However, there are controversial research findings regarding the applicability of biochar for the enhancement of soil physicochemical properties and agricultural (crop) yield, particularly under conditions of wastewater irrigation in agricultural production. This study investigates the effects of controlled soil salinity levels (1 ‰ and 3 ‰), induced using sodium chloride, and the targeted application of biochar in a pot experiment. The study examines the impact on physicochemical characteristics of different soil layers, physicochemical properties, and physiological responses of rice plants irrigated with aquaculture wastewater. It also delves into soil microbial diversity and the predominant bacterial species. The research findings reveal that biochar exerts a significant influence on soil properties and nitrogen content in saline environments. The addition of biochar enhanced soil electrical conductivity (EC), modulated the distribution of organic carbon, and altered nitrogen transformation processes within the soil. Consequently, biochar application resulted in a 14.2 % and 6.81 % increase in rice yield at 1 ‰ and 3 ‰ salinity levels, respectively. Furthermore, biochar increased leaf area by 25.3 % and 45.9 % in 1 ‰ and 3 ‰ salinity stress separately and enhanced the nitrogen content (TN) in leaves by 28.6 % when the soil salinity is 1 g/kg, demonstrating a positive impact on nitrogen uptake. Additionally, biochar has shown potential in mitigating nitrous oxide (N₂O) emissions. Its addition led to a reduction in the relative abundance of <em>Actinobacteria</em> while increasing the relative abundance of <em>Firmicutes</em>.

To address this, a field experiment with four treatments - inorganic fertilization (IF), organic fertilization (OF), inorganic fertilization with biochar addition (B + IF), and organic fertilization with biochar addition (B + OF) - was conducted within a wheat cropping system on a sandy loam soil. The study aimed to elucidate the role of biochar-induced changes in abiotic factors and plant root inputs in shaping the soil micro-food web. Results showed that the effects of biochar on the soil micro-food web varied depending on the fertilization context. Under inorganic fertilizer, biochar strongly increased the abundance of total microbes and total nematodes, but reduced the biomass of omnivores-predators. However, biochar combined with organic fertilizer had a positive effect on the abundance and biomass of total microbes as well as the biomass of total nematodes and omnivores-predators. In addition, biochar with inorganic fertilizer affected the abundance of microbes and nematodes through direct pathways and indirectly affected microbial biomass and abundance mediated by reducing NH₄⁺-N and DOC content. In contrast, in organic fertilization, the improvement of root biomass and soil pH were the most direct drivers of variation in microbial abundance. These findings highlight the potential of biochar as a strategic amendment to optimize soil micro-food web dynamics, with fertilizer type playing a critical role in determining its effectiveness.

Based on a fire experimental study in subtropical forest ecosystem, we investigated the alterations in soil properties and microbial community across two seasons. The results showed that soil bacterial richness remained unchanged by fire in both seasons. In contrast, soil fungal richness decreased in spring but increased in autumn at burnt sites, indicating the amplified seasonal variation induced by fire. In addition, fire had a significant impact on soil microbial community composition. Specifically, it elevated the relative abundance of Actinobacteriota but reduced that of Acidobacteriota and Verrucomicrobiota, which was related to increased temperature, pH, and decreased nitrogen resulting from fire. The relative abundance of Ascomycota increased following fire, whereas the relative abundance of Basidiomycota decreased. These shifts in soil fungal community were mainly related to lower soil carbon:nitrogen ratio. Furthermore, bacterial community was more responsive to environmental changes than fungal community.

Earthworms, a key component of soil fauna, are known to increase N₂O production. While existing research has focused mainly on soil physicochemical management and microbial interactions, limited attention has been paid to how biochar interacts with soil fauna in relation to N₂O emissions. To investigate this, an incubation experiment was conducted to analyze how various biochars, including corn straw (CS), rice straw (RS), wheat straw (WS), nutshell (NS), wood chip (WC), rice husk (RH), apricot shell (AS), and peach shell (PS) biochar, affect earthworm (<em>Amynthas cortices</em>) enhanced N₂O emissions. Biochar addition reduced earthworm enhanced N₂O production and decreased the cumulative earthworm burrowing length compared to control. Rice straw biochar was the most effective, releasing the lowest earthworm enhanced N₂O emission at 73 μg kg⁻¹ soil and having the shortest cumulative burrowing length at 48.6 cm, whereas wood chip biochar had the least impact, with earthworm enhanced N₂O reaching 307 μg kg⁻¹ soil. The drilosphere influenced by earthworms' activity demonstrated increased pH, C/N ratio, mineral nitrogen (MN), dissolved organic carbon (DOC), and microbial biomass carbon (MBC) compared to the bulk soil, though the extent of these changes varied with the type of biochar applied. The biochar addition altered the micro-environment within the earthworm gut, including O₂ concentration and pH levels, thereby affecting the N₂O related microbial community in the drilosphere. This was evidenced by changes in the ratio of <em>nirK</em> + <em>nirS</em> to <em>nosZ</em> genes and the abundance of ammonia-oxidizing archaea and bacteria gene copies. Hierarchical partitioning analysis revealed that the biochar's properties primarily influenced earthworm burrowing activity, the dominant factor affecting earthworm enhanced N₂O emissions, followed by MN, DOC, and MBC content in the drilosphere. The impact of gut-derived microbes on N₂O emissions was comparatively insignificant. These findings highlight that biochar amendment can mitigate earthworm induced N₂O emissions, primarily by modifying earthworm activity, which is strongly influenced by the biochar's physicochemical characteristics.</p></div>","PeriodicalId":12057,"journal":{"name":"European Journal of Soil Biology","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142232756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we determined the response of the methane-driven interaction network to different methane concentrations (∼1.5 %_v/v, 3 %_v/v, and 7 %_v/v), indicative of different levels of energy flow through the soil food web, using a stable isotope probing approach with ¹³C-methane coupled to a co-occurrence network analysis in a microcosm study. The accumulated ¹³C-atom fraction in the total carbon content increased from 1.08 % (background level) to an average of 7.2 % in the incubation under 7 %_v/v methane, indicating that the carbon-flow <em>via</em> the methanotrophs can significantly contribute to the total carbon in the rice paddy soil. The ¹³C-enriched 16 S rRNA gene sequencing analysis revealed the predominance of gammaproteobacterial methanotrophs and <em>Methylocystis</em>. The composition of the actively growing (¹³C-labelled) bacterial community was dissimilar in the incubation under ∼3 %_v/v than under 1.5 %_v/v and 7 %_v/v methane.

It thus appears that moderate methane concentrations fostered closer associations among members of the methane-oxidizing community.
