The nitrates in the soil are converted to atmospheric nitrogen by denitrifying bacteria. The nitrogen cycle is a continuous process where nitrogen moves between the atmosphere, soil, and living organisms. Nitrates are produced in the soil through the process of nitrification, where nitrogen-fixing bacteria convert atmospheric nitrogen into nitrates. However, these nitrates can then be converted back into atmospheric nitrogen by another type of bacteria called denitrifying bacteria. Denitrifying bacteria are responsible for breaking down nitrates into nitrogen gas, which is then released back into the atmosphere. This process helps to maintain a balance of nitrogen in the ecosystem and ensures that plants and other living organisms have access to the nitrates they need for growth.
