Summary: This study conducted a seven-year warming experiment in a coastal wetland in the Yellow River Delta and found that climate warming led to a decrease in soil organic carbon content, especially in the topsoil. Additionally, warming reduced the content of labile organic carbon, including dissolved organic carbon and particulate organic carbon, through increased soil salinity. However, it did not affect the content of recalcitrant mineral-associated organic carbon. The findings highlight the importance of considering the varying responses of different soil organic carbon fractions to warming for accurate projections of soil organic carbon dynamics in coastal wetlands under future climate change.

Summary: This study aims to explore the relationship between bedrock exposure rates and soil labile organic carbon fractions (SLOCFs) in karst rocky desertification areas, and identify the limiting factors for SLOCFs. The results showed that concentrations and stocks of SLOCFs decreased with increasing soil depth, while light fraction organic carbon (LFOC) decreased with increasing bedrock exposure rate. The carbon pool management index and sensitivity index differed significantly under different bedrock exposure rates. The increase in bedrock exposure rate had a great impact on microbial biomass carbon (MBC), dissolved organic carbon (DOC), easily oxidized organic carbon (EOC), and soil organic carbon (SOC). The presence of secondary forest improved the integrity of karst landscapes without affecting the soil properties and concentrations and stocks of SLOCFs in karst rocky desertification areas.

Summary: The conversion of drylands to paddy fields on former wetlands in the Sanjiang Plain of northeast China enhances the soil organic carbon stock by promoting the accumulation of labile carbon fractions. Labile carbon fractions are more sensitive to this successive land-use change than recalcitrant carbon fractions.

Summary: This study quantified the soil organic carbon (SOC) and labile organic carbon (LOC) in different depths of soil at four sites in Yingluo Bay, China. The results showed that the natural expansion of mangroves has a positive impact on SOC and LOC, with the 80-year old mangrove site having the highest concentrations of SOC, LOC, and CMI. Therefore, promoting the natural expansion of mangroves can maximize the storage potential of soil organic carbon.

Summary: In this research, a modified sequential extraction scheme was used to isolate labile and recalcitrant soil organic matter (SOM) from organic rich soils and investigate the environmental chemistry of antimony (Sb) in SOM. The results showed that most of the Sb in organic matter was associated with humic substances and correlated significantly with total organic carbon (TOC) and nitrogen (N) contents, indicating the strong binding of Sb in SOM. The findings highlight the importance of Fe-Al-SOM bridging and recalcitrant SOM fraction in sequestering Sb.

Summary: The study found that straw residue is mainly retained in soil as particulate organic carbon (POC) and during decomposition, POC significantly increased while dissolved organic carbon (DOC) decreased. The addition of straw residue decreased the complexity of the bacterial microbial network but increased the complexity of the fungal network in IF and IFM treatments.

Summary: The highest contents of active SOC fractions were found in the organic manure (OM) treatment, while the highest maize yield was obtained in the chemical fertilizer with straw (CFS) treatment. Proteobacteria were widely distributed in all the fertilization treatments, and the dominant fungal phyla were Ascomycota in CK, CF and OM, and Basidiomycota in CFS treatment.
Soil bacterial/fungal communities and the active SOC fractions evidenced that fertilization, especially organic manure application, stimulated soil bacteria and fungi to participate in SOC turnover, contributing to improving the productivity and quality of black soil under sustainable management.

Summary: The effects of karst long-term vegetation restorations on soil carbon and enzyme activities were studied in Southwest China. Results showed that vegetation restorations significantly improved soil organic carbon accumulation and changed the distribution of labile organic carbon fractions. Different vegetation restorations had distinct effects on soil carbon and its labile fractions. This study provides scientific basis for the restoration of degraded karst ecosystems and intervention in carbon cycle based on land use regulation in Southwest China.

Summary: The influence of long-term chemical fertilization in paddy soils on SOC is attributed to the interaction between labile carbon and phosphorus fractions. In the 0-5 cm soil layer, easily oxidized organic carbon components and other soil physicochemical characteristics have a stronger interaction with SOC. An increase in DOC in this layer significantly lowers SOC, which is positively correlated with POXC but negatively correlated with SOC and WSC. The changes in SOC can be explained by the relationship between DOC and inorganic phosphate fractions under specific soil pH conditions.

Summary: Soil microbes play a crucial role in soil quality and productivity. Plastic film mulch (FM) combined with fertilization has greatly increased crop yields, but the effects on soil microbial communities, especially co-occurrence patterns, are unclear. This study found that nitrogen fertilization primarily affected bacterial community structure, while FM regulated fungal community structure. Network analysis revealed that FM led to an unstable co-occurrence network, while nitrogen fertilization increased both positive and negative links among microbes, indicating enhanced cooperation and competition.

Summary: This study investigated the content and composition characteristics of dissolved organic carbon (DOC) in soil under different agricultural practices using UV-Vis technology. The results showed that the use of gravel and film mulching significantly decreased the DOC content in topsoil, and film mulching also decreased the aromaticity and hydrophobicity of soil. Regression models established between CDOM/DOC, CDOM, SUVA(254), SUVA(260), and SUVA(280) showed high accuracy and can be used to predict soil DOC using UV-Vis technology. This study highlights the potential of UV-Vis spectroscopic technology in rapidly estimating soil DOM in agriculture.

Summary: The effects of long-term film mulching and primary N fertilization strategies on the microbial processes underlying N2O emissions from calcareous upland soils are poorly understood. The study conducted a two-year field experiment and found that long-term film mulching changed the N2O-related community composition and led to a significantly higher fraction of bacterial denitrification and/or nitrifier denitrification in most events. The results suggest that long-term film mulching and N fertilization strategies could impact the processes of N2O production and consumption, whereas denitrification was still the primary N2O production pathway.

Summary: This study investigates the effects of erosion degradation and long-term manure fertilization on soil properties and crop yield in Northeast China. Results show that erosion degradation and manure fertilization have lasting impacts on soil physical structure throughout the soil profile, while their effects on soil nutrient properties are focused in shallow layers. Manure fertilization significantly improves soil functional index (ISI) and maize yield for degraded soils. Erosion degradation has a greater influence on ISI and maize yield than manure fertilization.

The microstructure of the LPS also undergoes significant transformations with increased burial depth, transitioning from an overhead structure to a matrix structure. These findings highlight the importance of climate conditions on the structural strength of the LPS.

Summary: This study aimed to evaluate the impact of long-term nutrient management practices on P fractions and P adsorption-desorption behaviour of an acid soil with a soybean-wheat cropping system. The findings revealed that amorphous Fe and Al, which play a significant role in P fixation, increased due to cultivation. The NPK+Lime treatment offered the most balanced approach, improving both crop yield and P uptake while effectively managing P dynamics in the soil. On the contrary, long-term application of NPK+FYM in an acid soil may result in faster P saturation of adsorption sites and increase the chances of leaching and eutrophication. Tailored P fertilization strategies should be developed to better utilize the PFe and PAl fractions and supplementing applied P.
