The ability of soil to absorb and allow water and air to pass through is not related to which of the following?

The ability of soil to absorb and allow water and air to pass through is primarily influenced by factors such as texture, granular structure, and the overall physical characteristics of the soil. Texture refers to the size of soil particles and their distribution, which significantly affects porosity and permeability. Granular structure also plays a role, as it determines how soil particles aggregate and form spaces for air and water movement.

Cation exchange capacity, while an essential property of soil that relates to its ability to hold onto cations (positively charged ions), is not directly related to the physical processes of absorption and permeability regarding water and air. Cation exchange capacity primarily impacts nutrient availability and soil fertility rather than physical properties affecting water and air flow. Therefore, it is less relevant to the question of how well water and air can move through the soil.
