The application of coal fly ash (CFA) to soil may change soil physico-chemical characteristics, thereby influence carbon mineralization, but its effect on CO 2 production is not yet clear. Consequently, the purpose of this study was to quantify the CO 2 production of tropical peatlands that received N fertilizer and CFA. In the laboratory experiment, CFA equivalent to the application of 150 Mg·ha −1 in the field was added to peatlands with and without N fertilizer. These mixtures were then incubated at 70% water-filled pore space (WFPS) for 30 days at room temperature. Carbon mineralization was measured on a 5-day basis, while several chemical characteristics of treated peatlands, including pH, hot water-soluble C, exchangeable-Ca, -Mg, -Fe, and -Al were measured at the conclusion of the incubation period. This study identified that N fertilizer application increased the CO 2 production of tropical peatlands from 29.25 g·kg −1 to 37.12 g·kg −1 . Furthermore, the application of CFA on tropical peatlands reduced CO 2 production of tropical peatlands with and without N fertilizer. Decreasing the amount of hot water-soluble carbon from peatlands may account for the reduced CO 2 production of peatlands with CFA. The study also showed that exchangeable-Ca, -Mg, -Fe, and -Al increased in peatlands with CFA application, and these multivalent cations were also attributed to a reduction of CO 2 production. In conclusion, the negative effects of N fertilizer application on peatlands in increasing CO 2 emission may be reduced by the application of CFA.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"44 2","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139158432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Revegetation of reclaimed land is a priority in restoring ecosystems disrupted by mining activities. This study aims to assess the success of the direct planting method in accelerating the growth of Pterocarpus indicus plants in coal mining reclamation areas. Field data and observations are used to evaluate the growth of plants directly planted in reclaimed post-mining land. The growth parameters observed include plant height, stem diameter, and leaf count using both seedling and stem-cutting planting materials. The research results indicate that the direct planting method has a significant impact on accelerating the growth of Pterocarpus indicus plants. The plant height, diameter, and leaf count growth from the ANOVA test results showed a significant effect or significance at p<0.05 for the interaction between planting material, fertilizer, and dosage. The Duncan test results for the average plant height, stem diameter, and leaf count indicate the optimal use of bokashi fertilizer. The effective bokashi fertilizer dosage for each variable is 3 kg/plant - ing hole, resulting in a plant height of 102.31 cm; 3 kg/planting hole, resulting in a stem diameter of 24.26 cm; and 5 kg/planting hole, resulting in a leaf count of 41.32.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":" 14","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138611188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By combining olive pulp (OP) and wheat straw (WS) treated with Phanerochaete chrysosporium and Fusarium oxysporum, we enhance digestibility and sustainability. Five mixing ratios were examined: 100% OP (OP), 75% OP and 25% WS (MOP), 50% OP and 50% WS (OPWS), 25% OP and 75% WS (MWS), and 100% WS (WS). Fungal treatment and ratios influence cellulose-lignin dynamics. MOP increased cellulose (13.1), OP showed an initial decrease (-8.51, -5.88 for P. chrysosporium, F. oxysporum ), with cellulose rising from 4 to 8 weeks, then declining. Lignin degradation differed (P < 0.001), P. chrysosporium was efficient (24.22%±13.75 to 31.57% ± 20.65), MWS remarkable, and OPWS stable. Mixed substrates showed higher IVTD_imp (58.56% ± 16%, 54.18% ± 20%, 36.83% ± 18%), OP and WS lower (26.25% ± 11%, 14.43% ± 7.48%). Enhanced IVTD (4-12 weeks) seen, OPWS and MOP excelling, WS lower. In conclusion, this study unveils the potential of fungal-treated feed optimization through substrate composition and tailored treatment durations. By leveraging synergistic effects and optimizing treatment timelines, we enhance livestock feed sustainability while addressing waste management concerns. This comprehensive approach holds promise for achieving both nutritional and environmental goals in livestock production.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":" 3","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138616456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, biostimulants are a sustainable option to promote rice yield and improve soil quality. This research focusses on the use of gamma-polyglutamic acid (γ-PGA) and Bacillus subtilis cells as biostimulants to improve rice growth and soil quality. The sand culture technique was performed to determine germination and growth of rice seedlings, and greenhouse experiments were conducted to evaluate the performance of rice yields. The soil quality was investigated by measuring physical and chemical characteristics. The results demonstrated that γ-PGA and B. subtilis cells were efficient biostimulants for germination by significantly increas - ing the seedling vigor index. γ-PGA considerably improved the growth parameters of 21-day-old rice seedlings by significantly increasing dry weight, total sugar, total free amino acids and total chlorophyll content compared to the control. In greenhouse experiments, γ-PGA had a positive influence on all physical characteristics and rice grain yield indicators compared to B. subtilis cells and controls. Furthermore, γ-PGA and B. subtilis cells had a stronger impact than controls on improving soil quality, and γ-PGA had a notable effect on soil physical properties rather than on their chemical properties. Based on these findings, γ-PGA outperformed B. subtilis cells as a natural biostimulant to increase rice productivity and improve the quality of paddy soil.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"124 12","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138608263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current investigation is an experiment performed in a lab setting using a batch-operated anaerobic digestion reactor with a mesophilic temperature of 35°C. This study examined the generation of experimental biogas and biodegradability .The effect of pretreatment by methanogenic bacteria growth medium on anaerobic digestion of sewage sludge was studied on three different concentrations of growth media, a control, and a low, medium and high concentration of culture medium, with cumulative biogas production of 610N ml /gVS added, 750 N ml /gVS added, 900 N ml /gVS added, 10 N ml /gVS added, respectively, with biodegradability rate of 52.16%, 56.5%, 74.04%, 28.70% respectively. Biogas production was enhanced at a medium concentration of culture medium and inhibited at a high concentration during anaerobic digestion of sewage sludge. Additionally, a theoretical biogas estimate was evaluated using four kinetic models (Logistic function, Modified Gompertz, Transference function, and First order); which were utilized to match the experimental biogas generation process involving the anaerobic digestion of untreated and pretreated sewage sludge by various concentrations of growth media of methanogenic bacteria . The kinetic find - ings demonstrated that both models, Modified Gompertz and Logistic function, were useful for predicting biogas output and matched experimental biogas production.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":" 21","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138612403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
