Which of the following describes soil with a granular structure?

Soil with a granular structure is characterized by its ability to crumble and break apart easily, creating a loose texture that enhances aeration and drainage. In granular soils, the individual particles are often rounded or nearly spherical, allowing them to fit together in a way that creates spaces or pores between them. This structural arrangement is beneficial for root growth and water infiltration, as it facilitates movement within the soil.

The ease of crumbling is indicative of a well-developed granular structure that has sufficient organic matter and stable aggregates. Such soils typically exhibit a high level of biological activity, which contributes to their favorable characteristics.

Other descriptions such as being very smooth and compact, soft and loose, or rough and chunky do not accurately define the distinctive properties of granular soil structure. A smooth and compact soil often indicates a lack of granulation and possibly higher clay content, whereas soft and loose may refer to less cohesive soils, lacking the structured form that defines granularity. Rough and chunky may suggest larger soil aggregates but does not capture the specific crumbliness associated with granular soils.
