“…Although storage in stockpiles can have a pronounced effect on many biochemical properties (Abdul-Kareem and McRae, 1984Harris and Birch, 1987Harris et al ., 1989Ross and Cairns, 1981isser et al ., 1984Williamson and Johnson, 1990Johnson et al ., 1991, the period of 2-3 weeks used here was relatively short and unlikely to have had any ma or effects.

The recovery of soil biochemical properties under grazed, grass-clover pasture, after simulated lignite mining, was studied over a 5-year period in a mesic Typic Dystrochrept soil at Waimumu, Southland, New Zealand. The restoration procedures involved four replacement treatments, after A, B, and C horizon materials had been separately removed, from all except the control, and stockpiled for 2-3 weeks . In each replacement treatment, the effects of ripping to 1 .8 m depth, mole drainage, and the use of fertilizer nitrogen were also investigated .Replacement treatment markedly influenced the recovery of herbage production and soil organic C and total N contents, N mineralization, microbial biomass (as indicated by mineral-N flush) and invertase and sulphatase activities . The effectiveness of replacement treatments decreased in the order : 1 . control (no stripping or replacement) . 2 . A, B, and C horizon materials replaced in the same order . 3. A, B, and C horizon materials each mixed with an equal amount of siltstone overburden and replaced in order, 4 . A and B horizon materials mixed before replacing over C horizon material.Ripping increased herbage production, net N mineralization, and to some extent microbial biomass . Drainage had little, if any, effect .Fertilizer N also stimulated herbage production, but depressed clover growth . Over 2 .5 years, it had little detectable effect on the soil properties .Increases in soil invertase and, to a lesser extent, sulphatase activity during the trial were closely related to changes in herbage production . Microbial biomass increased more rapidly than did soil organic C in the early stages of the trial .Rates of net N mineralization strongly suggest that N availability would have limited pasture growth, especially in the treatments with mixed soil materials .

“…We hypothesize the reason for a lack of recovery of the soil microbial biomass is related to the soil structural changes resulting from disturbance associated with surface coal mining. Initial removal of topsoil from a site, placement in stockpiles and subsequent replacement, cultivation and revegetation management practices are known to result important physical changes to affected soils (Severson and Gough, 1983;Harris et al, 1989), including increased bulk density. Further, we believe loss of soil macroaggregate structure by this disturbance may represent an important change in soil environmental conditions, which adversely affects soil biota.…”

Abstract. The potential to sequester carbon and increase organic nutrient storage in disturbed soils, such as those reclaimed after surface coal mining, appears to be significant. Quantification of organic carbon accumulation is complicated, however, by the presence of coal and coal dust in these soils. Our preliminary data on organic matter content of reclaimed soils at surface coal mines in Wyoming suggest they are sequestering carbon at a rapid rate. Data from a surface mine reclamation site near Hanna, WY indicate that surface (0-15 cm)

“…Stockpiling of soil mounds during mineral extraction has been shown to affect the chemical and physical properties of the soil [23,24]. Plant parameters measured from plants grown on soils from Stockpile 1 (age 10 years) produced higher mean values compared with those planted on Stockpile 2 (age 20 years).…”

The Impact of the Quality of Coal Mine Stockpile Soils on Sustainable Vegetation Growth and Productivity

Stockpiled soils are excavated from the ground during mining activities, and piled on the surface of the soil for rehabilitation purposes. These soils are often characterized by low organic matter (SOM) content, low fertility, and poor physical, chemical, and biological properties, limiting their capability for sustainable vegetation growth. The aim of the study was to evaluate the impact of stockpile soils of differing depth and quality on vegetation growth and productivity. Soils were collected at three different depths (surface, mid, and deep) as well as mixed (equal proportion of surface, mid and deep) from two stockpiles (named Stockpile 1: aged 10 and Stockpile 2: 20 years) at the coal mine near Witbank in the Mpumalanga province of South Africa. Soils were amended with different organic and inorganic fertilizer. A 2ˆ4ˆ5 factorial experiment in a completely randomized blocked design with four replications was established under greenhouse conditions. A grass species (Digiteria eriantha) was planted in the pots with unamended and amended soils under greenhouse conditions at 26-28˝C during the day and 16.5-18.5˝C at night. Mean values of plant height, plant cover, total fresh biomass (roots, stems and leaves), and total dry biomass were found to be higher in Stockpile 1 than in Stockpile 2 soils. Plants grown on soils with no amendments had lower mean values for major plant parameters studied. Soil amended with poultry manure and lime was found to have higher growth rate compared with soils with other soil amendments. Mixed soils had better vegetation growth than soil from other depths. Stockpiled soils in the study area cannot support vegetation growth without being amended, as evidenced by low grass growth and productivity in this study.
