Thesis Abstract

Abstract
The health and diversity of soil microbial communities play a crucial role in maintaining soil fertility, supporting plant growth, and sustaining agricultural productivity in agroecosystems. The present study aimed to assess soil health and microbial diversity in agroecosystems to gain insights into the intricate relationships between soil properties, microbial communities, and agricultural sustainability. Chapter One provides the introduction to the study, background information, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of terms. The introduction highlights the importance of soil health and microbial diversity in agroecosystems and the need for a comprehensive assessment to enhance agricultural practices. Chapter Two presents a comprehensive literature review on soil health, microbial diversity, and their roles in agroecosystems. The review covers ten key aspects related to soil health assessment, microbial community structure, functions, interactions, and their influences on plant growth and ecosystem services. Chapter Three details the research methodology employed in the study, including sample collection, soil analysis techniques, microbial community profiling methods, data analysis procedures, and statistical tools used to evaluate soil health parameters and microbial diversity in agroecosystems. The chapter outlines eight key methodological steps undertaken to achieve the study objectives. Chapter Four comprises an in-depth discussion of the findings obtained from the soil health assessment and microbial diversity analysis in agroecosystems. The chapter delves into the relationships between soil properties, microbial community composition, diversity indices, and the implications for agricultural sustainability. It also explores the role of management practices in shaping soil health and microbial communities. Chapter Five presents the conclusion and summary of the project thesis, highlighting the key findings, implications, and recommendations for future research and agricultural practices. The study underscores the importance of maintaining soil health and microbial diversity in agroecosystems to enhance soil fertility, crop productivity, and environmental sustainability. In conclusion, the assessment of soil health and microbial diversity in agroecosystems provides valuable insights into the complex interactions between soil properties, microbial communities, and agricultural sustainability. The findings of this study contribute to the growing body of knowledge on soil health management and microbial diversity conservation in agroecosystems, with implications for sustainable agriculture and ecosystem resilience.
