“…The results of SSI also indicated that the implementation of phytomanagement near tailings with severe soil erosion can stop soil degradation and improve soil structural stability. Revegetation as an effective phytomanagement measure has been shown to improve soil physical properties and anti-erodibility in vulnerable ecological mining regions (Alvarez-Rogel et al 2021; Yuan et al 2022;Zhang et al 2015). We also found that forests were more effective than natural grasslands in improving the water stability of soil aggregates, possibly due to the fact that tree plantings produce more WSA than herbs and shrubs.…”

Aims Revegetation is an effective measure to improve soil structure and nutrients in erosion-prone areas. However, little is known about the impact of diverse phytomanagement of revegetation on soil quality and ecological security near tailings.Methods We investigated the water-stability and soil aggregate nutrients and assessed the associated risk of heavy metal contamination under multiple phytomanagement (natural grassland, artificial forest, and artificial forest mixed with shrubs and herbs) near abandoned tailings on the Loess Plateau, comparing with the adjacent bare land.Results The results showed that phytomanagement significantly enhanced soil aggregate stability, as demonstrated by the rise in soil macro-aggregate proportion (> 0.25 mm, 10.5–22.4%) and geometric mean diameter (16.3–44.0%). Furthermore, the soil organic carbon content (SOC), glomalin-related soil protein (GRSP), aromatic-C, and alkene-C in macro-aggregates increased alongside aggregate stability enhancement. The increased stability of soil aggregates following phytomanagement could reduce the risk of heavy metal leaching, but the increased concentration of heavy metals in the aggregates. In addition, the management of artificial forests mixed with shrubs and herbs greatly reduced the ecological risk of heavy metal pollution compared to other phytomanagement. SOC and GRSP were identified as key factors influencing the risk of heavy metal contamination in soil aggregates following phytomanagement.Conclusion Our study highlights that revegetation of tailings improves soil quality and ecological security by increasing the stability of soil structure as well as SOC and GRSP within the aggregates. Artificial forests mixed with shrubs and herbs could be an optimal phytomanagement to achieve environmental sustainability in tailings areas.

“…Carbon sequestration in a soil is strictly and positively related to vegetation biomass (Yuan et al 2022 ). The found in our study increase in stocks of SOM and of particular elements is typical for the development of young forest stands, and is caused mainly by the increasing with stand age alimentation of tree litterfall to a topsoil (Grüneberg et al 2014 ; Jasińska et al 2019 ).…”

Due to the ongoing climate changes, temperate forests are increasingly exposed to fires. However, until now the functioning of post-fire temperate forest ecosystems with regard to used forest management method has been weakly recognized. Here, we examined three variants of forest restoration after fire (two variants of natural regeneration with no soil preparation—NR, and artificial restoration by planting following soil preparation—AR) regarding their environmental consequences in development of post-fire Scots pine (Pinus sylvestris) ecosystem. The study was conducted using a 15-year timespan in a long-term research site located in the Cierpiszewo area (N Poland) being one of the biggest post-fire grounds in European temperate forests in last decades. We focused on soil and microclimatic variables as well as on growth dynamics of post-fire pines generation. We found that the restoration rates of soil organic matter, carbon and most studied nutritional elements stocks were higher in NR plots than in AR. This could be primarily linked to the higher (p < 0.05) density of pines in naturally regenerated plots, and the subsequent faster organic horizon reconstruction after fire. The difference in tree density also involved regular differences in air and soil temperature among plots: consistently higher in AR than in both NR plots. In turn, lower water uptake by trees in AR implied that soil moisture was constantly the highest in this plot. Our study delivers strong arguments to pay more attention to restore post-fire forest areas with the use of natural regeneration with no soil preparation.

“…A set of restoration actions, such as revegetation, provides positive feedback on soil organic carbon accumulation and soil aggregation (Han et al, 2023; Tang et al, 2010); soil nutrients including carbon, nitrogen, and phosphorus (Bai et al, 2014; Hu et al, 2021; Song et al, 2022; Yuan et al, 2019); soil hydraulic conductivity (Ren et al, 2016); and soil moisture (Li et al, 2018). Different vegetation types used in rehabilitation influence the soil moisture and organic carbon (Gao et al, 2018; Mei et al, 2018; Yuan et al, 2022), saturated hydraulic conductivity, and soil water retention curves (Wu et al, 2023). The diversity of the aboveground communities was strongly and positively correlated with the variety of soil bacteria and eukaryotes (Delgado‐Baquerizo et al, 2018).…”

Mineral mining often results in changes to the soil environment, reducing the sustainability of the surrounding environment. Restoring the physical and chemical properties of soil in post‐tin‐mining areas on the tropical island of Belitung, Indonesia, has been a laborious process after more than 10 decades of land reclamation. We aimed to determine which parameter of the soil properties was responsible for the slow recovery process and if there were other properties that indicated more rapid changes. We measured the physical, chemical, and biological properties of soils of different periods in the post‐tin‐mining areas. We sampled soil from three areas: 0, 1, and 6 years after mining and an adjacent natural forest as a reference site. The soil water content, hydraulic conductivity, bulk density, particle distribution, mineral content, and soil microbial composition were measured in the field and analyzed in the laboratory. The soil showed a fine particle loss and despite the absence of clay, water‐holding capacity was significantly increased in the 6‐year‐old soil. Organic carbon increased by 0.2% after 6 years of reclamation. Copper, iron, manganese, and zinc in the soils fluctuated less. Minimal amounts of Pb and Cd were found. Soil bacterial communities shift with land age. Actinobacteria were dominant a few years after mining, while Proteobacteria colonized the mined area after 6 years. This study examined the more profound changes in the soil properties of tropical post‐tin‐mined land. Soil and bacterial characteristics can be used as markers to monitor the progress of land rehabilitation.
