“…It is involved in the decomposition of soil organic matter and can affect soil fertility and biological cycle [46]. The application of biochar in uncontaminated sugarcane soil and manganese-contaminated sugarcane soil could increase soil enzyme activity, and increased with the proportion of biochar application, which is similar to other research results [47]. Biochar provides a good living environment for microorganisms due to its large surface area and many pores, accelerates the ow of air, water and nutrients in soil, and improves microbial activity, thereby increasing enzyme activity [48].…”

In order to study the mechanism of soil organic carbon transformation and fixation in manganese-contaminated farmland, 100-day indoor constant temperature incubation experiments were conducted to analyze the characteristics of soil physical and chemical properties, organic carbon mineralization, organic carbon components and enzyme activities by applying different proportions (0%, 0.5%, 2%, 5%) of biochar. The results showed that the cumulative CO2 emission decreased by 15.78~36.87% compared with the control when different proportions of biochar were applied in the manganese-contaminated soil. The cumulative CO2 emissions were reduced by 35.29~57.29% compared with the control when different proportions of biochar were applied to the uncontaminated sugarcane field soil. The microbial carbon content of uncontaminated sugarcane soil was 28.49 mg·kg-1(0.5%),37.92 mg·kg-1(2%) and 39.42 mg·kg-1(5%), respectively, which were higher than that of manganese contaminated sugarcane soil 12.72 mg·kg-1 (0.5%),13.71 mg·kg-1(2%) and 15.10 mg·kg-1 (5%). The catalase activities of manganese-contaminated sugarcane soil were 0.13 mg·g-1·min-1 (0.5%), 0.21 mg·g-1·min-1 (2%) and 0.27 mg·g-1·min-1 (5%), respectively, which were lower than those of uncontaminated sugarcane soil 9.41 mg·g-1·min-1 (0.5%), 10.01 mg·g-1·min-1 (2%), 10.91 mg·g-1·min-1(5%). The results showed that compared with uncontaminated sugarcane field soil, the application of biochar in manganese-contaminated sugarcane soil had little effect on microbial biomass carbon content and catalase activity. The application of exogenous biochar had an auxiliary effect on carbon sequestration in manganese-contaminated soil, and the application of 5% biochar had the best carbon sequestration effect.

“…Biochar and vermicompost can effectively increase the organic matter content of the soil Bi et al, 2021), which accounts for less than 10% of soil's solid phase composition but plays a critical role in driving microbial activity and promoting mineral transformation. Their content also characterizes the nutrient status and quality of the soil (Wang Q. et al, 2022). Here, our findings revealed that the application of organic materials could enhance the content of organic matter and DOC concentration in the soil, both of which increase with the proportion of vermicompost.…”

The effects of different contents of biochar and vermicompost on the microbial and enzymatic activities of greenhouse soil were determined to provide a theoretical basis for improving the quality of greenhouse soil. The experiment was conducted in a greenhouse using potted tomatoes. Five treatments consisted of different amount ratios of organic amendments: 1% biochar (BC1), 3% biochar (BC3), 5% biochar (BC5), 3% vermicompost (VC3), and 5% vermicompost (VC5), with no addition of organic amendments as the control (CK). Compared with CK, the pH, organic matter content, and DOC concentration increased in treatment groups. The organic matter content of BC3 and BC5 significantly increased by 54.6% and 72.8%, respectively, and DOC concentration of BC3 significantly increased by 43.9%. Biochar and vermicompost significantly increased the diversity of bacterial and fungal communities in soil, as well as the abundance of Actinomycetes, Acidobacteria, Ascomycetes, and Aspergillus, and reduced the abundance of Aspergillus. The activities of urease and alkaline phosphatase were significantly increased, and the activity of nitrate reductase was inhibited in all treatment groups compared with CK. In addition, a highly significant positive correlation was observed among pH, Acidobacteria phylum abundance, and alkaline phosphatase activity in all treatments. DOC concentration was positively correlated with pH, organic matter content, Acidobacteria phylum abundance and alkaline phosphatase activity. Biochar and vermicompost were effective in improving the physicochemical properties of greenhouse soil, enhancing microbial diversity, and affecting enzymatic activities. Therefore, BC3 (3% biochar) had the most significant effect on community diversity and alkaline phosphatase and nitrate reductase activities. VC5 (5% vermicompost) had the best promotion effect on urease activity. This study highlights that biochar and vermicompost as organic amendments are recommended to improve the quality of greenhouse soils.

“…Soil enzyme activity, as a biological/biochemical indicator of soil quality, is closely related to the behaviour of soil microorganisms (Wang, Yuan, et al, 2022). Biochar has been reported to help increase sucrase activity, and the effect varies with biochar type, dose and soil type (Chen et al, 2020).…”

This study aims to explore novel, environmentally friendly technologies for converting organic waste into biochar for land application for sustainable management. However, the impact of biochar on the soil environment and crop yield depends on the specific feedstock and its interaction with the soil. Through pot experiments, we investigated the effects of three different biochars (sawdust biochar, rice straw biochar and coconut shell biochar) on the growth of Dictyophora rubrovolvata at two different input levels (1% and 2%). It was found that contrary to expectations, high input levels of sawdust biochar had a negative impact on D. rubrovolvata yield, while rice straw biochar and coconut shell biochar increased D. rubrovolvata yield by 16.0% to 159.1% and 54.4% to 64.0%, respectively, at the two input levels. The study revealed the key role of soil factors (such as total phosphorus, nitrogen/phosphorus ratio, water holding capacity, ammonium nitrogen, nitrate nitrogen, CaCl2‐phosphorus, dissolved organic carbon and invertase activity) in affecting the growth of D. rubrovolvata. Through structural equation modelling analysis, the application of sawdust biochar resulted in a low N/P ratio, thereby limiting the growth of D. rubrovolvata, while the application of straw biochar and coconut shell biochar promoted mushroom growth by increasing sucrase activity and DOC content. The increase in D. rubrovolvata biomass and nutrient content indicated the superiority of RSBC and CSBC as soil amendments. However, further research is needed to determine the appropriate application scenarios for SDBC. The findings also show that the application of biochar can help improve soil physicochemical biological properties, thus having potential benefits in sustainable agricultural practices. Overall, this study provides insights into the potential of biochar technology in sustainable agricultural practices, its role in improving soil quality and crop productivity, and explores for the first time a new field of biochar application in D. rubrovolvata cultivation.
