Soil microbial research focuses on studying the various microorganisms present in soil, such as bacteria, fungi, and protozoa, and their interactions with each other and with plants. These soil microbes play critical roles in nutrient cycling, soil health, and plant growth, making them essential for agriculture and ecosystem functioning. Researchers in this field investigate the diversity, abundance, and functions of soil microbes, as well as how they respond to environmental changes, management practices, and contamination. Soil microbial research is important for understanding and improving soil quality, sustainability, and productivity in various ecosystems.
