Treffer: Optimizing Fertilizer Production: Co-Composting Faecal Sludge With Various Bulking Agents.

This research investigates the integration of locally available bulking agents--coconut shells, waste tea powder, banana peels, and sugarcane leaves--for co-composting fecal sludge (FS) alongside organic waste. The study involves physical, chemical, and heavy metal analysis of the bulking agents, followed by 91 days of aerobic composting with weekly sample collection and evaluation. The goal was to identify the optimum combination of these agents for producing nutrient-rich compost, particularly for nitrogen (N), phosphorus (P), and potassium (K). The compost prepared using a specific combination of these bulking agents met the key nutrient criteria, providing a viable solution for sustainable waste management. Coconut shells enriched the compost with potassium, calcium, magnesium, and phosphorus, enhancing soil structure and moisture retention. Waste tea powder, rich in nitrogen and potassium, promoted microbial activity and soil fertility. Banana peels contributed high levels of potassium and phosphorus, improving aeration and nutrient cycling, while sugarcane leaves enhanced soil health by contributing organic carbon, nitrogen, and potassium. The study utilized tools like Python and Microsoft Excel for data analysis and visualization, enabling the establishment of reliable maturity indices for assessing compost stability and quality. These findings highlight the potential of using locally available organic waste materials to improve soil fertility and support sustainable agricultural practices. [ABSTRACT FROM AUTHOR]

المقال يركز على تحسين إنتاج الأسمدة من خلال التسميد المشترك للحمأة البرازية مع مجموعة متنوعة من المواد المساعدة المتاحة محليًا، بما في ذلك قشور جوز الهند، وقشور الموز، وأوراق قصب السكر، ومسحوق الشاي المستعمل. تهدف الدراسة إلى تحديد أفضل تركيبات لهذه المواد لإنتاج سماد غني بالعناصر الغذائية، مع تعزيز مستويات النيتروجين والفوسفور والبوتاسيوم. تسلط الدراسة الضوء على الفوائد الكبيرة لاستخدام قشور جوز الهند، التي تحسن جودة السماد من خلال تقليل فقدان النيتروجين وتعزيز احتفاظ العناصر الغذائية، مما يوفر حلاً مستدامًا لإدارة النفايات والممارسات الزراعية. تؤكد النتائج على إمكانية استخدام المواد العضوية المحلية لتحسين خصوبة التربة وتعزيز الأساليب الزراعية المستدامة.
