Soil microbial diversity refers to the variety and abundance of microorganisms, such as bacteria, fungi, and archaea, present in soil ecosystems. These microbes play crucial roles in nutrient cycling, decomposition, and plant health. Research in this area aims to understand the factors that influence microbial diversity in soil, such as soil type, land use practices, and environmental conditions. By studying soil microbial diversity, researchers can gain insights into the functioning of soil ecosystems and develop strategies for sustainable soil management practices.
