“…It might be due to higher inherent organic C and total N content in floodplain soil compared to terrace soil. Probably, vermicompost created a large positive priming effect on N mineralization in floodplain soil due to higher inherent organic C and total N content, which was not the case for terrace soil [77]. Floodplain soil might have a higher number of microbes due to higher inherent soil C. These microbes re-mineralize soil N and concurrently co-metabolize inherent soil organic C in floodplain soil when amended with vermicompost [78].…”

Although its mechanism of action, particularly under wetland condition, is not clearly understood, vermicompost, a good source of humus and plant nutrients, has been used as organic manure in many parts of the world in order to increase crop production. Here, an anaerobic incubation study and a field study were conducted to observe the nutrient release pattern from vermicompost and its influence on performance and nutrient uptake in wetland rice. Two contrasting soils, viz. highly weathered terrace soil and very young floodplain soil, were subjected to anaerobic incubation, while the field trial was conducted in the terrace soil with control (no amendments), mineral fertilizer, vermicompost (10 t ha−1) + mineral fertilizer, cow dung (10 t ha−1) + mineral fertilizer, vermicompost (20 t ha−1) + mineral fertilizer and vermicompost (local farmer’s practice) + mineral fertilizer treatments. Results showed that there were significant increases in nitrogen (N) and phosphorous (P) release in floodplain soil but not in terrace soil, suggesting that nutrient release from vermicompost is soil-dependent. The performance of Boro rice in terms of yield and yield attributes improved significantly in the case of the integrated application of vermicompost with mineral fertilizer. Specifically, combined application of mineral nutrients and vermicompost (10 t ha−1) significantly increased grain yield by 25% compared to the control treatment. We believe that this occurred due to an improvement in supply and subsequent uptake of nutrients, especially N and P. Altogether, our results suggest that vermicompost could increase crop performance under field conditions, and, although these effects may not be significant in short-term incubation studies, they may be even larger in floodplain soil.

“…Activated carbon in soil is vulnerable to microbial attack and is the main factor leading to soil carbon mineralization [30]. As the addition of carbon-rich additives alters the balance between stable and unstable carbon storage in soils, biochar may have positive or negative effects on carbon mineralization [71].…”

“…Researchers' conclusions on the impact of biochar on SOC mineralization are inconsistent [27][28][29], obtaining positive, negative, or neutral results. Adding aged sugarcane bagasse and rice husk biochar can inhibit soil respiration and reduce the absolute accumulation of CO 2 -C [30]. However, the application of straw or straw + biochar alone will increase CO 2 -C emissions in the soil, and only adding biochar alone (2%) can reduce them [31], indicating that biochar can reduce SOC mineralization.…”

To date, most studies have shown that biochar has great potential in carbon sequestration and reduction, as well as soil quality improvement. However, there is limited knowledge of its effect on soil organic carbon (SOC) fractions in tropical farmland. This study aimed to determine the impact of different types and rates of biochar applied in tropical farmlands on so SOC and its active fractions. The SOC, microbial biomass carbon (MBC), dissolved organic carbon (DOC), and soil mineralizable carbon (SMC) in the 0–30 cm soil layers under rice hull (R) and peanut shell (P) biochar treatments were measured. The results showed that the application of R and P biochar increased the contents, stocks, and cumulative stocks of SOC, MBC, and DOC in the 0–10 cm, 10–20 cm, and 20–30 cm soil layers. The contents, stocks, and cumulative stocks increased with increasing biochar application rates. Compared with CK, the ranges of the increased SOC, MBC, and DOC cumulative stocks were 10.76–46.36%, 30.04–195.65%, and 0.02–17.03%, respectively. However, the R60 and P60 had the lowest cumulative stocks of SMC, decreasing by 14.69% and 8.05%, respectively. The biochar treatment of more than 20 t ha−1 reduced the ratio of SMC:SOC and active fractions:SOC. Therefore, it can be inferred that the application of biochar improved the levels of SOC, MBC, and DOC, and the application of more than 20 t ha−1 biochar could decrease soil carbon mineralization, thus improving the stability of SOC in tropical farmlands.

“…Due to its excellent removal effectiveness, relative stability, low cost, and relatively smaller dosage, it offers an application potential in the degradation of organic contaminants in soil and water [163]. Sugarcane bagasse biochar has also shown promising results in increasing the organic matter content of organic carbon-deficient alluvial soils [164].…”

The effective management of agro-industrial waste plays a pivotal role in mitigating various forms of pollution. Sugarcane bagasse (SB), a substantial biomass waste generated in the sugar industry after cane juice extraction, necessitates sustainable handling. Although some sugar mills utilize wet sugarcane bagasse for fueling the milling process, a significant portion remains stockpiled and is often incinerated on-site, resulting in a highly flammable biomass that poses significant risks to the industry and its surroundings. Recognizing the importance of addressing this issue, researchers have identified the conversion of agricultural waste into biochar as an efficient means of harnessing energy following biomass devolatilization. There is scientific interest in the transformation of biomass into value-added products, including biochar, biogas, and biofuel. This comprehensive literature review delves into various pyrolysis processes applicable for converting sugarcane bagasse into char materials, showcasing its potential for diverse applications in line with current scientific interests.
