Soil contamination

Soil contamination is the presence of man-made chemicals or other alteration to the natural soil environment.

This type of contamination typically arises from rupture of underground storage tanks, application of pesticides and herbicides, percolation of contaminated surface water to subsurface strata, leaching of wastes from landfills or direct discharge of industrial wastes to the soil.

United Against Soil Erosion: German Farmers in Georgia

Deutsche Welle (Nov. 4, 2012) Less rainfall due to climate change and strong mountain winds are causing serious soil erosion in Georgia.

Even though Georgia's soil is richer in minerals than Germany's, soil erosion has reduced harvests there by up to 40 percent. Now German farmers are providing tips to their Georgian counterparts to help them slow down soil erosion.

Farming Revolution in South Africa

Farming Revolution in South Africa

Deutsche Welle (Feb. 20, 2012) A new project in South Africa is taking organic waste that would otherwise be left to simply decay in garbage dumps and processing it in a special facility belonging to the South African company Reliance. There, it is converted it into microbiological compost. The project prevents some 100,000 tons of methane gas being emitted into the atmosphere each year. In addition, the compost helps to improve the quality of the soil, makes plants more robust and helps farmers cut down on the use of pesticides. It's also helping South Africa tackle one of its biggest problems: the massive use of chemical fertilizers in the country has made the ground infertile, caused soil erosion and led to contaminated water.
