What is the process of mechanically introducing oxygen back into the soil?

The process of mechanically introducing oxygen back into the soil is known as aeration. Aeration is essential for maintaining healthy soil, as it allows for the exchange of gases between the soil and the atmosphere. By creating small holes in the soil, aeration improves the penetration of air, water, and nutrients to the roots of plants. This process can significantly enhance microbial activity, promote root growth, and improve overall soil structure.

Other terms like agitation, adsorption, and absorption refer to different processes. Agitation typically involves stirring or mixing substances and is not directly related to soil health. Adsorption pertains to the process in which atoms, ions, or molecules from a gas, liquid, or dissolved solid adhere to a surface, while absorption is the process of one substance being taken up into another substance in a manner that changes its state or nature. Neither of these processes directly involves the mechanical introduction of oxygen into the soil. Thus, aeration is the correct term for this important practice in turf and ornamental weed management.
