Which subclass refers to soils of low fertility that can potentially be corrected with careful management?

The correct answer is Subclass F, which refers to soils that are characterized by low fertility. This designation is significant because it indicates that while these soils are not currently fertile, there is potential for improvement through careful management practices. This could involve strategies such as proper fertilization, crop rotation, and soil amendments to enhance fertility levels.

Understanding the characteristics of Subclass F is crucial for effective soil management in agricultural practices, especially in rural areas where maximizing productivity can be challenging due to soil limitations. Hence, farmers and land managers can target these soils for specific interventions aimed at restoring or enhancing their fertility.

In contrast, the other subclasses do not specifically focus on low fertility soils or their potential for improvement, which is why they do not align with the context of this question.
