“…The pH results of the soil under forest justify the higher levels of exchangeable aluminum obtained in this area at the depths of 0.05–0.10, 0.10–0.20, and 0.20–0.40 m (Table 5), as also found for natural regeneration and planting. Corroborating with the results of the current study, Ribeiro et al (2021) also found lower pH values and high values of Al +3 and aluminum saturation (m%) in soils under different treatments of topsoil submitted to trees planting for recovery of a kaolin mining area. The management practices carried out in the planting area may have significantly reduced the living plant biomass present on the soil surface, which is evidenced by the lower nutrient and organic matter levels in this area compared to the natural regeneration area.…”

Corroborating with the results of the current study, Ribeiro et al (2021) to the deposition of residues that contributed to the increase in soil organic matter levels, especially in constructed topsoil under restoration process after mining (Filcheva et al, 2021;Kalamandeen et al, 2020). There was similar behavior between CECpH7 and SOM values, which were generally significantly higher in FOR than in TPL and NRV.…”

The availability and retention of phosphorus (P) in soils under recovery process after mining operations play an important role in the management of this nutrient. The objective of this study was to evaluate the P adsorption in a reconstituted soil as a function of two forest recovery processes after bauxite mining. We evaluated three systems: native forest (FOR), planting of forest seedlings after bauxite mining (TPL), and natural regeneration of vegetation after bauxite mining (NRV). In each system, eight sampling plots were deployed. In each plot, we collected litter and soil samples. The soil samples were collected at depths of 0–5, 5–10, 10–20, and 20–40 cm, for soil chemical analysis and adjustment of P adsorption isotherms. We also performed an inventory of the tree vegetation to obtain basal area (G) and species diversity (H′). Forest was significantly superior with respect to most soil fertility, litter, and vegetation attributes, followed by natural regeneration and planting. In general, the adsorption curves and maximum phosphorus adsorption capacity (MPAC) in soil followed the order planting > natural regeneration > forest. We observed a negative relationship between phosphorus adsorption and soil organic matter, potential acidity, and available phosphorus. This result highlights the importance of biomass conservation and maintenance to ensure phosphorus availability in reclamation practices. Furthermore, such results indicate that both soil cover and plant species diversity should be considered when selecting species to improve P availability for reclamation of mined areas.

“…Assessing soil indicators and analyzing them only individually in the restoration of tropical forests has been common in the Brazilian tropics (e.g., Rocha et al, 2015;Koryś et al, 2021;Cabreira et al, 2021;Ribeiro et al, 2021), which is risky because it often leads to unclear conclusions, not aligned with a holistic soil health assessment. Therefore, we integrated our dataset into SHI scores based on soil multifunctionality, evidencing the stage of soil health recovery under forest restoration.…”

“…The vegetation removal and the stripping, excavation, and transportation of the soil have different effects on soil physical, chemical, and biological properties [ 8 ]. Rebuild the soil after a degradation process is an essential factor for a successful restoration process [ 9 ]. Several techniques have been used to restore and control soil losses and water runoffs, such as revegetation, which helps in recovering organic matter, restructuring the degraded soil [ 10 ], and the use of organic soil amendments to boost plant performance and soil functions [ 11 ].…”

Biomass residues improve soil chemical and biological properties reestablishing native species in an exposed subsoil in Brazilian Cerrado

Revegetation of exposed sub-soil, while a desirable strategy in the recovery processes, often fails due to extreme soil chemical properties, such as low organic matter and pH levels inhospitable to biological activities such as nutrients cycling and plant establishment. This is the case for approximately 800 ha of the Cerrado biome in Brazil, where erecting the embankment of a hydroelectric dam in the 1960’s stripped vegetation, soil, and subsoil layers thereby distorting the soil properties. This work evaluates the effectiveness of restoration management (RM) treatments, to restore the soil quality, including biological activity and chemical attributes. In a factorial scheme, RM treatments include the addition of organic residue from aquatic macrophytes (AM) at 3 rates (0, 16 and 32 t ha-1), combined with ash from sugar cane bagasse of agroindustrial origin (BA) at 4 rates (0, 15, 30 and 45 t ha-1). RM samples contrasted samples collected from undisturbed Cerrado (CER) as well as a degraded area without intervention (DAWI). The mechanized RM plots received amendments and reforestation of 10 Cerrado native tree species. After 5 years, vegetation covered up to 60% of the surface in RM treatments receiving AM32 + BA45. AM and BA residues promoted height increases in the introduced plants. All RM treatments promoted lower levels of Al3+ than DAWI and CER. The combination of AM32 over the rates of incorporated ash increased soil pH and K values similarly to CER. Microbial-related variables, such as microbial biomass-C was the largest in CER, followed by the RM treatments, and the lowest in DAWI. The microbial quotient was no different between CER and RM treatments. The addition of residues such as AM and BA increased the vegetation covered, improved chemical and microbiological indicators. Thus, the residues used aided the recovery process of intensely degraded soils in the Cerrado area.
