If a soil has a capability subclass of "f," what does this indicate about its fertility?

A capability subclass of "f" specifically corresponds to soils that are considered to have low fertility, primarily due to limitations such as poor nutrient availability, inadequate drainage, or other natural characteristics that hinder productive use in agriculture. This classification helps land users understand the potential productivity of the soil and make informed decisions regarding land management and crop selection.

Soils with subclasses indicating higher fertility would differ significantly in their ability to support a wide variety of crops, demonstrating traits that promote nutrient retention and water availability. In contrast, those with a subclass of "f" require specific management practices to enhance their productivity, which could include adding fertilizers or improving soil structure, but fundamentally, they are recognized for their inherent limitations regarding fertility.
