamation. This study evaluates the germination and initial growth of two legume species, wild lupine (Lupinus perennis) and Illinois bundleflower (Desmanthus illinoensis), and two warm-season grass species, Indian grass (Sorghastrum nutans) and little bluestem (Schizachyrium scoparium), in the presence of three soil amendments (coco peat, municipal sewage sludge, and sphagnum peat moss) added to spoil from a local sand mine. Species were grown in pots and propagated under greenhouse conditions. Our results indicate that lupine and Illinois bundleflower exhibited the greatest germination and growth and are recommended as potential candidates for the reclamation of sand mines. Indian grass and little bluestem exhibited low rates of germination and growth. Among spoil amendments, we recommend coco peat based on germination and root, shoot, and total biomass results. Peat moss also exhibited increased rates of germination and growth. We did not observe any germination success for seeds sown in sewage sludge amended spoil. The lack of germination in the sewage sludge amendment may be due to a combination of unfavorable abiotic and biotic soil conditions such as electrical conductivity, pH, or soil microbial activity. Our results are helpful in determining which species and amendment combinations are useful candidates for revegetating former sand mines or similar habitats.

“…Many mine rehabilitation programmes use legumes for this purpose. Legumes have been shown to improve the nitrogen levels of many mine soils (Dancer et al, 1977a;Dancer et al, 1977b;Jencks et al, 1982;Palaniappan et al, 1979).…”

Nitrogen is often provided to impoverished overburden dumps through the establishment of legumes. Low indigenous soil nutrient levels, summer drought conditions and an acidic mining overburden represent major obstacles to successful rehabilitation of open-cut coal mining at Collie in southwest Western Australia. In this study,Acacia pulchella, a native Western Australian species often used in rehabilitation of mined lands, was shown to nodulate and grow in coal mining overburden with pH values less than 4.0 under glasshouse conditions. Plant growth (both top and root dry weight), nodule fresh weight, and nodulation success was best at a pH near 5.0, a value only slightly lower than the typical soil pH of the native jarrah (Eucalyptus marginata) forest. Acetylene reduction rates were reduced by acidity and ranged from 8.2 μm C2H4g(-1)hr(-1) at pH 6.77 to 3.0 μm C2H4g(-1)hr(-1) at a pH of 3.98. Four additional plant species were found to occur and to nodulate on acid overburden material at Collie.
