“…Previous studies have confirmed that biochar addition actively enhanced the soil ecosystem functions (Liang et al, 2017;Dong et al, 2022;Han et al, 2022;Ren et al, 2023). In this study, we also found that the different gradients of biochar amendment improved the soil multifunctionality in the early stage (P < 0.01) (Figure 1A).…”

IntroductionSoil microbes are central in governing soil multifunctionality and driving ecological processes. Despite biochar application has been reported to enhance soil biodiversity, its impacts on soil multifunctionality and the relationships between soil taxonomic biodiversity and ecosystem functioning remain controversial in paddy soil.MethodsHerein, we characterized the biodiversity information on soil communities, including bacteria, fungi, protists, and nematodes, and tested their effects on twelve ecosystem metrics (including functions related to enzyme activities, nutrient provisioning, and element cycling) in biochar-amended paddy soil.ResultsThe biochar amendment augmented soil multifunctionality by 20.1 and 35.7% in the early stage, while the effects were diminished in the late stage. Moreover, the soil microbial diversity and core modules were significantly correlated with soil multifunctionality.DiscussionOur analysis revealed that not just soil microbial diversity, but specifically the biodiversity within the identified microbial modules, had a more pronounced impact on ecosystem functions. These modules, comprising diverse microbial taxa, especially protists, played key roles in driving ecosystem functioning in biochar-amended paddy soils. This highlights the importance of understanding the structure and interactions within microbial communities to fully comprehend the impact of biochar on soil ecosystem functioning in the agricultural ecosystem.

“…However, it is still unclear whether and how biogas-slurry and biochar application affect soil multifunctionality in a poplar plantation during long-term afforestation. Ren et al (2023) conducted a six-year field experiment in a new poplar plantation based on a reclaimed coastal area to evaluate whether and how biogas-slurry and biochar application affect soil multifunctionality. The study found that both biogas-slurry and biochar could enhance multiple ecosystem functions, such as carbon stock.…”

“…Biochar and biogas slurry are widely used to improve agricultural soil, which can improve soil properties and affect the migration of soil nutrients ( Guo et al., 2014 ; Liang et al., 2023 ). At present, the research on the application of biochar and biogas slurry is mainly focused on the improvement of dryland soil properties ( Liao et al., 2022 ; Zhang et al., 2022 ; Ren et al., 2023 ), the effect on the properties of flooded soil is rarely investigated ( Wang et al., 2023 ). This study focused on exploring the persistent effects of biochar and biogas slurry co-application on soil nitrogen nutrients and lotus root growth characteristics.…”

Using swine manure biochar and biogas slurry in agriculture proves to be an effective strategy for soil improvement and fertilization. In this study, a pot trial on the growth of lotus root was conducted to investigate the persistent effects of applying 350°C swine manure biochar (1% and 2%) and biogas slurry (50% and 100%) on soil nitrogen nutrient and lotus root quality. The results showed that compared to chemical fertilizer alone (A0B0), swine manure biochar significantly increased soil nitrogen content after one year of application. The contents of total nitrogen (TN), alkali-hydrolyzed nitrogen (AHN), ammonium nitrogen (NH4+-N), and nitrate nitrogen (NO3− −N) increased by 17.96% to 20.73%, 14.05% to 64.71%, 17.76% to 48.68% and 2.22% to 8.47%, respectively, during the rooting period. When swine manure biochar was present, the application of biogas slurry further elevated soil nitrogen content. The co-application of swine manure biochar and biogas slurry significantly increased soil nitrogen content, and the 100% nitrogen replacement with biogas slurry combined with 2% swine manure biochar (A2B2) treatment exhibited the most significant enhancement effect during whole plant growth periods. Soil enzyme activities, including soil protease (NPT), leucine aminopeptidase (LAP), b-glucosidase (β-GC) and dehydrogenase (DHA), showed a tendency to increase and then decrease with the prolongation of lotus root fertility period, reaching the maximum value during the rooting period. Compared to A0B0, the treatment with 2% swine manure biochar had the most significant effect on enzyme activities and increased the lotus root’s protein, soluble sugar, and starch contents. Nitrate content decreased with the application of 2% swine manure biochar as the amount of biogas slurry increased. In conclusion, swine manure biochar effectively improved soil nitrogen content, enzyme activity, and lotus root quality. Even after one year of application, 2% swine manure biochar had the best enhancement effect.
