A Picture Story About Soil Erosion
(Story Coming Soon)

Here are some photos that tell a tale about soil erosion from Dr. Ray Weil, a soil scientist from the University of Maryland, College Park, MD, USA. The soil story about these images is coming soon. In the meantime take a look at the pictures.

Muddy runoff from tilled fields in Ethiopia

Sediment-laden river running through a city (Addis Ababa, Ethiopia) many miles downstream from the eroding soils.

Dr. Ray Weil in Ethiopia. The soil clods that you will see below were taken from this site. In the background we see natural vegetation (actually 30 to 40 year old Eucalyptus trees and grass under story) and in the foreground we see the cultivated field (potato, wheat, bean rotation). This site is in the central highlands of Ethiopia on a government research farm.

Soil clods before they are put into the water.

The same soil clods after they have been placed into the water. What do you see? Do you see any differences between the soil clods in the different beakers?

How about now?
