Which soil characteristics are the most desirable for agriculture?

Question

Quizplus · Accepted Answer

High cation exchange capacity (CEC) is desirable because it means the soil can hold onto nutrients and make them available to plants. A small E horizon is also desirable because it means the soil has a good structure, with layers that allow for water and air movement, and is likely to have sufficient organic matter to support plant growth. Therefore, option C (high CEC and a small E horizon) is the best choice for agriculture.
