Thesis Abstract

Abstract
Soil microbial diversity and activity play crucial roles in maintaining soil health and ecosystem functioning. Understanding how different land use systems impact soil microbial communities is essential for sustainable land management practices. This thesis aims to assess soil microbial diversity and activity in various land use systems, including agricultural, forested, and urban areas. The first chapter provides an introduction to the importance of soil microbes, the background of the study, problem statement, objectives, limitations, scope, significance, and structure of the thesis. Definitions of key terms related to soil microbial diversity and activity are also provided. Chapter two presents a comprehensive literature review covering ten key aspects related to soil microbial diversity and activity in different land use systems. This includes discussions on the effects of land use change on soil microbial communities, the role of soil microbes in nutrient cycling, and the impact of agricultural practices on soil microbial diversity. Chapter three outlines the research methodology employed in this study. It includes detailed descriptions of the sampling design, soil microbial analysis techniques, data collection procedures, and statistical analyses used to assess soil microbial diversity and activity across different land use systems. Additionally, factors such as soil pH, moisture content, and temperature are considered in the analysis. Chapter four presents the findings of the study, with an elaborate discussion on how soil microbial diversity and activity vary across agricultural, forested, and urban land use systems. The results highlight significant differences in microbial community composition, abundance, and functional diversity among the different land use types. In the final chapter, chapter five, the conclusions drawn from the study are summarized, emphasizing the implications of the findings for land management practices. Recommendations for sustainable soil management strategies that promote soil microbial diversity and enhance soil health in various land use systems are also discussed. Overall, this thesis contributes to the understanding of soil microbial diversity and activity in different land use systems and provides valuable insights for sustainable land management practices. The findings underscore the importance of preserving soil microbial communities to ensure the long-term productivity and sustainability of terrestrial ecosystems.
