Abstract:
This research project aims to investigate the role of plant root exudates in shaping soil microbial communities. Plant roots release a variety of organic compounds known as root exudates into the soil, which can influence the composition and activity of soil microbial communities. Understanding the interactions between plant root exudates and soil microbes is crucial for unraveling the complex dynamics of soil ecosystems and their impact on plant health and nutrient cycling. This study will involve the collection of root exudate samples, analysis of microbial community composition, and assessment of microbial activity in controlled experiments. The findings will contribute to our understanding of the intricate relationships between plants and soil microbes, providing insights into the potential applications of root exudates in sustainable agriculture and soil management practices.
