Which of the following describes poorly drained soils?

The correct choice highlights the various classifications of drainage conditions found in soils. Poorly drained soils are characterized by their inability to effectively manage water, which leads to prolonged saturation and limited aeration. The categories mentioned—somewhat poorly drained, poorly drained, and very poorly drained—reflect a spectrum of drainage conditions that are key for understanding how water behaves in these soils.

Somewhat poorly drained soils may hold water longer than well-drained soils but will still have some capacity for water movement. Poorly drained soils retain water for extended periods, creating conditions that can lead to reduced oxygen levels necessary for root growth. Very poorly drained soils are continuously saturated, severely limiting their usability for agricultural purposes unless managed properly.

Understanding these distinctions is crucial for soil management and agriculture, as the drainage classification influences plant health, agricultural productivity, and land use practices. This clarity in terminology helps land users determine appropriate practices for soil management, making option B the most informative and relevant choice.
