“…This indicates that in similar pedogenetic conditions, time has a positive effect on the evolution of the SOC in reclaimed soils [25]. Several chronosequence studies [19,26,28,35] have shown that SOC constantly accumulates in reclaimed soils over time, which shows great potential for carbon sequestration. The carbon sequestration potential of reclaimed soils depends mainly on the biomass they contain and its return to the soil; moreover, the carbon sequestration potential is affected by the mechanism protecting the soil carbon [36].…”

“…Studies indicate that the physical, chemical, and biological indicators for reclaimed mine soils constantly improve over time [11,[25][26][27]. For instance, the study of Kumar et al [28] found that the MBC and CO 2 flux of the soil in the Raniganj Coalfield in eastern India approached the levels of natural forest land 21 years after vegetation reconstruction. Mukhopadhyay et al [29] reported that the MBC and CO 2 flux of the soil in the North Karanpura area of India exceeded the levels of natural forest land after 17 years of reclamation.…”

Soil organic carbon (SOC) plays an essential role in the early stages of pedogenisis and ecological restoration in reclaimed mine soils. Dynamic changes in the SOC content are essential for assessing the quality of reclaimed mine soils and the effect of ecological restoration. To objectively assess the carbon dynamics of reclaimed soils, we selected the surface (0-20 cm) soil of farmland under agricultural use (soybean-wheat rotation) from a reclamation chronosequence (R4: 4 years of reclamation, R7: 7 years of reclamation, R10: 10 years of reclamation and R13: 13 years of reclamation) in the Dongtan Mining Area, Shandong Province, China. The adjacent normal, unaffected farmland was used as a control (CK). The results showed that the SOC content gradually increased with the reclamation age until it reached 7.98 g·kg −1 for R13, which accounted for 76% of that of the CK. However, the total carbon contents of the reclaimed soils did not significantly differ from and even appeared higher than that of the CK. This is mainly because the inorganic carbon contents of the reclaimed soils ranged from 2.98 to 12.61 g·kg −1 , all of which were significantly higher than the 0.87 g·kg −1 obtained for the CK. The microbial biomass carbon (MBC) content and the microbial quotient significantly increased with the reclamation age of the soil, and both parameters were markedly higher for R13 than for the CK. The dissolved organic carbon (DOC) content and its ratio to the SOC were significantly higher for R4-R13 than for the CK and DOC/SOC gradually decreased with the reclamation age. Both the reclamation age and the temperature had positive effects on the soil basal respiration (SBR). The SBR rate constantly increased with the reclamation age and was markedly higher at 25 • C than at 15 • C. The temperature sensitivity (Q 10 ) of the SBR showed a clearly decreasing trend for the reclamation chronosequence, but its value remained higher for R13 than for the CK (2.37). The metabolic quotient constantly decreased with the reclamation age, which suggests that the survival pressure imposed on soil microbes by the soil environment gradually decreased. These results indicate that it takes a long time for organic carbon to accumulate in reclaimed mine soil and that rational agricultural use contributes to sustained improvement of the quality of reclaimed soil.

“…A Lyukó és Pereces-patak vízgyűjtőjén a bányászati tevékenységgel érintett, azaz a lefejtett, vagy meddővel borított felszíneken ezen talajok kiterjedése eléri a 20 km 2 -t (SÜTŐ et al, 2014). Bár ezekben a talajokban igen gyors (0,1-4 t•ha -1 •év -1 ) a szerves vegyületek formájában történő szénmegkötés üteme (SHRESTHA & LAL, 2006), de a finomfrakció hiánya, valamint a jelentős térfogatarányú durva törmelék miatt kapcsolata a talaj ásványi részeivel gyenge és labilis (CZIFRA & NOVÁK, 2011;KUMAR et al, 2015).…”

A WRB diagnosztikai elemeit és a felszínborítási adatokat kombinálva a talajokat ért antropogén hatás mértéke szerint négy csoportot alkottunk: 1. nincs talaj, 2. antropogén eredetű talaj, 3. természetes talaj, de lényeges antropogén bélyegekkel, illetve 4. természetes talaj. A négy csoport valamelyikéhez egyértelműen hozzárendelhető a felszínborítási osztályok mindegyike. Az általunk kidolgozott módszer segítségével értékeltük Magyarország talajtakarójának természetességét. Az ország területének 2%-án nem számolhatunk a FAO által definiált értelemben talaj létével, 6%-án antropogén talajok várhatók (Anthrosol, vagy Technosol), 66%-án a természetes talajok antropogén átalakítottsága eléri a WRB diagnosztikai határértékeit, és mindössze 26% azon talajok aránya, amelyekben antropogén hatások a diagnosztikában nem jelennek meg, azaz természetes vagy természetközeli állapotúként értékelhetők. Talajtípusok tekintetében legnagyobb mértékű emberi hatással a csernozjomok, réti és öntés talajok esetében számolhatunk, míg természetközeli állapotú talajok legnagyobb kiterjedésben a kőzethatású és váztalajokon maradtak fenn. A területi különbségek is jelentősek: míg legnagyobb arányban a Hajdúságon és a Körös-Maros közén találunk antropogén hatásokkal érintett talajokat, addig a természetközeli állapotú talajok aránya az Északi-középhegység egyes hegyvidéki területein a legnagyobb. Módszerünk csak becslésre alkalmas, mégis jó áttekintést ad a hazai talajok antropogén átalakítottságának mértékéről, az emberi tevékenység, mint hatodik talajképző tényező jelentőségéről, intenzitásának térbeli eloszlásáról, amely a hazai talajtani adottságoknak egy eddig kevéssé vizsgált aspektusa.

“…Corrected bulk density was found 1.12 g cc -1 (corrected by subtracting courser fraction for soil), which is lower than reference site. Higher values of bulk densities (1.67 g cc -1 ) in reclaimed dumps were reported, which is caused due to compaction and lack of organic matter (Barnshiel and Hower 1997;Maiti 2007;Kumar et al 2015). New mine soils had a slightly higher bulk density than the native soils due to the differences in mining method rather than pedogenic processes.…”

Reclaimed mined lands provide an excellent opportunity to sequester carbon and combat global warming. Carbon sequestration on reclaimed sites depend on age of reclamation, composition of species, geomining conditions (soil characteristics) and prevailing climate. The aims of the present study were to calculate carbon (C)-stock of biomass of 4 years old plantation (dominated by Albizia lebbeck, Dalbergia sissoo and Bambusa arundinacea), understorey vegetation and litter, soil organic carbon in reclaimed minesoil (RMS) and compare with reference forest site. Allometric equation was used for the estimation of biomass C stock and found 13.0 Mg C ha -1 (A lebbeck 7.8 Mg C ha -1 , D sissoo 3.5 Mg C ha -1 and B. arundincea 1.2 Mg C ha -1 ), while stock of understorey vegetation was 0.98 Mg C ha -1 . In RMS, C stock was 16.3 Mg C ha -1 , out of which inorganic C contributed 1.7 g kg -1 (8 % of total soil C), Coal C 8.7 g kg -1(43 % of total soil C) and biogenic C 9.8 g kg -1 (49 % of total soil C). Total C stock in reclaimed site was calculated as 30.3 Mg C ha -1 (equivalent to 111 Mg CO 2 ha -1 ). The study concluded that (i) coal C is responsible for overestimation of C stock in RMS (ii) Maximun C stock stored in aboveground biomass component and (iii) reclaimed mined lands will take approximately 17 years to reach the level of C stock of reference forest site in dry tropical climate.
