“…Furthermore, the bulk density at the compacted site exceeds the general range of 1.00 g cm −3 to 1.50 g cm −3 reported for uncompacted soils [27], whereas at the uncompacted site values varied around the upper limit. However, bulk density values within soil profile at the compacted site were within the range of 1.63 g cm −3 to 1.74 g cm −3 reported for top 20 cm depth of recently reclaimed postmining soils in the region cultivated to Dactylis glomerata L. [28]. Interestingly, bulk density within soil profile at the uncompacted site was around the range of 1.57 g cm −3 to 1.60 g cm −3 reported by Boldt et al [29] for younger reclaimed site at the study area.…”

The impact of soil compaction on bulk density and root biomass ofQuercus petraeaL. was assessed after 85 years of reclamation of post-lignite mining soil at Welzow-South, in Lusatia, Germany. Bulk density of core soils sampled from 20 to 25 cm, 100 to 105 cm, and 200 to 205 cm depths and oven-dried biomass ofQ. petraearoots sampled from 0 to 30 cm and at successive depths of 20 cm, up to 210 cm depth at compacted and uncompacted sites were determined. Bulk density was significantly higher at 20 to 25 cm (1.74±0.09 g cm−3) and 100 to 105 cm (1.65±0.06 g cm−3) depths of the compacted site. Likewise, compaction induced significant greater root biomass within the 0 to 70 cm depth with higher bulk density; root biomass at this depth was 2-fold greater compared to the uncompacted site. Root biomass decreased with soil depth and showed significant relationship with depth at both sites. The result indicates that, after 85 years of reclamation, the impact of soil compaction persisted as evident in higher bulk density and greater root biomass.

“…Samples were taken from an uncultivated area at successive 5-cm steps up to a depth of 30 cm using 100 cm 3 sample corer as outlined by Rodionov et al (2012). The soilforming substrate had an average bulk density of 1.6 AE 0.1 g/cm (mean AE standard error), an organic carbon content of 0.9 AE 0.5 g/kg, an inorganic carbon content of 3.2 AE 0.8 g/ kg, a total nitrogen content of 0.1 AE 0.0 g/kg and pH (H 2 O; 1:2.5 w/v) of 8.6 AE 0.3 (see Rodionov et al, 2012, for method details).…”

“…In comparison, Qu et al (2008) showed that the use of cross-linked polyacrylates may also result in increased water-holding capacity of the soil, while the degradation of these polymers is not known to generate toxic products. In addition, the reduced bioavailability of toxic trace elements resulting from application of polyacrylates (de Varennes et al, 2006;Qu & de Varennes, 2009) or of polyacrylates mixed with mineral additives (commercial soil additive = CSA) promoted a successful establishment of annual and perennial crops (Rodionov et al, 2012). However, the degradation rate of cross-linked polyacrylates in soils remains unclear.…”

Application of hydrophilic polymers composed of cross‐linked polyacrylate can improve soil water‐holding capacity and accelerate the restoration of post‐mining substrates. In this work, we studied the persistence of a polyacrylate polymer incorporated into a soil and its impact on plant nutrients at a reclamation site of former lignite mining in Lusatia (Germany). In contrast to autumn application, the incorporation of the polymer enhanced the sequestration of plant‐derived carbon in the soil, which was reflected by a significant increase in the concentration of a lignin marker. Attenuated total reflexion–Fourier transform infrared spectra (ATR‐FTIR) and total elemental contents in the applied polymer suggested an intensive cation exchange between the polymer framework and the soil‐forming substrate. In addition, there was an enrichment of carbonaceous material, which seems to reduce the swelling and thus the water‐holding capacity of the cross‐linked polyacrylate. Conversely, this process protected the polymer structure from rapid decomposition.
