Quality Control and Verification of Bio-Solid from Human Faecal Matter in Plant Growth Studies

Abstract

The objective of this study is to evaluate the quality, safety, and agricultural efficacy of biosolids derived from human faecal matter. By focusing on the chemical, biological, and environmental properties of biosolids, the study aims to provide a comprehensive understanding of their potential as a sustainable alternative to conventional chemical fertilizers. The investigation emphasizes key aspects such as pathogen reduction, heavy metal stabilization, nutrient content, and the broader impact on plant growth. These aspects align directly with the findings from the data analysis, which reflect both the effectiveness and safety of biosolid use in agricultural applications.

In terms of methodology, the research employs statistical techniques including ANOVA and regression analysis. ANOVA is used to assess the significance of the data, while regression analysis examines the relationships between biosolid treatment and plant growth, as well as public perceptions of biosolid use. This methodological framework ensures the reliability of the study’s findings.

The key findings highlight a strong public acceptance of biosolids, with 63.6% of respondents strongly agreeing that biosolids are a viable and beneficial agricultural input. The results of the regression analysis further underscore the positive correlation between awareness and acceptance of biosolids, confirming that increased knowledge leads to higher acceptance rates. The statistical significance, indicated by R² = 0.515 and a p-value of 0.000, reinforces the validity of the results. These findings are critical in supporting the hypothesis that biosolids are a sustainable alternative to chemical fertilizers. The study concludes that with the right treatment processes, biosolids can offer a cost-effective and environmentally responsible solution for enhancing soil fertility and promoting sustainable agricultural practices.
