Answer
A farmer can utilize subsoiling or ploughing methods to break up the soil structure. This action improves airflow by creating more pore spaces, thus preventing the soil from becoming waterlogged and enhancing aeration for aerobic microorganisms in the rhizosphere.

Answer
Introducing earthworms into the soil can also increase airflow. Earthworms burrow through the soil, creating channels that enhance porosity and allow for better air circulation, thereby supporting increased respiration in the rhizosphere.
