Summary: Soil stoichiometry is an important indicator for assessing soil C, N, P stocks balance and ecosystem stability. This study investigated the soil organic C, N, P stocks and stoichiometry along a vegetation succession gradient in a reclaimed post-mining area. The results showed that revegetation type significantly influenced soil C, N stocks and stoichiometry through litter and fine root inputs. Shrub restoration with diverse species was found to be the most efficient plant type in rebuilding soil C and N stocks and promoting restoration process of degraded lands.

Summary: Changes in land use can influence soil biodiversity and the ecological interactions of soil microbes and their predators. This study found that different land use types affected the composition of diazotrophs and shaped the occurrence of specific indicator diazotroph taxa. Conversion of cropland to grassland increased the complexity of diazotroph and bacterivore networks. Different bacterivores had varying effects on diazotroph community structure. Land use could control diazotroph community composition by altering soil properties and regulating abundance of bacterivores.

Summary: This study investigates the effects of freeze-thaw cycles (FTCs) on soil organic carbon (SOC) distribution in a watershed in northeast China. The results show that SOC decreased in a significant portion of the watershed after FTCs, with spatial autocorrelation decreasing in certain soil depths. SOC was found to increase in certain areas depending on topography and land use types. The study also explores the factors influencing SOC change and provides equations for predicting SOC distribution after FTCs.

Summary: The study found that soil organic carbon (C) and nitrogen (N) had similar spatial patterns, while sulfur (S) distribution in soil was different. There was no correlation between soil S and C. The constant C:N ratio in soil was attributed to soil biological processes, while soil C:S ratio fluctuated due to geochemical processes and exogenous S inputs.

Summary: The spatial distribution of soil organic carbon (SOC) is influenced by natural environment and human activities. This study in a vineyard region in Serbia found that land use is a crucial factor controlling SOC content, with vineyards having lower SOC than forests. Soil management practices, such as deep tillage and organic amendments, were shown to preserve SOC in subsoil and prevent carbon loss from surface layers, reducing soil compaction and erosion risk.

Summary: Environmental degradation and carbon emissions are major global concerns, leading policymakers to consider strategic measures to increase carbon sequestration capacity and mitigate climate change effects. Soil organic carbon (SOC) provides a reliable mechanism to ameliorate climate change, but climate change and land-use transformations threaten current mitigation approaches. This study models the effects of simulated climate and land-cover change on SOC inventories in South Africa until 2050, showing a decline in SOC stocks and forest coverage, which have important implications for policymakers, land use managers, and climate change experts in assessing the feasibility of existing SOC management protocols and land-use planning agenda.

Summary: This study investigated the effects of silicon on maize seed germination and seedling growth, finding that a concentration of 15 g.L-1 significantly stimulated seed germination and promoted seedling growth. Silicon treatment also increased chlorophyll content, osmotic material accumulation, and antioxidant defense system activity, while reducing membrane system damage, reactive oxygen species contents, and stomatal aperture. These results suggest that silicon can enhance maize growth and yield, providing a solid foundation for future crop production.

Summary: The study found that the spatial autocorrelation of AN varied across different soil depths, with moderate levels in 0-20 cm and 20-30 cm depths, and a strong level in 40-50 cm depths. AN distribution differed across different aspects and slopes, and the slope steepness of 6-8% was identified as a key point influencing AN dynamics. The management of forestland and areas with high AN content can play a crucial role in reducing N loss and ensuring sustainable crop yield.

Summary: In this study, the degradation process of microplastics (MPs) in soil was investigated in relation to crop growth and straw amendment (SA). The results showed that both crop growth and SA influenced the morphology, functional groups, total mass, and abundance ratio of different-sized MPs. Maize and soybean growth, with and without SA, accelerated the change of MPs in the soil.

Summary: This study reviewed the effect of natural vegetation restoration (NVR) on microbial community and their ecological functions in gullies of mollisols. The results showed that NVR improved microbial diversity and complexity in gullies, and promoted bacterial community composition similarity between gullies and deposition areas. Soil organic matter regulated microbial diversity by balancing soil available phosphorus, soil moisture, and pH, which stimulated key bacterial biomarkers and enriched bacterial functionality in gullies. Abundant dicotyledons regulated fungal community composition and increased fungal richness in the soil depth of 0-20 cm.

Summary: Plastics production is increasing while their recycling rate is lower, leading to a large amount of microplastics accumulating in the environment. The migration, distribution, and adverse effects of microplastics in terrestrial and aquatic environments are still not fully understood. This review summarizes the migration and distribution of microplastics based on the newest publications and highlights the transfer in biota and their biological effects. The review aims to help reevaluate the uncertain behaviors of microplastics and fully understand their biological effects in different environmental conditions.

Summary: Soil quality plays a critical role in sustainable agricultural development, especially in regions with thin-layer black-soil coverage that have experienced severe degradation. This study constructed an integrated soil quality index (SQI) using diverse datasets and found that soil degradation was observed in a typical thin-layer black-soil region in China. Black-soil thickness, soil organic matter, and total nitrogen content were strongly correlated with corn yield. The minimum-dataset-based SQI using six soil properties within 0-30 cm was the optimal solution for SQ evaluation. Improving soil quality and managing surface black soil loss are crucial for increasing crop yield in these regions.

Summary: This study analyzed the nitrate nitrogen removal characteristics of Pseudomonas JI-2 under strong alkaline conditions, as well as the composition and functional groups of extracellular polymeric substance. Non-targeted metabonomics and bioinformatics technology were used to investigate the alkaline tolerance mechanism. The results showed that JI-2 has strong alkaline tolerance and can remove nitrate efficiently even under alkaline conditions. It secretes poly-saccharides, acidic functional groups, and compatible solutes, and regulates key metabolic processes to adapt to the strong alkaline environment.

Summary: This article introduces a simple, cost-saving and high efficient method for the extraction and separation of microplastics from soil with high organic matter content. The study used different flotation and digestion solutions to extract microplastics and digest organic matter from the soil. The results showed that the best flotation solution was ZnCl2 with recovery rates ranging from 96.1% to 99.0%, and the best digestion method was H2SO4:H2O2 with a digestion rate of 89.3%. These findings were validated by known concentrations of microplastics and were successfully applied to extract microplastics from vegetable fields in Northeast China.

Summary: This study examined the effects of different biochar application methods on soil quality, crop yield, and agronomic characteristics in moderately degraded Mollisols. The results showed that the same biochar application method had different effects on crop yield at different application rates, while the homogeneous biochar application method had a more significant effect on improving soil quality. The impact of the heterogeneous biochar application method gradually increased over time.
