Question

Desert soils lack humus because of which of the following reasons?

• A. Developed irrigation
• B. Lack of vegetation
• C. Lack of rainfall
• D. None of these

Answer 1

Answer: (B)

Lack of vegetation

Desert soils range from red to brown in color. They are generally saline in nature. Desert soils lack humus due to lack of vegetation in desert areas. Humus is a dark, organic material that forms in soil when plant and animal matter decays. If there will be a lack of vegetation, then no humus will form in desert soils.
