What is a key feature of a Coarse B horizon in texture consistency?

The key feature of a Coarse B horizon is that it feels sandy and is not dirty. This horizon typically consists of larger particles, allowing for better drainage and air movement compared to finer-textured horizons. A coarse texture, often characterized by sand or silt-sized particles, will feel gritty to the touch and lacks the stickiness often associated with finer textures like clay. Additionally, the term "not dirty" suggests that this horizon is relatively clean, with fewer fine particles or organic matter mixed in, aligning with the characteristics of a coarse texture.

In contrast, other options describe textures that are more associated with fine or medium-textured soils. The stickiness and ribbon formation indicate a higher clay content, while descriptions of components like rocks, gravel, or softness relate more to other soil types rather than the specific qualities of a Coarse B horizon. Understanding the tactile characteristics of soil horizons is essential in soil judging to accurately identify and classify different soil types based on texture and composition.
