“…However, the findings from this study diverge from those of most previous studies. C and N act as two key elements of OM, and soil C org and N tot contents can serve as indicators of variations in soil OM contents (Woś et al, 2023). Irrespective of stand age within Chinese fir plantations, soil C org content distribution in aggregates followed a similar pattern to soil N tot (Figure 2).…”

Maintaining soil biological diversity is an effective approach in facilitating Chinese fir plantations' sustainable development. However, dynamic characteristics of soil microbial and nematode communities during Chinese fir planting remain unclear, particularly on the aggregate scales, which are the main sites of soil biological activity. Therefore, the research aims to explore how stand age (3, 9, 17, and 26 years) of Chinese fir plantations affects soil microbial biomass (including bacteria, fungi, and actinomycetes, based on the phospholipid fatty acid method), nematode abundances (including bacterivores, fungivores, plant parasites, and omnivores‐predators, based on the modified Baermann funnel method), and their diversity within aggregates of differing sizes (>2, 2–1, 1–0.25, and <0.25 mm). According to the findings, both aggregate size and stand age were major factors affecting soil microbes and nematodes in Chinese fir plantations. Specifically, soil microbial biomass (mainly bacteria), nematode abundances (except fungivores), and their diversity peaked within large macro‐aggregates (>2 mm), and the ranking order for stand ages was 17 > 9 ≈ 3 > 26 years. As the main fractions of soil aggregates in Chinese fir plantations, large macro‐aggregates had suitable internal environments for soil microbial propagation and nematode growth and mainly accumulated at 17 years, which caused the prosperity of soil microbes and nematodes at this stand age. Moreover, the partial least squares path model demonstrated that the influence of stand age on soil microbes and nematodes was indirect; but rather, the aggregate composition played a direct role in shaping their communities. Therefore, in order to maintain soil biological diversity, large macro‐aggregates should be protected during the growth of Chinese fir, especially at the late stage (from 17 to 26 years). Overall, these results could provide valuable insights into Chinese fir plantations' sustainable development.

“…The input query words used before now give a much broader list of publications, most of which are completely off-topic, compared to the very narrow-focused results we obtained in 2020. When modified slightly and still using similar keywords (coal, soil, recla*), some of the most recent publications from 2023 visible in the WoS database related to the matter mainly originate from China [167][168][169][170][171][172][173], India [174][175][176], and Poland [177][178][179][180], with research coming from China definitely being the most abundant.…”

Open-cast coal mining is one of the most often-debated industries in the world. Due to the significant environmental and health issues it causes, many of these sites have been reclaimed over the years, and many scientific publications and research has followed. In this paper, we have tried to assess the trends in recent research performed on reclaimed coal mining sites (RMS) by analyzing the publications visible on Web of Science (WoS) between 2015 and 2020 and dividing the research into six categories. The results show that there is a trend of rapid increase in research that deals with carbon and its pooling, nutrients, vegetation, and microbiology, and a significant decline in research on RMS soil physical properties, whereas other categories have shown an increasing but relatively steady trend. The application of modern technologies is also discussed. China, the USA, and India are the countries that quantitatively take the lead in coal RMS research, with India slowly overtaking the US in more recent years.

“…In assessing the effects of reclamation, particular attention is paid to the transformation of soil organic matter [37,38]. In the soil, organic matter with the participation of a numerous and diverse group of microorganisms, undergoes transformations and their rate depends on climatic conditions, soil structure, and the degree of environmental pollution.…”

The aim of the research was to determine the reclamation effectiveness of the use of EM against the background of mineral wool and wool used together with sewage sludge or mineral fertilization with nitrogen, phosphorus, potassium (NPK) on soils degraded as a result of sulfur extraction. The effectiveness of reclamation was assessed on the basis of changes in the total organic carbon (TOC) content and the properties of humic compounds. The obtained results showed that the use of effective microorganisms in relation to mineral wool and wool used in combination with sewage sludge or NPK causes significant changes in the content and quality of soil organic matter. The observed decrease in the content of TOC, humins and an increase in the share of carbon of labile fractions and free and loosely bound with silicate-free (R 2 O 3 ) and calcium (Ca) humus forms indicate, that in the soils in which effective microorganisms were used, mineralization processes dominated in the transformation of soil organic matter. The humification process resulted in more durable humic compounds with a higher content of humic acids and humic acids to fulvic acids ratio (C-HA:C-FA). Supplementing commonly used materials in soil reclamation with the introduction of effective microorganisms is a promising technology. Further research is necessary to determine the composition of these biofertilisers and the optimal doses at which they should be used.
