Therefore, we investigated the combined effects of salinization and warming on microbial activity and growth, examining CO₂ emissions (matter loss) and heat production (energy loss) during glucose metabolism. Soil from Elbe estuary was artificially salinized to medium (2.06 mS cm⁻¹) and high (3.45 mS cm⁻¹) levels, and ambient low salinity soil (0.93 mS cm⁻¹) served as the control. We examined the influence of a comprehensive +2 °C climate warming (20 vs. 22 °C) on soil respiration (CO₂ emission), heat release, enzyme kinetics (cellobiohydrolase, β-glucosidase, acid phosphomonoesterase and leucine-aminopeptidase) and microbial carbon use efficiency (CUE) across the microbial growth.</div><div>Increasing salinity did not impact respiration, heat release, microbial C and N content without glucose addition. However, activation of microorganisms with glucose brought force to the effect of salinity, and increasing salinity consistently retarded substrate uptake and growth. 2 °C warming affected substrate uptake and growth much more than increasing salinity. The calorespirometric ratio increased by 81–124% under high salinity compared to low salinity, with most of this increase occurring during the growth retardation stage. Enzyme activities increased by 68%–871% during the lag phase and remained relatively high throughout both the growth and retardation stages, regardless of salinity and temperature levels, suggesting the resistance of soil hydrolytic enzymes. The CUE gradually decreased and stabilized only at the very end of microbial growth, emphasizing the importance of considering the growth retardation for CUE estimation. Remarkably, disregarding the growth retardation stage resulted in a strong overestimation of the CUE accounting for 70%–98%.

Organic cropping systems aim to ensure sustainable production by promoting soil biodiversity to enhance soil functioning and regulate nutrient cycling through microbial processes. While taxonomic changes in microbial community composition in response to agricultural management are well described, there is still a fundamental knowledge gap when it comes to the impact of cropping system on soil functional diversity. Therefore, we revisited the 42-year-old DOK field experiment and used shotgun metagenomics to assess the metabolic potential and nutrient cycling capacities in organic and conventionally managed soils. The functional annotation of 11.4 billion reads to universal (EC, SEED), as well as carbon (CAZy), nitrogen (NCycDB) and phosphorus (PCycDB) cycling gene ontologies showed that manure fertilization was the main factor altering soil metabolic potential. But also, organic management practices, such as omission of synthetic pesticides and mineral fertilization induced changes in soil metabolic potential e.g. by enriching functional genes involved in organic phosphorus acquisition, nitrate transformation, organic degradation and non-hydrolytic carbohydrate cleavage. Conventional systems, receiving mineral fertilization and chemical plant protection, enriched genes associated with inorganic nutrient acquisition and transcriptional activity. The results of this study demonstrate that cropping systems influence the functional potential of soils, affecting fundamental mechanisms of nutrient cycling and thus soil regulating capacity. Consequently, cropping systems can be utilized to steer the regulating potential of agricultural soils and to lower the environmental impact of food systems.</div></div>","PeriodicalId":21888,"journal":{"name":"Soil Biology & Biochemistry","volume":"203 ","pages":"Article 109737"},"PeriodicalIF":9.8,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143124394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conversely, the development of anoxic conditions during thaw could lead to the microbial reductive dissolution of these Fe(III)-OC associations, resulting in a mobilization of the associated OC with unknown consequences for GHG release. In this study, we investigated the role of Fe(III)-OC associations (in the form of Fe(III)-OC coprecipitates) in soil GHG release during the collapse of previously oxic permafrost soils (“palsa”) and the inundation of seasonally anoxic soils (“bog”) at Stordalen Mire (Abisko, Sweden). We performed anoxic microcosm experiments using these two soils with the addition of ⁵⁷Fe-labeled Fe(III)-OC coprecipitates. The coprecipitates were reduced entirely after 42 days, with rapid reductive dissolution of 22 ± 7% and 20 ± 7% of coprecipitates within 1 day in palsa and bog soils, respectively. Emissions of GHG varied depending on soil type: in case of the palsa soil, cumulative CO₂ emissions increased by 43 ± 16% after addition of the Fe(III)-OC coprecipitates compared to a non-amended control, due to microbial Fe(III) reduction coupled to OC oxidation and likely additional OC input due to the release of Fe-bound OC. Concurrently, we observed an increase in activity of fermenting and complex OC-degrading microorganisms. Within the bog soil, it was notable that CH₄ emissions were temporarily suppressed, likely due to inhibition of methanogenesis by microbial Fe(III) reduction of the added coprecipitates, indicated by a decrease in <em>mcrA</em> gene copies.

The objective of this study is to determine which root trait composition optimizes plant mixture effects on SOC. To do so, we combined a global meta-analysis of 407 paired SOC content observations under mixed species vs. monocultures across grasslands and croplands, and root traits extracted from the GRooT database. The results show that high root mycorrhizal colonization and root tissue density for the species in the mixture have higher positive effects on SOC content. Our analysis also indicates that combining species with high similarity for these traits represents a preferable trait combination to increase SOC with plant mixtures, challenging the current paradigm around plant trait complementarity effects. We observed that the positive response of SOC content to species mixtures was tightly associated with increased root biomass and soil microbial biomass carbon, indicating an important contribution of belowground and microbial residuals to SOC. Additionally, SOC enhancements by plant species mixtures were more likely to be realized in regions with high precipitation, clay-rich soils, and when legumes are present.

However, it can also lead to N losses and environmental degradation under certain conditions. While numerous studies have examined autotrophic nitrification at individual sites, there is a lack of broad-scale, systematic investigations across diverse biomes, soil types, and climatic conditions. To address this gap, we analyzed data from 52 studies that used shaken slurry or aerobic incubation experiments that used chemical inhibitors (1-octyne and acetylene) to distinguish autotrophic nitrification driven by different taxa of ammonia oxidizers. Our analysis showed significant variation in nitrification rates, N₂O emissions, and N₂O yield across different ecosystems and fertilizer types. Croplands and soils treated with organic fertilizers exhibited the highest risk of N losses, whereas partially substituting mineral fertilizers with organic fertilizers showed the potential in reducing this risk. The observed inconsistent variations in autotrophic nitrification rates and N₂O emissions are likely due to changes in N₂O yield. Optimal temperatures for autotrophic nitrification were higher for ammonia-oxidizing archaea than for ammonia-oxidizing bacteria and varied across ecosystems and fertilizer types, reflecting the unique environmental conditions shaping ammonia oxidizer communities. The abundance of ammonia oxidizers was the primary factor regulating total autotrophic nitrification rates. Based on these findings, we suggest two strategies to control autotrophic nitrification: reducing substrate availability by incorporating organic or mixed fertilizers and applying nitrification inhibitors.
