Summary: Land-use conversion has significant impacts on the geochemical and microbial properties of tropical soils. The chemical index of alteration (CIA) is found to be sensitive in reflecting the geochemical controls on microbial nutrient acquisition in tropical soils. Microbial communities adjust their nutrient acquisition strategies based on the geochemical soil properties, which can affect carbon (C) input, storage, and release in tropical soils.

Summary: A meta-analysis of 481 paired measurements from cropland soils showed that cropland management practices significantly influence microbial necromass accumulation and its contribution to soil organic carbon (SOC). Nitrogen fertilization, cover crops, no or reduced tillage, manure, and straw amendment all increased microbial necromass accumulation. The optimal conditions for microbial necromass accumulation and its contribution to SOC sequestration require site-specific management.

Summary: Soil organic amendments can alter microbial communities and their resilience to environmental stresses, impacting carbon and nitrogen transformation. This research investigates the impact of temperature change rates as a microbial stressor and evaluates the potential use of organic amendments in steering soil ecological response. The results indicate that organic amendments can mitigate the sensitivity of soil to temperature changes.

Summary: The study revealed that soils derived from different geochemically contrasting parent materials in tropical montane forests have varying effects on microbial properties, with soils from mafic parent material exhibiting the highest microbial biomass C and potential extracellular enzyme activity. Additionally, microbial investments in carbon and phosphorus acquisition differ across soil depths.

Summary: Microbial diversity plays an important role in the decomposition of soil organic matter. This study examined the relationship between microbial diversity and decomposition by manipulating microbial diversity in soils. The results showed that microbial diversity was positively correlated with the decomposition of organic matter per gram of carbon in the soil, indicating that microbial diversity supports decomposition when the microbial community is limited by available carbon. However, microbial respiration per gram of soil was negatively correlated with bacterial diversity and positively correlated with fungal biomass, suggesting that decomposition rate is controlled by the amount of fungal biomass in the absence of carbon limitation. The addition of grass litter also had a priming effect on the initial stage of decomposition. Therefore, the relationship between microbial diversity and the rate of decomposition may be complex and dependent on the context.

Summary: Land-use changes have significant impacts on soil quality and microbial communities. The relationship between soil quality and soil microbial communities needs further understanding. Different agricultural management practices have contrasting effects on microbial interactions and functions. Changes in soil quality determine the key taxa and functions of soil microbial communities.

Summary: This study analyzed the functional diversity and metabolic potentials of microbial communities in the rhizosphere of former grassland and intensively cultivated land, revealing differences in the dominant functional categories and abundance between the two. However, no significant difference was observed in the alpha diversity studies between the two fields.

Summary: A study conducted in Hungary investigated the effects of organic amendments and mineral N fertilization on soil microbial biomass, aggregate stability, and organic carbon content. The results showed significant impacts of organic amendments on these soil properties, with different levels of variability at different time scales. The study also revealed that the effects of organic amendments and temporal variability may explain the weak correlation between aggregate stability and microbial biomass.

Summary: This study found that applying compost improved soil organic carbon, aggregate stability, EPSac, and total microbial biomass while also influencing microbial community structures, particularly in turfgrass. Deficit irrigation treatments resulted in higher quantities of soil EPSac per unit microbial biomass, with indicators of microbial physiological stress being closely associated with soil EPSac production.

Summary: In this study, the effects of silicon calcium magnesium potassium fertilizer, calcium magnesium phosphate fertilizer, and lime on improving acidic soils were investigated. It was found that the application of these amendments transformed the active fractions of aluminum to stable ones. Furthermore, these amendments significantly influenced the composition of microbial community in rhizosphere soils, improving soil microbial function and dehydrogenase activity. The study also established an index, AIV, to assess the relationship between acidity-related indicators and other soil properties. The results indicated that SIAs had minimal effect on the fungal community structure but greatly influenced the abundance of bacteria, particularly Acidobacteria, Nitrospirae, and Crenarchaeota. These findings suggested that SIAs optimized soil environment for rice growth by reducing aluminum mobility, enhancing soil microbial function, and increasing soil fertility.

Summary: The study found that the application of heavy metal passivators such as lime, Si fertilizer, and gypsum can improve microbial diversity and function in Cd contaminated paddy soil. Lime increased the abundance and richness of prokaryotic microbes, while gypsum increased evenness of eukaryotic microbes. Si fertilizer resulted in increased evenness of both prokaryotic and eukaryotic microbes.

Summary: Land-use practices and climatic conditions can alter soil organic carbon content and influence soil microorganisms. Crop residue incorporation has the potential to mitigate carbon losses and promote microbial diversity. A glasshouse experiment was conducted to investigate microbial functional diversity and activity with straw amendments in arable and grassland soils. The gene expression related to organic matter degradation differed between land-use systems, with straw addition enhancing gene expression in arable soils. After one month, arable soils showed similar patterns to grasslands. The findings suggest that amendments can increase microbial diversity in low organic carbon arable soils and promote soil carbon sequestration in grasslands.

Summary: Soil microbial nutrient limitations have significant impacts on microbial processes and ecosystem functionality. The response of soil microbial nutrient limitations to earthworms, which play an important role in terrestrial ecosystems, has been rarely studied. This research finds that earthworms can reduce microbial carbon limitation but enhance phosphorus limitation in the presence of plants, depending on soil type and moisture conditions.

Summary: The study found that applying manure fertilizer alone can increase the storage of soil organic carbon and total nitrogen in subsurface layers. Climate variables only affect the storage of organic carbon and total nitrogen in the topsoil. Balancing soil carbon and nitrogen sequestration with crop yields is important in management strategies.

Summary: This study found that a combination treatment of lime, pig manure, and straw is effective in improving soil acidity and increasing crop yield. Pig manure treatment had the greatest impact on maize growth, while lime treatment significantly affected soil pH. Furthermore, over-application of pig manure could have negative impacts on aquatic ecosystems.

Summary: Soil fumigation can affect soil nutrient cycling processes and soil fertility by influencing soil beneficial microorganisms. However, the impact of combined application of fumigant and fungicide on soil phosphorus availability is still unclear. This study investigated the effects of the fumigant chloropicrin (CP) and the fungicide azoxystrobin (AZO) on soil phosphatase activity and soil P fractions in ginger production. Results showed that AZO application alone increased soil labile P fractions in the short term but decreased soil phosphatase activity in the long run. CP fumigation reduced phosphatase activity but increased the proportions of labile P fractions to total P. The combined application of CP and AZO had a synergistic effect on soil phosphatase activity and soil P fractions.
