“…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.

“…Previous studies have shown that green oxygen-carrying biochar could improve water quality and reduce N 2 O emissions [14,15]. At the same time, its unique microporous structure provides an ideal habitat for microorganisms [16], and biochar is able to improve the soil microenvironment, soil microorganism, and soil enzyme activities [17,18]. However, biochar may inhibit the growth of microorganisms due to the adsorbed soil organic carbon and other low-molecular-weight organic matter [19].…”

“…Biochar impacts plant growth [16]. Biochar is applied in aquatic vegetable cultivation, and it not only improves the quality and yield, but also reduces the edible risk [18]. However, Chi et al [11] suggested that biochar's amendment to sediments had a negative effect on the growth of Vallisneria spiralis L. In the presence of polycyclic aromatic hydrocarbons (PAHs), the adsorption of biochar made the PAHs more persistent in water [11,20].…”

Ecological restoration in dredging areas has attracted increasing attention. The reconstruction of a submerged plant ecosystem is an important method for aquatic ecosystem restoration. This study has systematically investigated the effect of biochar-improved sediment on the plant growth and decontamination efficiency of a constructed ecosystem. Microbial community composition and structure in the sediment were detected. The results showed that a supplement of 20 mg/g of biochar significantly increased the biomass of the submerged plants compared with other doses (0, 10, and 40 mg/g). The biomass and chlorophyll content were significantly inhibited by supplementing 40 mg/g of biochar. In the Ceratophyllum demersum L. system, TP and NH4+-N concentrations were significantly lower after treatment with 20 mg/g of biochar compared to other doses. In Vallisneria spiralis L. and Hydrilla verticillata (L. f.) Royle systems, NH4+-N, TP, and DO concentrations were significantly different among different biochar treatments. In general, 20 mg/g of biochar improved water quality in different submerged plant systems, while 40 mg/g of biochar had adverse effects on water quality, such as higher NH4+-N and TP concentrations. The dominant microbial community included Proteobacteria, Acidobacteria, Chloroflexi, Actinobacteriota, and Bacteroidota. The structure and function of microbial communities were different among submerged plants and biochar treatments. Our results proposed a construction strategy of submerged plants in the dredging area.

São Paulo.Biocarvão é um potencial aditivo para o solo agrícola e pode ser usado como um material adsorvente ecológico e econômico em outras aplicações como, por exemplo, substratos usados em cultivos de telhado verde. As propriedades do biocarvão são influenciadas por diversos parâmetros tecnológicos, principalmente a temperatura da pirólise e a matériaprima, e esta diferenciação pode levar a produtos com uma ampla gama de características. O biocarvão pode ser considerado como um sequestrador de carbono devido a sua elevada estabilidade, bem como pode ser empregado como material adsorvente na remediação de água. No presente estudo, foi avaliada a adição de biocarvão derivado de resíduo madeireiro em substrato utilizado em telhados verdes. Na primeira etapa do estudo, determinou-se a concentração de nutrientes e do íon sulfato pre...
