Answer Details
The amount of air and water in the soil is mostly affected by the structure of the soil. Soil structure refers to the arrangement of soil particles into aggregates or clumps. The spaces between these aggregates determine the amount of air and water in the soil. If the soil has a good structure with well-formed aggregates, there will be more spaces for air and water to move through the soil. On the other hand, if the soil has poor structure, with few or no aggregates, the soil will have poor aeration and drainage. The other options, such as location, rainfall, chemical composition, and living organisms, can also have an impact on soil air and water content, but they are not the primary factors.
