Question
The soils of grassland ecosystems, characterized by a
thick, dark surface horizon comes under which soil order?Solution
Mollisols are the soils of grassland ecosystems. They are characterized by a thick, dark surface horizon. This fertile surface horizon, known as a mollic epipedon, results from the long-term addition of organic materials derived from plant roots Mollisols are among some of the most important and productive agricultural soils in the world and are extensively used for this purpose
