Summary: Free-living nitrogen fixation is an important nitrogen source for the initiation and development of ecosystems on barren lands. Carbon supply plays a crucial role in regulating the process of free-living nitrogen fixation in nitrogen-poor soils, and plants can effectively regulate rhizosphere diazotrophs through root exudates.

Summary: This study used metagenomic sequencing to investigate the carbon cycle in biocrusts. It found that there are assimilation and dissimilation modules in the carbon cycle, and the relationships between these modules change during succession.

Summary: Soils of unmanaged fallow lands differ from soils of conventionally background areas in terms of the preservation of agrohumus horizons, absence of forest litter, and less pronounced podzolic horizon. Agricultural development and removal of soils from agriculture cause significant changes in the composition of soil organic matter. In postagrogenic soils, the increased total carbon content in the upper mineral horizons is mainly attributed to the increase in organic matter firmly bound with the mineral soil matrix.

Summary: Based on the assessment of different types of land, it was found that agricultural overgrowth significantly reduces species richness and biodiversity of plant communities, and the restoration of biodiversity is challenging. To preserve biodiversity, it is recommended to intersperse croplands with sufficiently large uncultivated plots.

Summary: Tailings ponds from mining operations pose serious environmental hazards, and their bioremediation is a topic of ongoing exploration. Primary succession plays a crucial role in establishing and developing biotic communities, with soil carbon and nitrogen cycling being vital. This study investigates the microbial-mediated carbon and nitrogen cycling patterns during primary succession in different types of tailings ponds. The results show that primary succession promotes microbial carbon and nitrogen cycling, improving soil nutrient availability and enzyme activity. The findings support the optimization of bioremediation strategies for tailings ponds.

Summary: Soil enzymatic activity was assessed in two sites at different elevations in the Stelvio Pass area to study the effects of climate change. The study found that subalpine soils had higher microbial activity and certain physicochemical properties compared to alpine soils, while short-term warming effects had less significant impacts on enzymatic activities than vegetation shift caused by warming-induced upwards movement.

Summary: The mounds of Microhodotermes viator in the South African west coast region have the potential to store a substantial amount of organic and inorganic carbon, and they play an important role in the carbon cycle.

Summary: This study aimed to assess the quality of agricultural soils affected by heavy metal accumulation from fertilization and their bioavailability, with consideration of their biological and chemical properties in relation to distance from communication routes. The results showed that enzyme activity in the soils was impacted by heavy metals, and their accumulation was significantly influenced by distance from the road, sampling location, sampling date, and research duration. The highest accumulation of zinc, cadmium, lead, and copper was found at a distance of 5-20 m from the road. The activities of phosphatase and dehydrogenases were identified as the best bioindicators for assessing contamination of roadside soils used for agriculture. Organic fertilizers and crop residues should be incorporated into agroecosystems along roadsides to maintain their activity, which is related to soil organic carbon content.

Summary: In the past, the practice of using formiguers to burn woody plant residues was common in many regions of Spain. This practice resulted in the formation of charcoal and other carbon residues, which increased soil fertility. A micromorphological approach was used to study the relationship between charcoal and biological activity in soils where formiguers were traditionally applied in Catalonia. The study found that the presence of charcoal significantly influenced bioporosity in the studied soils.

Summary: The study found that the soils of the Maritime and sub-Antarctic regions have biological communities that can survive extreme environmental conditions. The soil microbial biomass tended to peak at 67-68 degrees S, coinciding with relative soil organic carbon and total nitrogen abundance, likely due to guano and excreta from sea birds and mammals. Despite having small and relatively inactive microbial communities, these soils efficiently convert organic resources into microbial biomass.

Summary: Understanding the processes guiding microbial community assembly in soils is crucial for predicting microbiome structure and function. Our study found that salt and nitrogen additions reshaped bacterial assembly, constraining alpha diversity and biomass accumulation. In contrast, the source soil origin had little impact on assembly trajectories.

Summary: This study investigated the successive development of microbial communities on environmentally friendly Artificial Biological Reef structures (ABRs). The results showed that Cyanobacteria, Proteobacteria, and Planctomycetota were the most dominant phyla. The healthy microbial films on ABR surfaces enhanced the restoration of macrobenthic community in the damaged coral reefs.

Summary: The depopulation of rural areas in Russia has caused the abandonment of arable lands and subsequent natural reforestation. This study focused on the soils and vegetation of six stages of pine forest restoration in the Smolensk region. The results showed changes in soil composition and macrofauna abundance and biomass as the forests progressed from initial restoration to mature stages.

Summary: The role of soil organic carbon (SOC) sequestration as a 'win-win' solution to both climate change and food insecurity is critically examined in this article. The inclusion of SOC saturation in estimations significantly reduces the potential contribution of SOC sequestration to climate change mitigation, and the observed yield effects of increasing SOC are inconsistent. The article argues for a shift towards soil-smart agriculture that takes into account specific local conditions and quantifies multiple soil functions for land sustainability and food security.
