Which soil characteristic is NOT related to the soil's ability to absorb water?

The ability of soil to absorb water is closely linked to its physical and chemical properties. Factors such as texture, which refers to the size of the soil particles (sand, silt, clay), significantly influence water retention and permeability. More textured soils tend to have better drainage or greater water retention capabilities depending on their composition.

Granular structure also plays a role in water absorption. Soils with good granular structure tend to have better aeration and drainage, enhancing their capacity to absorb and retain water.

However, color, while indicative of certain soil characteristics, such as organic matter content or mineral composition, does not directly affect the physical processes involved in water absorption. A soil's color does not determine how much water it can hold or how quickly water can move through it, which is why it is not related to the soil's ability to absorb water in a significant way.
