Cependant le stockage et la séquestration du carbone organique dans le sol permettent d’atténuer ces problèmes tout en offrant une partie de la solution au réchauffement climatique. Cette étude suggère une seconde caractérisation du statut organique des sols jusqu’à 100 cm de profondeur en Haïti. Nos résultats ont montré une grande variabilité verticale des concentrations de carbone et d’azote total. Suivant une approche de mesure directe sur 90 parcelles, nos analyses statistiques ont montré une forte concentration en carbone organique total dans les 10 premiers centimètres du sol (3,7 g 100 g-1). Il en est de même pour la concentration en azote totale avoisinant 0,275 g kg-1. Dans la couche 50-100 cm, des faibles teneurs en carbone et en azote estimées respectivement à 1,125 g 100 g-1 et à 0,025 g kg-1 ont été repérées. La variabilité des stocks organiques a été également constatée au niveau des types de sol, de la topographie et des systèmes de culture. Ainsi, les plus élevés et les plus faibles stocks de carbone organique ont été enregistrés respectivement dans le système agroforestier (196,44 MgC. ha-1) et le système de pâturage (128,55 MgC. ha-1). Les stocks de carbone organique varient de 80,57 MgC. ha-1 pour les Haplic Cambisols positionnés dans les versants à 203 MgC. ha-1 pour les Rendzic Leptosols et Epileptic Cambisols (RELEC) qui sont majoritairement situés dans la vallée. L’effet significatif au seuil de 5% a été observé entre les systèmes de culture et les types de sol. Ces résultats indiquent que la restauration des sols requiert des apports de matières organiques exogènes et endogènes par l’implémentation des pratiques agricoles résilientes. Ils ont aussi permis d’établir le lien entre la fertilité des sols et la restitution de la matière organique en vue d’une amélioration de la sécurité alimentaire. Il a été ainsi crucial d’identifier les systèmes de culture et les pratiques agricoles répondant au mieux au stockage de carbone et d’azote total. \u0000Climate change poses a major threat to food security, due to its strong impact on agriculture. However, the storage and sequestration of organic carbon can mitigate these problems and offer part of the solution to global warming. This study suggests a second characterization of the organic status of soils up to 100 cm soil depth in Haiti. Our results showed a large vertical variability of carbon and total nitrogen concentrations. Following a direct measurement approach on 90 plots, our statistical analyzes showed a high concentration of total organic carbon in the first 10 centimeters of the soil (3.7 g 100 g -1). It is the same for the concentration of total nitrogen around 0.275 g kg-1. In the 50-100 cm layer, low carbon and nitrogen contents estimated respectively at 1.125 g 100 g-1 and at 0.025 g kg-1 have been spotted.

The participants were subjected to two physical exercise sessions (aerobics alone and then, aerobics and muscle strengthening) during one week. Data were collected using a questionnaire. The form of the session was considered acceptable if its assessment based on 6 items scored at least 13.6 out of a total of 17 points; accessible if its assessment based on 5 items scored 14.4 out of a total of 18 points. It was considered effective if it met 4 of the physiological criteria.

The results showed that double disinfection resulted in the lowest contamination rates of 5.29% and 9% for calcium hypochlorite and sodium hypochlorite, respectively. Germination rates, mean germination times, and viable seedling rates were not affected by the disinfection technique nor type of disinfectant used. However, plants from seeds that underwent double disinfection had the highest growth rates. The presence of antioxidants and the interaction between antioxidants and their concentrations did not have a significant influence on germination rates, normal seedling rates, or mean germination time.

This study focused on refining the absorbance efficiency of Pugu kaolin clay from Tanzania to enhance its utilization in removing textile dyes from contaminated water. The process involved acid-activation after calcination at 750oC. Characterization using X-ray Fluorescence (XRF), X-ray diffraction (XRD), Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR) and Porosimeter techniques revealed the presence of kaolinite [Al2Si2O5(OH)4], silica (SiO2) and microcline [KAlSi3O8] as the main phases. Acid treatment resulted in an increase in silica content from 44.18% to 58.81% due to the appearance of tridymite, while alumina decreased from 26.70% to 12.74% due to the removal of kaolinite. Surface area significantly expanded from 15.36 to 149.61 m2/g as acid-soluble impurities were eliminated. Chemical composition was also altered, with a decrease in Fe2O3 and increase in other major oxides. The impact of acid activation on the adsorption capacity of the clay was investigated by studying various parameters such as contact time, temperature, adsorbent dose, initial pH and adsorbate concentration. Basic Blue 9 (BB9) and Direct Red 28 (DR28) dyes were used as model adsorbates. The results obtained at optimal conditions of 3 hours contact time, 27oC temperature, 0.9 g adsorbent dose, initial pH of 11 and initial adsorbate concentration of 90 mg/L, showed that acid modification of the clay increased its capacity to adsorb BB9 from 96.82% to 99.91%, and DR28 from 86.33% to 95.04%. These findings underscore the positive impact of modifying the raw clay, enhancing its suitability for dye removal applications.","PeriodicalId":13808,"journal":{"name":"International Journal of Biological and Chemical Sciences","volume":"117 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139615231","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}

Similarly, on each pond and during each campaign, measurements of environmental variables were carried out either in situ or in the laboratory. A total of 64 taxa of aquatic macroinvertebrates belonging to 33 families, 11 orders and 04 classes were recorded. Insects were the most diversified, accounting for 79.68% of the taxonomic richness. Five major FFGs were identified in this study: predators, scrapers, shredders, gatherers-collectors and filter-collectors, with predators dominating, followed by gatherers-collectors. The P/R ratio indicated that all three ponds were heterotrophic. The predator top-down ratio revealed an overabundance of predators. Only the riparian zones of pond P1 were functional. The Focused Principal Component Analysis found a correlation between low pH values and the abundance of predators and scrapers. There was also a correlation between high nitrate levels and gatherers-collectors abundance.

An inventory of tree species in eighteen cocoa and rubber plantations was conducted respectively in 45 plots of 400 m² each. Also, 15 plots of the same area were delimited in forests considered as reference systems. Cocoa plantations are 8 times richer than rubber plantations. Moreover, tree density varied from 36 to 56.8 stems.ha-1 in cocoa plantations including 6 species with special-status for conservation and from 0 to 5 stems.ha-1 in rubber plantations. This study confirmed that rubber farming is a driver of tree diversity loss thereby revealing the need to work out credible rubber agroforestry options. As for cocoa farming, the high diversity of companion trees is indicative of the high potential of transitioning to cocoa agroforestry.
