Then the study introduces an eco-novel strategy for repurposing expended sugarcane bagasse (SGO) that has been used to clean up lubricating oil into biochar and pragmatically analyzes the impact of sorbed oil on the resulting biochar. A non-electric and low-temperature auto-thermal, top-lit updraft gasifier was employed to carbonize the bagasse feedstocks for 120 min. At peak temperatures of 311 °C and 321 °C, a yield of 31.30% and 23.47 wt.% was recorded for SGB and SGO, respectively. The SEM, FTIR, and BET analyses revealed that the sorbed lubricating oil had some positive impact on SGO. Firstly, the textual profile analysis showed that both biochars are mesoporous, with SGO having a superior surface area of 542.265 m²/g compared to SGB (527.645 m²/g). The FTIR analysis also reveals the presence of different O-containing functional groups, with SGO having more carbon networks in these functional groups. The SEM analysis shows that the biochar samples have a heterogeneous mixture of particles with various layered structures, shapes, and sizes. More specifically, SGB has a striated structure with slit-shaped pores, while SGO has a network of blind, open, and closed interconnected pores with a glossily rough structure. The improved SGO biochar exhibits meritorious potential in practical applications like fillers for composite production, and energy storage devices, thus demonstrating an eco-conscious solution for repurposing expended biosorbent and promoting environmental sustainability.</p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"27 4","pages":"1290 - 1299"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145160618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nitrogen is an essential nutrient for crop growth. It has been generally accepted that nitrogen fertilization increases sugar beet yield and improves quality. However, a systematic analysis investigating the effects of nitrogen fertilization on sugar beet yield and sugar content is currently lacking. In this study, we analyzed 814 data pairs from 42 studies to make a global meta-analysis of nitrogen fertilization on yield and sugar content. Under most climatic conditions, nitrogen application showed a positive effect on root yield, with the maximum effect size when mean annual average precipitation (MAP) ≤ 300 mm, means mean annual air temperature (MAT) &gt; 10 °C, and means mean annual sunshine (MAS) &gt; 2500 h. While nitrogen application basically showed a negative effect on sugar content, especially when MAP &gt; 300 mm, MAT &gt; 10 °C, and MAS &gt; 2500 h. Similar trend was found in terms of soil conditions, with an exception in clay soil. Nitrogen application had a positive and significant effect on root yield under all the management practices, with the maximum effect size when nitrogen application frequency ≥ 5, 150 kg ha⁻¹ ≤ nitrogen application rate ≤ 300 kg ha⁻¹, and 1 × 10⁵ plants·ha⁻¹ ≤ plant density ≤ 1 × 10⁵ plants·ha⁻¹. The effect of nitrogen application on sugar content was insignificant and more complicated. There was an insignificant linear and negative relationship between root yield and sugar content effect. It can be concluded that nitrogen application led to a positive and significant response on root yield, yet a negative and insignificant response on sugar content. And the optimal nitrogen application rate should be determined by local climatic factors, soil conditions, and management practices. This meta-analysis improved our understanding of crucial factors influencing the effects of nitrogen fertilization on root yield and sugar content and provided guidance for optimizing nitrogen fertilizer application.</p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"27 4","pages":"1258 - 1268"},"PeriodicalIF":2.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of varying ON application rates (0, 2, 4, 6, and 8 t ha⁻¹) and MN rates (0, 40, 80, 120, and 160 kg ha⁻¹), as well as their interaction, were evaluated over two crop seasons.

Results confirmed that poultry litter can replace ammonium nitrate for supplying N, P, and K to sugarcane. However, higher rates of ON and MN negatively impacted juice quality parameters, including °Brix, apparent sucrose content (POL), and purity. Excessive ON-MN combinations also reduced total sugar recovery. A balanced application of 4.2 t ha⁻¹ of ON combined with 120 kg ha⁻¹ of MN resulted in the highest sugar yield, averaging 22.845 t ha⁻¹.

The analysis focused on the influence of blade geometry and structural parameters on critical cutting speed (CCS) and maximum cutting force (MCF).

Band placement of fertilizer increased the leaf area index (LAI) at the grand growth stage to 5.280. Applying N and K in three splits enhanced LAI to 5.637 at the grand growth stage. Placement methods and nutrient management schedules significantly influenced the harvest stage’s total dry matter accumulation (TDMA). Band placement also increased TDMA in sugarcane by 12.99% (31.61 t/ha) compared to broadcasting. However, application of N and K in five splits enhanced TDMA by 29.57% (35.10 t/ha) over three splits. Microbial activities in soil were also determined through microbial biomass C &amp; N and respiration.

Notably, the control group without any nanoparticle addition yielded a modest 11.157% bioethanol. However, the introduction of 100 ppm of CoFe₂O₄ nanoparticles significantly enhanced ethanol production, achieving 52.157%. Additionally, increasing the concentration of the CoFe₂O₄/g-C₃N₄ composite from 0 mg to 100 ppm resulted in a notable improvement, reaching an ethanol yield of 35.44%. Even with 100 ppm of g-C₃N₄ alone, ethanol production increased to 23%. To further optimize the fermentation process, the study also examined the effects of visible light irradiation on ethanol production, both in the presence and absence of these nanomaterials. The results revealed that light irradiation could stimulate bioethanol production by 15.44% compared to the control. When light was combined with nanoparticles, the stimulatory effects were even more pronounced, indicating that light-activated nanoparticles represent a promising strategy for enhancing ethanol yields. The findings highlight the potential of CoFe₂O₄ nanoparticles, particularly when photoactivated, to significantly elevate ethanol yields from banana peels. Furthermore, the study identifies the optimal concentration of the CoFe₂O₄/g-C₃N₄ composite as a viable pathway for sustainable bioethanol production.
