Soil bacteria play a vital part in the biochemical cycles, impacting nutrient availability, ecosystem functioning, and global biogeochemical processes. This abstract explores the significance of soil bacteria in biochemical cycles, focusing on their roles in carbon, nitrogen, sulfur cycle, phosphorus, iron cycle and manganese cycles. Soil bacteria, responsible for fixing nitrogen, nitrify and denitrify also mineralize organic phosphorous into soluble form. These correlations is essential for implementing sustainable soil management techniques and reducing ecological deterioration. These interactions can be disturbed by anthropogenic activity, which calls for more investigation to comprehend their processes along with responses to environmental changes. Overall, soil bacteria are essential regulators of biochemical cycles, and maintaining environmental balance. Understanding the intricate interactions between soil bacteria and biochemical cycles is crucial for effective soil management, ecosystem conservation, and sustainable development practices. The aim of the paper is to identify and characterize the bacterial communities involved in these cycles and to determine their contributions to soil health and plant growth. We conducted a comprehensive analysis of soil samples from various ecosystems, using both culture-dependent and culture-independent methods. High-throughput sequencing and metagenomic approaches were employed to identify bacterial taxa and their functional genes related to biochemical cycles. We found that certain bacterial taxa, such as Rhizobium, Pseudomonas, and Bacillus, play pivotal roles in nitrogen and phosphorus cycling. Our data indicated that microbial diversity and activity are closely linked to soil organic matter. These findings can inform sustainable land management practices and enhance our ability to predict and mitigate the impacts of environmental changes on soil ecosystems.
