Thesis Overview

The project titled "Assessment of soil microbial diversity and its impact on soil health in agricultural lands" aims to investigate the relationship between soil microbial diversity and soil health in agricultural lands. Soil microbial communities play a crucial role in nutrient cycling, soil structure formation, and overall ecosystem functioning. Understanding the diversity of soil microbes and their impact on soil health is essential for sustainable agricultural practices and soil management. The research will involve conducting a comprehensive analysis of soil samples from different agricultural lands to assess the microbial diversity present. Various molecular techniques, such as next-generation sequencing, will be employed to identify and quantify the microbial taxa present in the soil. The abundance and diversity of microbial communities will be examined in relation to soil health indicators, such as soil organic matter content, nutrient availability, and physical properties. The project will also investigate the potential effects of agricultural practices, such as tillage, crop rotation, and fertilizer application, on soil microbial diversity and soil health. By comparing soil samples from different management practices, the research aims to identify the most sustainable approaches that promote beneficial soil microbial communities and enhance soil health. Furthermore, the study will assess the functional diversity of soil microbes by examining their roles in key soil processes, such as nitrogen fixation, carbon sequestration, and disease suppression. Understanding the functional capabilities of soil microbes will provide valuable insights into their contributions to soil health and ecosystem services. Overall, this research project seeks to advance our knowledge of soil microbial diversity and its implications for soil health in agricultural lands. By elucidating the complex interactions between soil microbes and soil health indicators, the findings of this study will contribute to the development of science-based strategies for improving soil quality, enhancing crop productivity, and promoting sustainable agriculture practices.
