“…These nontarget species are often promoted by the release of nitrate from the accelerated oxidation of organic matter induced by stockpiling before soil transfer (Bruelheide & Flintrop 2000). The storage and transfer of large quantities of soil therefore have also an impact on its properties, its quality, and the life it supports (Johnson et al 1991;Whalley et al 1995;Curry 2004). Moreover, translocated soil may carry a higher nutrient content due to the disturbance of soil structure (Bruelheide & Flintrop 2000) and compaction that can occur during transfer (Trueman et al 2007).…”

A last resort means to restoring a severely degraded ecosystem can involve soil transfer, especially when destruction of an undegraded system has been previously independently planned. We measured the impact of different soil transfer treatments that varied in vertical and orderly reconstitution of the main soil horizons on the microbial activity and organic matter composition during restoration of a Haplic Cambisol in a steppe ecosystem. There were differences between the topsoil of the reference ecosystem and the soil transfer treatments in terms of physicochemical parameters and microbial activity, but this was not the case when topsoil was not replaced at the soil surface. Three years following restoration, the transferred topsoil treatment, where the three main soil layers were transferred, contained lower particulate organic matter content than the steppe reference soil, despite similarity in potential carbon mineralization. Soil profile descriptions revealed strong differences in overall organization between the transferred soil and the undisturbed steppe soil, particularly with respect to lower biological activity and a lack of connectivity between pedological horizons via the plant root systems and the earthworm activity in the transferred soil. This suggests that soil transfer conducted to retain soil horizons provides good results when the topsoil is transferred, but it may result in altered biological activity, profile morphology, and organic matter content compared with the reference system

“…In reinstated materials with limited nutrients and high rates of leaching, there are likely to be even greater benefits from an association with an ectomycorrhizal partner, which can aid the efficient uptake of nutrients (Marx 1975). However, studies on newly reinstated surface mines suggest that overburden and subsoil materials are initially likely to lack mycorrhizal propagules (Johnson et al 1991; Miller 1993; Malajczuk et al 1994).…”

Lunt, P. H., Hedger, J. N. (2003). Effects of organic enrichment of mine spoil on growth and nutrient uptake in oak seedlings inoculated with selected ectomycorrhizal fungi. ? Restoration Ecology, 11, (2), 125-130. Sponsorship: BBSRC and the Opencast Executive of British CoalPoor growth of Quercus robur L. (oak) trees has been reported on mine sites where overburden and subsoil have been used in the reinstatement of surface layers. This stunting has been attributed to a lack of macronutrients and to an adverse soil environment for root growth and mycorrhizal development. Growth, mineral nutrition, and ectomycorrhizal colonization of Q. robur seedlings were studied in an experiment carried out under controlled growing conditions in which mine spoil material was enriched with a leaf litter mulch. Enrichment of mine spoil material was found to produce a significant increase in growth and foliar N concentrations of oak seedlings. Inoculation with three taxa of ectomycorrhizal fungi did not benefit seedlings when mine spoil was the only substrate, possibly due to the poor physical properties of the unamended spoil and lack of nutrients. Inoculation with two taxa, Laccaria laccata and Hebeloma crustuliniforme, isolated from 3-year-old trees produced a significant stimulation of growth in the organically enriched treatment, which was believed to be due to greater uptake of mineralized N. However, Cortinarius anomalus isolated from fruit bodies associated with a 15-year-old tree did not increase biomass. The presence of organic matter was found to result in a significant stimulation of mycorrhizal infection by both inoculum and contaminant mycobionts. Recommendations are made for improving the establishment and growth of oak seedlings on reinstated sites.Peer reviewe

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 .
